How much force is acting on a certain area

Answer:

v = 190 m/s

Explanation:

Given that,

Initial velocity of a car, u = 10 m/s

Distance, d = 500 m

Time, t = 5 s

We need to find the final velocity of the car. Firstly we can find the acceleration of the car using second equation of motion as follows :

\(d=ut+\dfrac{1}{2}at^2\\\\500=10\times 5+\dfrac{a}{2}\times 5^2\\\\500=50+\dfrac{25a}{2}\\\\450=\dfrac{25a}{2}\\\\a=\dfrac{450\times 2}{25}\\\\a=36\ m/s^2\)

let v is the final velocity. using First equation of motion to find a as follows :

v=u+at

v=10+36(5)

v=190 m/s

So, the final velocity of the car is 190 m/s.

Explanation:

All of the given choices are correct definition of what weight of a substance implies.

Weight is the vertical force on a body due to the gravitational attraction or pull.

  Weight  = mass x acceleration due to gravity

Mass of a body is directly proportional to its weight and so also is the gravity.

Mass is the amount of matter within a substance.

Weight is the force of gravity exerted by a body on another or a surface.

The reason why the weight of a body changes from place to place is mainly due to the gravitational pull

Gravitational acceleration on the newly discovered planet is calculated to be approximately 26.7 m/s².

The acceleration of an object in free fall within a vacuum is known as gravitational acceleration.

As we know, g = G * M / r²

G is the gravitational constant (6.67 x 10⁻¹¹  N*m²/kg²)

M is the mass of the planet

r is the radius of the planet

Plugging in the given values, we get:

g = (6.67 x 10⁻¹¹ N*m²/kg²) * (7.0 x 10²⁴ kg) / (5600 km)²

g = (6.67 x 10^⁻¹¹  N*m²/kg²) * (7.0 x 10²⁴  kg) / (5600 x 1000 m)²

g ≈ 26.7 m/s²

Therefore, the gravitational acceleration on the newly discovered planet is approximately 26.7 m/s².

Explanation:

Hello,

In this case, considering this as a dilution problem, the first step here is to consider that the moles of tetrodotoxin remains the same and just the volumes and concentrations are modified from the initial stock (1) and the required dilution (2):

\(V_1M_1=V_2M_2\)

Whereas V is referred to volume and M to molar concentration, in this case in mM. In such a way, solving the V1 as the volume of the 3-mM solution we obtain:

\(V_1=\frac{V_2M_2}{M_1} \\\\V_1=\frac{6mL*1mM}{3mM} \\\\V_1=2mL\)

It means you need 2 mL of the 3-mM solution.

Answer:

To find the net charge on the sphere using electric flux, we can use the formula:  

Φ = Q/ε0

Where Φ is the electric flux, Q is the charge, and ε0 is the permittivity of free space.  

Given that the electric field 20 cm from the center of the sphere is N/C and points radially inwards, we can use the formula for electric field due to a charged sphere to find the charge on the sphere:

E = kQ/r^2  

Where E is the electric field, k is Coulomb's constant, Q is the charge, and r is the distance from the center of the sphere.  

Substituting the given values, we get:  

20 = (1/4πε0)(Q)/(0.2)^2  

Solving for Q, we get:  

Q = (20)(0.2)^2(4πε0)  

Q = 0.64πε0 C  

Now, substituting this value of Q in the formula for electric flux, we get:  Φ = Q/ε0 = (0.64πε0)/(ε0) = 0.64π C  

Therefore, the net charge on the sphere is 0.64π C.

The average acceleration of the motorcycle over the given distance is approximately 9.39 m/s².

To calculate the average acceleration of the motorcycle, we can use the formula:

Average acceleration = (final velocity - initial velocity) / time

First, let's convert the final velocity from km/h to m/s since the distance is given in meters. We know that 1 km/h is equal to 0.2778 m/s.

Converting the final velocity:

Final velocity = 78 km/h * 0.2778 m/s = 21.67 m/s

Since the motorcycle starts from rest (initial velocity is zero), the formula becomes:

Average acceleration = (21.67 m/s - 0 m/s) / time

To find the time taken to reach this velocity, we need to use the formula for average speed:

Average speed = total distance/time

Rearranging the formula:

time = total distance / average speed

Plugging in the values:

time = 50 m / 21.67 m/s ≈ 2.31 seconds

Now we can calculate the average acceleration:

Average acceleration = (21.67 m/s - 0 m/s) / 2.31 s ≈ 9.39 m/s²

a) The image is attached to this answer

b) The kinetic friction force affects the forward force of the ball.

