Physics
1 answer:
xxMikexx [17]3 years ago
8 0

Answer:

<h2>The answer is 9 J</h2>

Explanation:

The kinetic energy of an object can be found by using the formula

KE =  \frac{1}{2} m {v}^{2}  \\

where

m is the mass

v is the velocity

From the question

m = 80 g = 0.08 kg

v = 15 m/s

We have

KE =  \frac{1}{2}  \times 0.08 \times  {15}^{2}  \\  = 0.04 \times 225

We have the final answer as

<h3>9 J</h3>

Hope this helps you

A uniform disk a uniform hoop and a uniform sphere are released at the same time at the top of an inclined ramp. They all roll w
lara [203]

Answer:

D. The sphere the disk and the hoop

Explanation:

This is because the sphere has inertial of

2/5mR²

Disk 1/2mR²

Hope mR²

So these are moment of inertial which is resistance or opposition to rotation so since the sphere has a smaller moment to inertial it will move faster and reach the ground first then the disk then the hoop in that order

<span>The choices can be found elsewhere and as follows:

</span><span>a. they are so small that they stay close to the ground due to the attractive properties of charged soil particles.

b. they are easily carried by the wind.

c. they easily dissolve in liquid droplets.

d. it is easier for then to roll along the small crevices in the ground.</span><span>

</span>I think the correct answer from the choices listed above is option B. Only the smallest particles of soil can be displaced by suspension because they are so small that they are easily carried by the wind. Hope this answers the question. Have a nice day. Feel free to ask more questions.

VashaNatasha [74]

Answer:

a) Your player

b) Observer's player

c) Each measures their own first

Explanation:

Because given problem is having relative velocity to each other. The person sitting on the train is moving with a very high speed relative to the person standing next to the track.

In this case, the clock situated in the train will be running slow with respect to the stationary frame of reference
