Explanation:

Answer:

The scale reading at the pole is higher. The difference is 8.019 N.

Explanation:

The centrifugal force of the equator is the same as the centrifugal force of the Earth itself. On the other hand, the centrifugal force on the poles are zero, since they are not spinning in the way the equator is. The centrifugal force on a body at the equator is 0.034 m/s^2 times the mass of the body. The centrifugal force at the poles is zero. Therefore, the total weight of the man at sea level at the equator (gravity minus centrifugal force) is 9.764 m/s^2 times his mass, whereas his weight is 9.863 m/s^2 times his mass at the poles. Using simple multiplication, I figured out his weight at the north pole is 798.903 N, and his weight at the equator is 790.884 N. The difference of these two numbers is 8.019 N.

Hope this helps!

The location where the weight of a person will be more is required.

The scale at the pole has a higher reading.

The difference in weight is 4.212 N.

m = Mass of man = 81 kg

The acceleration due to gravity on the poles is \(g_p=9.832\ \text{m/s}^2\)

The acceleration due to gravity on the equator is \(g_e=9.78\ \text{m/s}^2\)

Gravitational acceleration is given by

\(g=\dfrac{GM}{R^2}\)

where,

M = Mass of Earth

G = Gravitational constant

R = Radius

The Earth in not a perfect sphere it is wider at the equator than at the poles.

As \(R\) increases, the value of  \(g\) decreases.

Weight of the person at the north pole

\(w_p=mg_p\\\Rightarrow w_p=81\times 9.832=796.392\ \text{N}\)

Weight of the person at the Equator

\(w_e=mg_e\\\Rightarrow w_e=81\times 9.78=792.18\ \text{N}\)

The difference in the weight is \(796.392-792.18=4.212\ \text{N}\)

Answer:

Explanation:

Pressure on the hydraulic system is expressed as;

Pressure = Force/Area

Given

Force on the fluid = 400N

Area = 0.001m²

Pressure in the fluid = 400/0.001

Pressure in the fluid = 400,000N/m²

1N/m² = 0.001kPa

400,000N/m² = x

x = 400,000 × 0.001

x = 400kPa

Hence the pressure in kPa is 400kPa

b) Using the formula;

Pa = Pb

Fa/Aa = Fb/Ab

Pa = Fb/Ab

Fb = PaAb

Fb = 400,000(0.2)

Fb = 80,000N

Hence the magnitude of the force exerted on the load bearing piston by the hydraulic fluid is 80,000N

(a) The work done by the 150 N force is 877.5 Joules.

(b) The coefficient of kinetic friction between the crate and the surface is approximately 0.437.

To answer this problem, we must take into account the work done by the applied force as well as the work done by friction.

(a) The applied force's work may be estimated using the following formula:

Work = Force * Distance * cos(theta)

where the force is 150 N and the distance is 5.85 m. Since the force is applied horizontally and the displacement is also horizontal, the angle theta between them is 0 degrees, and the cosine of 0 degrees is 1.

As a result, the applied force's work is:

Work = 150 N * 5.85 m * cos(0) = 877.5 J

So, the work done by the 150 N force is 877.5 Joules.

(b) Frictional work is equal to the force of friction multiplied by the distance. The work done by friction is identical in amount but opposite in direction to the work done by the applied force since the crate travels at a constant speed.

The frictional work may be estimated using the following formula:

Work = Force of Friction * Distance * cos(theta)

The net force applied on the crate is zero since it is travelling at a constant pace. As a result, the friction force must be equal to the applied force, which is 150 N.

Thus, the work done by friction is:

Work = 150 N * 5.85 m * cos(180) = -877.5 J

Since the work done by friction is negative, it indicates that the direction of the frictional force is opposite to the direction of motion.

The coefficient of kinetic friction may be calculated using the following equation:

Friction Force = Kinetic Friction Coefficient * Normal Force

The normal force equals the crate's weight, which may be computed as:

Normal Force = mass * gravity

where the mass is 35.0 kg and the acceleration due to gravity is approximately 9.8 m/s^2.

