Answers

Answer 1

The centripetal acceleration of the ball been whirled in a circular path is 6m/s².

Hence, Option D) 6m/s² is the

Given the data in the question:

Mass of ball; [tex]m = 0.25kg[/tex]Length of string or radius; [tex]r = 1.5m[/tex]Speed; [tex]v = 3m/s[/tex]

Centripetal acceleration is the acceleration of a particle moving in a circular path. It is expressed as:

[tex]a_c = \frac{v^2}{r}[/tex]

Where [tex]a_c[/tex] is the Centripetal acceleration, v is the speed of the motion and r is the length of the string or radius of the circular pattern.

We substitute our given values into the equation

[tex]a_c = \frac{(3m/s)^2}{1.5m}\\\\a_c = \frac{9m^2/s^2}{1.5m}\\\\a_c = 6m/s^2[/tex]

The centripetal acceleration of the ball been whirled in a circular path is 6m/s².

Hence, Option D) 6m/s² is the correct answer.

Weight loss for a fat body does not make a sense of healthy habits. The scale should just be one method of monitoring her overall health.

What are healthy habits?

Healthy habits include good food habits, regular exercising, personal hygiene and positive mind. These all factors affecting our health and it not just our weight.

Body weight can be controlled up to a limit by healthy habits and and controlled food. However, the some people might have a nature of fatty body or skelt irrespective of their habits. In such cases people no need to worry on their health by just looking on their weight.

Answers

Answer:

A snowmobile is used to pull two sleds across the ice. The mass of the snowmobile and the rider is 320 kg. The mass of the first sled behind the snowmobile is 120 kg and the mass of the second sled is 140 kg. The ground exerts a force of 1500 N [forward] on the snowmobile. The coefficient of kinetic friction for the sleds on ice is 0.15. Assume that no other frictional forces act on the snowmobile. Calculate the acceleration of the snowmobile and the sleds.

Explanation:

A snowmobile is used to pull two sleds across the ice. The mass of the snowmobile and the rider is 320 kg. The mass of the first sled behind the snowmobile is 120 kg and the mass of the second sled is 140 kg. The ground exerts a force of 1500 N [forward] on the snowmobile. The coefficient of kinetic friction for the sleds on ice is 0.15. Assume that no other frictional forces act on the snowmobile. Calculate the acceleration of the snowmobile and the sleds.

The acceleration of the snowmobile and the sleds is 1.08ms⁻².

What is acceleration?

Acceleration exists as the rate of change of velocity. Usually, acceleration indicates the speed exists changing, but not always. When an object moves in a circular path at a constant speed, it stands still accelerating, because the direction of its velocity exists altering.

Given:

Mass of the snowmobile and the rider= 320 kg

Mass of the first sled= 120kg

Mass of the second sled= 140kg

Forward force by ground= 1500N

The coefficient of kinetic friction= 0.15

To find:

The acceleration of the snowmobile and the sleds

Solution:

Considering the whole snowmobile and sleds in a single system, the equation for acceleration is:

Forward force - frictional force= (320+120+140) a

Frictional force= Normal reaction on the system X coefficient of kinetic friction

= (320+120+140)g X 0.15

= 870N

Substituting the value in the equation,

1500 - 870 = 580 a

or a = 1.08ms⁻²

Hence, The acceleration of the snowmobile and the sleds is 1.08ms⁻².

A stealth bomber is moving at 600 km/h west and travels to a top velocity of 1,010 km/h west in 4 minutes.
What is the stealth bomber's acceleration in m/s2?

Answers

Answer:

102.5 km/h

Explanation:

The stealth bomber's acceleration is 0.4745 m/s².

The stealth bomber's acceleration can be calculated using the following equation:

acceleration = (final velocity - initial velocity) / time

In this case, the initial velocity is 600 km/h and the final velocity is 1,010 km/h. The time is 4 minutes, which is equal to 240 seconds.

acceleration = (1010 km/h - 600 km/h) / 240 s

= 0.4745 m/s²

Therefore, the stealth bomber's acceleration is 0.4745 m/s².

In words, the stealth bomber's acceleration is 0.4745 meters per second squared. This means that the stealth bomber is increasing its velocity by 0.4745 meters per second every second.

The stealth bomber's acceleration is relatively high because it is accelerating from a speed of 600 km/h to a speed of 1,010 km/h in a short amount of time. The stealth bomber's engines must be very powerful to be able to accelerate the bomber at such a rate.

A Ferris wheel rotates 12 times on for each ride. A passenger is 5 meters from the center of the wheel. The ride takes 10 minutes to complete. What is the angular speed (in radians/second) of the passenger?

The angular speed of the passenger in radians per second is 0.126 rad/s.

The given parameters;

number of turns of the wheel, N = 12 position of the passenger from the center of the wheel, r = 5 mtime of motion, t = 10 minutes, = 600 s

The angular speed of the passenger in radians per second is calculated as follows;

[tex]\omega = \frac{2\pi N}{T} \\\\\omega = \frac{2\pi \times 12 \ rad}{600 \ s} \\\\\omega = 0.126 \ rad/s[/tex]

Find the instantaneous velocity at 8.5s

Answers

When looking at a displacement-time graph, automatically you should realize that the slope is the instantaneous velocity at a specific point. That is, if x increases from 0 to 1 in 2 seconds, the slope would be the change in x divided by the change in time, so (1-0)/2 = 1/2.

As for your problem, we’re looking at when t=8.5s. At this point in the graph, we see a slope that starts at t=8 and ends at t=9, for the change in t of (9-8)=1 second. As for the change in x, we see it goes from -2 to 0 in this time for a change in x of (0-(-2))=2 (remember that a change in a variable is the final number minus the initial number). Therefore, the change in x over the change in time when t=8.5 seconds is 2/1 or just 2. So the instantaneous velocity at t=8.5 is 2m/s.

. An astronomer needs to measure the distance to a globular cluster of stars that is part of the Milky Way Galaxy. What method should she try to use to find the distance?

Answers

The method the astronomer needs to find the distance is the hubble law.

The hubble law states that galaxies are moving away from at earth at speeds proportional to their distance.

The hubble law is expressed mathematically as v = H₀d where v = recessional speed, H₀ = Hubble constant and d = distance of galaxy from earth.

The recessional speed of the galaxy is found from the redshift of the light emitted from the galaxy.

Since we are dealing with a globular cluster of stars, the recessional speed is found from the redshift of the light emitted from the globular cluster of stars.

If we determine the recessional speed, we can then determine the distance of the globular cluster of stars by making the distance subject of the formula in the equation.

So, d = v/H₀

So, the method the astronomer needs to find the distance is the hubble law.
