What must you change if rain or oil spillage reduces the frictional force?

The total displacement of the car is the sum of the displacement during acceleration and deceleration, which is 155.44 - 254.24 = -98.8 m. So, the car moves backwards 98.8 m during the entire motion.

The total displacement of the car can be calculated as follows:

The car accelerates from rest to 25.4 m/s with an acceleration of 4.51 m/s2. The time taken to reach this speed can be calculated as t = v / a = 25.4 / 4.51 = 5.6 s

During the time t, the car travels a distance x = 0.5at^2 + v_0t, where v_0 is the initial velocity, which is zero.

The distance covered during acceleration is x = 0.5 * 4.51 * 5.6^2 = 155.44 m

The car then slows down with an acceleration of -2.34 m/s2. The time taken to slow down from 25.4 m/s to 0 m/s can be calculated as t = v / a = 25.4 / 2.34 = 10.8 s

During this time, the car travels a distance x = 0.5at^2 + v_0t = 0.5 * -2.34 * 10.8^2 + 25.4 * 10.8 = -254.24 m

a=f/m

f=a1/5. ... (1) f=a2/0.5.... (2)

a1/a2=10/1

cat accelerate fast

We want to see which one of the two animals accelerates the fastest. We will see that the mouse is the one that accelerates the fastest.

The first thing you need to remember is Newton's second law.

Force equals mass times acceleration, or:

F = m*a

We know that the mass of the cat is:

M = 5kg

the mass of the mouse is:

m = 0.5kg

If we apply the same force F to both animals, we will get:

for the cat:

F = 5kg*a

For the mouse:

F = 0.5kg*a'

Solving these equations for a and a' we get:

a = F/5kg

a' = F/0.5kg

So a' has a smaller denominator, thus, the value of a' is larger, which implies that the mouse is the one that accelerates the fastest.

First off, let's call the -15 degree water solution1, and the 32 degree water solution2. The formula for this is

\(t_f=\frac{(m_1*spheat_1*temp_1)+(m_*spheat_2*temp_2)}{(m_1*spheat_1)+(m_2*spheat_2)}\)

where spheat is specific heat of water that I found to be 4182 J/(kgC). This means that we need our masses in kg and they are currently in g.

100 g = .100 kg and

220 g = .220 kg. Now we're ready to plug everything in:

\(t_f=\frac{(.100*4182*-15)+(.220*4182*32)}{(.100*4182)+(.220*4182)}\) and

\(t_f=\frac{-6273+29441.28}{418.2+920.04}\) and

\(t_f=\frac{23168.28}{1338.24}\) so

Based on the calculations, the radius of a tantalum (Ta) atom is equal to 0.143 nm.

Given the following data:

Density of tantalum (Ta) = 16.6 g/cm³.

Atomic weight of tantalum (Ta) = 180.9 g/mol.

Density can be defined as a ratio of mass to the volume of a physical object such as a tennis ball. Mathematically, the density of a physical object can be calculated by using this formula:

Density = Mass/Volume

For the mass of this unit cell, we have:

Mass = 2 atoms/unit-cell  × 180.9 g/mol × 1  mol /6.022 x 10²³ atoms/mol

Mass = 6.01  x 10⁻²² g/unit-cell

Next, we would determine the volume and edge length of the cube:

Volume, V = 6.01 x 10⁻²²/16.6

Volume, V = 3.62 x 10⁻²³ cm³

For the edge length, we have:

V = a³

a = ∛V

a = ∛3.62 x 10⁻²³ cm

Edge length, a = 3.31 x 10⁻⁸ cm

Mathematically, the edge length of a body-centered cubic unit cell is given by this formula:

a = 4r/√3

r = a × √3/4

r =  3.31 x 10⁻⁸ × √3/4

Radius, r = 1.43 × 10⁻⁸ cm

Lastly, we would convert the value in cm to nm:

Radius, r = 1.43 × 10⁻⁸ × 1/100 × 1 × 10⁹

Explanation:

A child sleds down a steep, snow-covered hill with an acceleration of 2.82m/s squared. if her initial speed is 0.0 m/s and her final speed is 15.5 m/s, It takes the child 5.50 seconds to travel from the top of the hill to the bottom.