Normal Force = 35.0 kg * 9.8 m/s^2 = 343 N

Now, we can rearrange the equation for the force of friction to solve for the coefficient of kinetic friction:

Force of Friction = coefficient of kinetic friction * Normal Force

150 N = coefficient of kinetic friction * 343 N

coefficient of kinetic friction = 150 N / 343 N ≈ 0.437

As a result, the kinetic friction coefficient between the container and the surface is roughly 0.437.

In summary, the work done by the 150 N force is 877.5 Joules, and the coefficient of kinetic friction between the crate and the surface is approximately 0.437.

Explanation:

Check out the Periodic Table attached here. The Carbon family is the vertical group starting with Carbon, Group 14. Nonmetals are in green, which element there is a nonmetal?

The concept of this question can be well understood by listing out the parameters given.

The purpose is to determine the spring constant.

Let us assume that the two blocks are Block A and Block B.

At point A on block A, the initial velocity on the block is zero

i.e. u = 0

We want to determine the time it requires for Block A to reach the table. The can be achieved by using the second equation of motion which can be expressed by using the formula.

\(\mathsf{S = ut + \dfrac{1}{2}gt^2}\)

From the above formula,

The distance (S) = 30 cm; we need to convert the unit to meter (m).

The acceleration (g) due to gravity = 9.8 m/s²

∴

inputting the values into the equation above, we have;

\(\mathsf{0.3 = (0)t + \dfrac{1}{2}*(9.80)*(t^2)}\)

\(\mathsf{0.3 = \dfrac{1}{2}*(9.80)*(t^2)}\)

\(\mathsf{0.3 =4.9*(t^2)}\)

By dividing both sides by 4.9, we have:

\(\mathsf{t^2 = \dfrac{0.3}{4.9}}\)

\(\mathsf{t^2 = 0.0612}\)

\(\mathsf{t = \sqrt{0.0612}}\)

\(\mathbf{t =0.247 \ seconds}\)

However, block B comes to an instantaneous rest on point C. This is achieved by the dropping of the block on the spring. During this process, the spring is compressed and it bounces back to oscillate in that manner. The required time needed to get to this point C is half the period, this will eventually lead to the bouncing back of the block with another half of the period, thereby completing a movement of one period.

By applying the equation of the time period of a simple harmonic motion.

\(\mathbf{T = 2 \pi \sqrt{\dfrac{m}{k}}}\)

where the relation between time (t) and period (T) is:

\(\mathsf{t = \dfrac{T}{2}}\)

T = 2t

T = 2(0.247)

T = 0.494 seconds

\(\mathbf{T = 2 \pi \sqrt{\dfrac{m}{k}}}\)

By making the spring constant (k) the subject of the formula:

\(\mathbf{\dfrac{T}{2 \pi } = \sqrt{ \dfrac{m}{k}}}\)

\(\Big(\dfrac{T}{2 \pi }\Big)^2 = { \dfrac{m}{k}\)

\(\dfrac{T^2}{(2 \pi)^2 }= { \dfrac{m}{k}\)

\(\mathsf{ T^2 *k = 2 \pi^2*m} \\ \\ \mathsf{ k = \dfrac{2 \pi^2*m}{T^2}}\)

\(\mathsf{ k =\Big( \dfrac{(2 \pi)^2*(51 \times 10^{-3})}{(0.494)^2} \Big) N/m}\)

\(\mathbf{ k =8.25 \ N/m}\)

Therefore, we can conclude that the spring constant between the two 51 g blocks held at a distance 30 cm above a table as a result of instantaneous rest caused by the compression of the spring is 8.25 N/m.

1) 90.9m

Explanation:

From the question, we are given the following;

Speed v = 30m/s

Maximum height H = 45m

Required;

Time

Using the equation of motion S = ut + 1/2gt²

Substitute;

45= 30t + 1/2(9.8)t²

45 = 30t + 4.9t²

4.9t² + 30t - 45 = 0

Factorize;

t = -30 ±√30²-4(-45)(4.9)/2(4.9)

t = -30 ±√900+882/9.8

t = -30 ±42.21/9.8

t = -30 + 42.21/9.8

t = 12.21/9.8

t = 1.25secs

Hence the ball spent 1.25secs in air.

i) To get the horizontal distance, we will use the formula;

R = U√2H/g

R = 30√2(45)/9.8

R = 30√90/9.8

R = 30√9.18

R = 30(3.03)

R = 90.9m

Hence the horizontal distance is 90.9m

After 0.100 s, the cat would be 0.049 m below its initial position, with a velocity of 0.98 m/s. After 0.200 s, the cat would be 0.196 m below its initial position, with a velocity of 1.96 m/s. Finally, after 0.300 s, the cat would be  0.441 m below its initial position, with a velocity of approximately 2.94 m/s.