The force that opposes a rolling ball's motion is called rolling friction. It slows the ball down by acting in the opposite direction to that of the ball's motion. The weight of the ball and the type of the surface are two variables that affect rolling friction.

The force that a surface uses to maintain the weight of an object that is resting on it is known as the normal force. When a ball is rolling, the normal force exerts itself perpendicular to the surface the ball is moving on. It maintains the ball's weight balance and offers the required reaction force for rolling motion.

Answer:

The time for the rock to reach the bottom is 4.02 seconds.

Explanation:

Given;

mass of the rock, m = 5 kg

height of the rock fall, h = 79 meters

The time to drop to the given height is given by;

\(t = \sqrt{\frac{2h}{g} }\)

where;

t is the time to fall to the bottom

g is acceleration due to gravity = 9.8 m/s²

\(t = \sqrt{\frac{2h}{g} } \\\\t = \sqrt{\frac{2*79}{9.8} }\\\\t = 4.02 \ s\)

Therefore, the time for the rock to reach the bottom is 4.02 seconds.

Answer:

 Δt'/ T% = 90.3%

Explanation:

Simple harmonic movement is described by the expression

         x = A cos (wt)

we find the time for the two points of motion

x = - 0.3 A

        -0.3 A = A cos (w t₁)

         w t₁ = cos -1 (-0.3)

remember that angles are in radians

        w t₁ = 1.875 rad

x = 0.3 A

        0.3 A = A cos w t₂

        w t₂ = cos -1 (0.3)

         w t₂ = 1,266 rad

Now let's calculate the time of a complete period

x= -A

        w t₃ = cos⁻¹ (-1)

        w t₃ = π rad

this angle for the forward movement and the same time for the return movement in the oscillation to the same point, which is the definition of period

         T = 2 t₃

         T = 2π / w     s

now we can calculate the fraction of time in the given time interval

        Δt / T = (t₁ -t₂) / T

        Δt / T = (1,875 - 1,266) / 2pi

        Δt / T = 0.0969

This is the fraction for when the mass is from 0 to 0.3, for regions of oscillation of greater amplitude the fraction is

         Δt'/ T = 1 - 0.0969

         Δt '/ T = 0.903

         Δt'/ T% = 90.3%

The normal reactions of the wheel is determined as 13222.22 lb at point F and 21888.89 lb for point E and D.

Free body diagram of the plane is drawn by removing all the supports and replacing with forces. Equilibrium of moment of forces about x-axis is considered and relation between the reaction forces at point D and E is determined. Equilibrium of moment of forces about y-axis is considered and value of the reaction force at point F is determined. Moment of axis (line) is considered to eliminate an unknown force and get equation with other two variables.

After drawing the free body diagram, apply force balance about x-axis:

= ∑Mₓ = 0

= - (R₄ X 14) + (R₅ X14) + (W₂ X 6) - (W₃ X 8) = 0

= (R₅ - R₄) X 14 =  (W₃ X 8) - (W₂ X 6)

= R₅ = R₄

Apply moment balance about y axis,

= ∑Mₙ = 0

= - (R₆ X 27 ) + (W₁ X 7) + (W₂ X 4) + (W₃ X 4) = 0

= R₆ = 13222.22 lb

Next, consider force equilibrium equation.

Write the force equilibrium equation along vertical axis, z-axis;

= ∑F = 0

= R₆ + R₅ + R₄ - (W₁ + W₂ + W₃) = 0

where, R represents reaction and W represents load.

= R₆ + R₅ + R₄ - (W₁ + W₂ + W₃) = 0

The dog's displacement is 27m towards east.

What is displacement?

Displacement is the distance between two points in a given space. It is a vector quantity that measures the difference between the initial and final positions of an object. Displacement is the shortest distance between two points and it is always directed from the initial position to the final position. It is measured in meters, centimeters, or other units of length. Displacement is related to velocity, which is the rate at which an object changes its position over time, and acceleration, which is the rate of change in velocity. Displacement can also be used to measure the progress of a boat, the length of a journey, or the distance between two cities.

The dog starts its journey towards east for 50m and then goes in the opposite direction (west) towards the starting point for 23m. Hence the distance is 50 - 23 = 27.