We can use the following kinematic equation to solve this problem:

v^2 = u^2 + 2as

Where:

v is the final speed

u is the initial speed

a is the acceleration

s is the distance traveled

We are given u = 0.0 m/s, a = 2.82 m/s^2, and v = 15.5 m/s. We need to find s.

Rearranging the equation gives:

s = (v^2 - u^2) / (2a)

Substituting the values gives:

s = (15.5^2 - 0.0^2) / (2 x 2.82) = 74.47 m

Now, we can use another kinematic equation to find the time taken:

v = u + at

Where t is the time taken.

Substituting the values gives:

15.5 = 0.0 + 2.82t

Solving for t gives:

t = 15.5 / 2.82 = 5.50 seconds

The mass of the block is 20Kg. The force applied is 50 N and the angle at which the force is applied is 25°. The coefficient of friction is 0.20.

When the block will be pulled along horizontal by applying Force fat an angle A, then there will be two components of force one along vertical fsinA and one along horizontal fcosA.

The friction will be in opposite direction,

So, we can say, the net Force F on the block is,

Explanation:

The charge q1 must be 4.31 pC in magnitude and positive. Therefore, q1 = 4.31 pC.

To obtain a net electric field of zero, a third charge has to be positioned at x=24 cm. The two point charges are located on the x-axis, as shown in the diagram below. The + 2.60 pC charge is at the origin, and the − 4.70 pC charge is at x=−11.0 cm. The third charge must be positioned at x=24 cm. The total electric field will be zero at x=12 cm if the charge is q = 4.31 pC.

The electric field E caused by a point charge q is given by: E=kq/r²where k is Coulomb's constant, k=9.0x10⁹ N m²/C²;r is the distance between the point charge and the test charge, and is the displacement from the point charge to the test charge.

Let's suppose that the third charge is q1, and let's calculate its value using the electric field expression: E = kq/r².

The net electric field at point P, which is 12.0 cm from the origin, can be calculated using the following formula:

E=PQ/R² - Q/ (R+D)² where P is the charge at the origin, Q is the charge at -11.0 cm, R is the distance from point P to the origin, D is the distance between Q and P.

E = 0, which implies that: PQ/R² = Q/ (R+D)²Let R = 12 cm and D = 24 + 11 = 35 cm Q/P = (R/D)1/2Q/P = (12/35)1/2Q = 4.71 pC (charge at x = -11 cm)P = 2.60 pC Charge Q is negative, and charge P is positive.

If the net electric field is zero, the charge q1 must be positive, and its magnitude must be 4.31 pC. This is because charge q1 will produce an electric field that is equal in magnitude and opposite in direction to the combined electric field produced by charges P and Q.

The charge q1 must be 4.31 pC in magnitude and positive. Therefore, q1 = 4.31 pC.

The third charge q3 required at x = +24 cm is +5.01 pC.

The electric field produced by the charges should cancel out at the third point, so we can calculate the value of the third charge by making use of the principle of superposition. Therefore, the third charge that should be placed at x = +24 cm is +5.01 pC.

The principle of superposition in physics is an important concept. The principle of superposition holds that when two or more waves meet, their combined effect is equal to the algebraic sum of their individual effects. The principle of superposition is valid in most wave phenomena, such as sound waves, water waves, and electromagnetic waves.

Superposition of electric field

In this problem, we are required to find the charge q3 required at x = +24 cm so that the net electric field at x = +12.0 cm is zero.

Let's first calculate the electric field due to q1 and q2. We know that the electric field at any point on the x-axis due to a point charge can be calculated using Coulomb's law as:

E = (1/4πε0) × [(q1 / r1^2) + (q2 / r2^2)]

Where:

E is the electric field,

q1 and q2 are the charges,

r1 and r2 are the distances from the charges,

ε0 is the electric constant.