To calculate the position and velocity of the sleeping cat after certain time intervals, we need to make some assumptions and use basic principles of physics.

Assuming the cat falls vertically downward due to gravity and ignoring air resistance, we can apply kinematic equations to solve the problem.

(a) Position:

Using the equation for the position of an object in free fall, h = (1/2)gt^2, where h is the height, g is the acceleration due to gravity (approximately 9.8 m/s^2), and t is time, we can determine the position of the cat.

After 0.100 s: h = (1/2)(9.8 m/s^2)(0.100 s)^2 = 0.049 m (approximately)

After 0.200 s: h = (1/2)(9.8 m/s^2)(0.200 s)^2 = 0.196 m (approximately)

After 0.300 s: h = (1/2)(9.8 m/s^2)(0.300 s)^2 = 0.441 m (approximately)

(b) Velocity:

The velocity of the cat can be calculated using the equation v = gt, where v is the velocity and t is time.

After 0.100 s: v = (9.8 m/s^2)(0.100 s) = 0.98 m/s (approximately)

After 0.200 s: v = (9.8 m/s^2)(0.200 s) = 1.96 m/s (approximately)

After 0.300 s: v = (9.8 m/s^2)(0.300 s) = 2.94 m/s (approximately)

Answer:

81.1 m/s

Explanation:

The net force of Jason is T - f = ma where T = thrust = 200 N f = frictional force = μN = μmg where μ = coefficient of kinetic friction of water = 0.10, m = mass of Jason plus skis = 75 kg, g = acceleration due to gravity = 9.8 m/s² and a = Jason's acceleration

So, T - f = ma

T -  μmg  = ma

a = T/m - μg

susbstμituting the values of the varμiables into the equation, we have

a = 200 N/75 kg - 0.1 × 9.8 m/s²

a = 200 N/75 kg - 0.1 × 9.8 m/s²

a = 2.67 m/s² - 0.98 m/s²

a = 1.69 m/s²

Using v = u + at, we find Jason's velocity v where u = initial velocity = 0 m/s (since he starts from rest), a = 1.69 m/s² and t = time = 48 s

So, v = u + at

v = 0 m/s + 1.69 m/s² × 48 s

v = 0 m/s + 81.12 m/s

v = 81.12 m/s

v ≅ 81.1 m/s

So, Jason's top speed is 81.1 m/s

Answer:

The pythagoream theorem

Explanation:

The unit vector in the direction of the resultant of vectors A, B, and C is: (6i - j + 3k) / √46

To find a unit vector in the direction of the resultant of vectors A, B, and C, we need to calculate the sum of these vectors and then normalize the resulting vector.

Given:

Vector A = (2i + 1j - 3k)

Vector B = (i + j + 2k)

Vector C = (3i - 2j + 4k)

To find the resultant vector R, we add these vectors together:

R = A + B + C

= (2i + 1j - 3k) + (i + j + 2k) + (3i - 2j + 4k)

= (2i + i + 3i) + (1j + j - 2j) + (-3k + 2k + 4k)

= 6i - j + 3k

Now, to obtain a unit vector in the direction of R, we divide R by its magnitude:

Magnitude of R = √(6² + (-1)² + 3²)

= √(36 + 1 + 9)

= √46

Unit vector in the direction of R = R / Magnitude of R

= (6i - j + 3k) / √46

Therefore, the unit vector in the direction of the resultant of vectors A, B, and C is:

(6i - j + 3k) / √46

It's important to note that the unit vector represents the direction of the resultant vector, while its magnitude is always 1. By normalizing the resultant vector, we obtain a unit vector that points in the same direction but has a magnitude of 1, providing information solely about the direction of the resultant.
