Answer:
Explanation:
Given that:
- mass of 1 skier,
- inclination of hill,
- length of inclined slope,
- time taken to reach the top of hill,
- coefficient of friction,
<em>Now, force normal to the inclined plane:</em>
<em>Frictional force:</em>
<em>The component of weight along the inclined plane:</em>
<em>Now the total force required along the inclination to move at the top of hill:</em>
<em>Hence the work done:</em>
<em>Now power:</em>
<u>So, power required for 30 such bodies:</u>
The abundance of Thorium is more than that of uranium, in nature of course.
Answer:
<h2>The answer is 25 J</h2>
Explanation:
The kinetic energy of an object can be found by using the formula
m is the mass
v is the velocity
From the question we have
We have the final answer as
<h3>25 J</h3>