Consider the positive x-axis for q1 and the negative x-axis for q2. Then,

r1 = 12.0 cm = 0.12 m

r2 = 24 cm + 12 cm = 36 cm = 0.36 m (since q2 is to the left of the origin)

r1 = 0.12 m, and r2 = 0.36 m.

q1 = +2.60 pC = 2.60 × 10⁻¹² C

q2 = -4.70 pC = -4.70 × 10⁻¹² C

ε0 = 8.85 × 10⁻¹² F/m²

Electric field due to q1:

E1 = (1/4πε0) × [(q1 / r1^2)] = (1/4π × 8.85 × 10⁻¹²) × [(2.60 × 10⁻¹²) / (0.12)²] = 4.68 × 10⁴ N/C (to the right of the origin)

Electric field due to q2:

E2 = (1/4πε0) × [(q2 / r2^2)] = (1/4π × 8.85 × 10⁻¹²) × [(-4.70 × 10⁻¹²) / (0.36)²] = 0.573 × 10⁴ N/C (to the left of the origin)

Therefore, the net electric field at x = 12.0 cm is:

E = E1 + E2 = 4.68 × 10⁴ - 0.573 × 10⁴ = 4.11 × 10⁴ N/C (to the right of the origin)

Since the electric field at x = +12.0 cm is not zero, we need to add a third charge q3 such that the net electric field is zero.

Now consider the positive x-axis to be the reference axis, the direction of E1 (from q1) and E2 (from q2) is to the right and left, respectively. Let's assume that the direction of the electric field from q3 is to the left. The net electric field at x = +12.0 cm can be zero if:

E1 + E2 + E3 = 0

E3 = - (E1 + E2)

E3 = - (4.68 × 10⁴ + (-0.573 × 10⁴))

E3 = 5.01 × 10⁻¹² C

Therefore, the third charge q3 required at x = +24 cm is +5.01 pC.

Apply the SUVAT equation \({v_{1}}^{2} - {v_{0}}^{2} = 2\, a\, x\) to the vertical component of the soccer ball's motion to find the vertical velocity right before the ball lands. In this equation:

Rearrange this equation to find an expression for the vertical velocity \(v_{1}\) in terms of \(y\) and \(g\):

\(\begin{aligned}v_{1} &= \sqrt{{v_{0}}^{2} + 2\, a\, x} \\ &= \sqrt{2\, g\, y}\end{aligned}\).

Since air friction is negligible, the horizontal velocity of the ball would stay unchanged. Thus, the horizontal velocity of the ball would still be \(v\) right before the ball lands.

Notice that these two components of velocity are perpendicular to one another. Thus, find the combined velocity of the ball right before landing could be found using Pythagorean's Theorem:

\(\sqrt{v^{2} + {v_{1}}^{2}} = \sqrt{v^{2} + 2\, g\, y}\).

When a force is applied to a spring, its length changes according to Hooke's Law, which states that the force (F) acting on a spring is proportional to its elongation (x). The formula for Hooke's Law is F = kx, where k is the spring constant.

In this problem, we are given the length of the spring (14 cm) when a force of 4N is applied. We are also given that when the force is increased to 6N, the spring extends by an additional 4 cm. We can use this information to find the unstretched length of the spring. First, let's find the spring constant (k) using the initial force and length. Using Hooke's Law: 4N = k(14 cm). Next, we can find the elongation caused by the 6N force: 6N = k(x + 14 cm), where x is the additional extension due to the increased force. Now, we know that the 6N force causes the spring to extend by 4 cm, so we can write: 6N = k(4 cm + 14 cm), 6N = k(18 cm). We can solve for the spring constant (k) using the initial equation: k = 4N / 14 cm ≈ 0.286 N/cm. Now, plug this value into the equation with the 6N force: 6N = (0.286 N/cm)(18 cm). Solving for the unstretched length, we can subtract the total elongation (18 cm) from the length under the 6N force: Unstretched length = 18 cm - 4 cm = 14 cm. So, the unstretched length of the spring is 14 cm.

Answer:

Seafloor spreading occurs because earthquakes break apart the ocean floor.

Seafloor spreading is a geologic process where there is a gradual addition of new oceanic crust in the ocean floor through a volcanic activity while moving the older rocks away from the mid-oceanic ridge. The mid-ocean ridge is where the seafloor spreading occurs, in which tectonic plates—large slabs of Earth’s Lithosphere—split apart from each other.