The initial volume of the liquid is 31.4 cm³. The volume coefficient of thermal expansion of the liquid is 0.002 per degree Celsius. A temperature increase of 109.5°C is needed for the liquid to rise to a height of 49cm.

The initial volume of the liquid can be found using the formula for the volume of a cylinder:

V = πr²h

where r is the radius (half the diameter), h is the height, and π is approximately 3.14. Plugging in the given values, we get:

V = π(0.5 cm)²(40 cm)

V = 31.4 cm³

The volume coefficient of thermal expansion (β) is defined as the fractional change in volume per degree Celsius change in temperature. It can be calculated using the formula:

β = ΔV/(VΔT)

where ΔV is the change in volume, V is the initial volume, and ΔT is the change in temperature. We can rearrange this formula to solve for ΔV:

ΔV = βVΔT

We know that ΔT = -10°C (a decrease of 10°C) and that the height decreased from 40cm to 37cm, or by 3cm. The change in volume can be found using the formula for the volume of a cylinder again, with the new height of 37cm:

ΔV = π(0.5 cm)²(40 cm - 37 cm)

ΔV = 0.59 cm³

Plugging in all the values, we get:

0.59 cm³ = β(31.4 cm³)(-10°C)

β = 0.002

To find the change in temperature needed for the liquid to rise to a height of 49cm, we can use the same formula as before, but solve for ΔT:

ΔT = ΔV/(βV)

We know that ΔV is the difference between the initial volume and the volume at the new height, which is:

ΔV = π(0.5 cm)²(49 cm - 40 cm)

ΔV = 6.86 cm³

Plugging in all the values, we get:

ΔT = 6.86 cm³/(0.002)(31.4 cm³)

ΔT = 109.5°C

Given:

• The initial upward velocity of the cannonball, u = 15.0 m/s

• The initial height of the cannonball, y₀ = 10.0 m

Find:

• The time it takes for the cannonball to reach the ground, t

What we have to find is the time it will take for the cannonball to reach a height of y = 0. First, the cannonball travels upward until it reaches its maximum height. At this point, the ball stops and starts speeding up downwards, so, first, we can find the time it takes for the cannonball to reach its maximum height,

Solving for the time,

Now, knowing that time, we can find what is the ball's maximum height,

Now we have to find how long will it take for the cannonball to reach the ground when the initial velocity is 0 - since it is at its maximum height, and travel 21.48 m in total to the ground,

So, in total the cannonball traveled up for 1.53 seconds until its maximum height and, then, it traveled back down for 2.09 seconds until it reached the ground,

Hence, it takes 3.62 seconds for the cannonball to reach the ground.

Functionalism: According to functionalism, social inequality is necessary for the smooth functioning of society. This means that even if all the world's wealth and assets were equally divided, people's skills, abilities, and efforts would still differ, leading to differences in income and wealth. Moreover, social positions that require more education, training, and skills would still be rewarded more highly than those that require less. Therefore, some people would still be motivated to achieve more than others and occupy higher social positions. Additionally, some people might not want to work hard and would be content with their share, while others might want to invest their share and accumulate more wealth. This would lead to differences in wealth and income over time, leading to the re-emergence of social stratification.

Conflict Theory: According to conflict theory, social inequality is the result of the struggle for power and resources between different social groups. Even if all the world's wealth and assets were equally divided, some people or groups would still try to monopolize the resources and accumulate more wealth and power than others. For example, some people might try to control the means of production, such as land, factories, and capital, while others might try to control the distribution of goods and services, such as markets, transportation, and communication. Moreover, some people might have more social and cultural capital, such as education, networks, and prestige, which would give them an advantage in achieving their goals. Therefore, social stratification would still exist, but in different forms and with different justifications.

Interactionism: According to interactionism, social inequality is the result of the symbolic meanings and interpretations that people attach to wealth, status, and power. Even if all the world's wealth and assets were equally divided, people would still have different attitudes, values, and beliefs about them, which would affect their behavior and interactions. For example, some people might feel more entitled to a higher share of the wealth and assets because of their race, gender, religion, or nationality, while others might feel less entitled or even resentful. Moreover, some people might use their wealth and assets as symbols of their identity, status, and prestige, while others might reject them as meaningless or corrupt. Therefore, social stratification would still exist, but in different symbolic forms and meanings.