Seafloor spreading was proposed by an American geophysicist, Harry H. Hess in 1960. By the use of the sonar, Hess was able to map the ocean floor and discovered the mid-Atlantic ridge (mid-ocean ridge). He also found out that the temperature near to the mid-Atlantic ridge was warmer than the surface away from it. He believed that the high temperature was due to the magma that leaked out from the ridge. The Continental Drift Theory of Alfred Wegener in 1912 is supported by this hypothesis on the shift position of the earth’s surface.

The mid-ocean ridge is the region where new oceanic crust is created. The oceanic crust is composed of rocks that move away from the ridge as new crust is being formed. The formation of the new crust is due to the rising of the molten material (magma) from the mantle by convection current. When the molten magma reaches the oceanic crust, it cools and pushes away the existing rocks from the ridge equally in both directions.

A younger oceanic crust is then formed, causing the spread of the ocean floor. The new rock is dense but not as dense as the old rock that moves away from the ridge. As the rock moves, further, it becomes colder and denser until it reaches an ocean trench or continues spreading.

It is believed that the successive movement of the rocks from the ridge progressively increases the ocean depth and have greater depths in the ocean trenches. Seafloor spreading leads to the renewal of the ocean floor in every 200 million years, a period of time for building a mid-ocean ridge, moving away across the ocean and subduction into a trench.

Capacitor 1 has a plate area of 1.5 cm² and an electric field between its plates of 2000 V/m and Capacitor 2 has a plate area of 0.7 cm² and an electric field of 1500 V/m.

Therefore, the total charge coming out of the power supply can be calculated by using the following formula:

Q = C × V,

where Q is the total charge coming out of the power supply.

C is the capacitance of the capacitors.

V is the voltage of the capacitors.

The capacitance of a parallel plate capacitor can be calculated by using the following formula:

C = εA/d,

where C is the capacitance of the capacitor.

ε is the permittivity of air.

A is the area of the capacitor plates.

d is the distance between the plates of the capacitor.

let's calculate the capacitance of the capacitors:

For capacitor 1:

ε = ε₀ = 8.85 × 10⁻¹² F/m²

A = 1.5 cm² = 1.5 × 10⁻⁴ m²d = ?

E = 2000 V/mQ = CV

C = εA/dC₁ = ε₀A/d

C₁ = ε₀A/E₁

C₁ = ε₀A/(V/d)

C₁ = (ε₀A/d) × V⁻¹

C₁ = ε₀A₁/E₁

C₁ = (8.85 × 10⁻¹² F/m²)(1.5 × 10⁻⁴ m²)/(2000 V/m)

C₁ = 6.63 × 10⁻¹⁰ F

For capacitor 2:

ε = ε₀ = 8.85 × 10⁻¹² F/m²

A = 0.7 cm² = 0.7 × 10⁻⁴ m²

d = E = 1500 V/m

Q = CV

C = εA/d

C₂ = ε₀A/d

C₂ = ε₀A/E₂

C₂ = (8.85 × 10⁻¹² F/m²)(0.7 × 10⁻⁴ m²)/(1500 V/m)

C₂ = 3.95 × 10⁻¹¹ F

Total charge coming out of the power supply: Q = C₁V + C₂VQ = (6.63 × 10⁻¹⁰ F)(12 V) + (3.95 × 10⁻¹¹ F)(12 V)Q = 8.16 × 10⁻⁹ C. Therefore, the total charge coming out of the power supply is 8.16 × 10⁻⁹ C.

we can plug in the values into the formula for intensity ,The intensity of the laser is approximately 3.377 x 10⁷ W/m².

To find the intensity of the laser, we can use the formula:

Intensity = Power / Area

First, we need to calculate the area of the laser beam. The formula to find the area of a circle is:

Area = π x (radius²)

In this case, the radius of the laser beam is given as 0.469 mm. We need to convert it to meters for consistent units:

0.469 mm = 0.469 x 10⁻³ m = 0.000469 m

Now, we can calculate the area:

Area = π x (0.000469)² = 6.8935 x 10⁻⁷ m²

Next, we can plug in the values into the formula for intensity:

Intensity = 23.3 W / (6.8935 x 10⁻⁷ m²)

Calculating this expression, we find:

Intensity ≈ 3.377 x 10⁷  W/m²

Therefore, the intensity of the laser is approximately 3.377 x 10⁷  W/m².

Conclusion : The intensity of the laser is approximately 3.377 x 10⁷ W/m².
