cells are the basic unit of all living things
<span>When you apply force to move an
object at a distance, you are applying work. And work is energy in transit. The
answer is letter D. For example, you see a cart at a distance. You observe that
it is not moving. You want to transfer it to your backyard. You apply force to
the cart and observed that the cart is not at the same position as it was
before. You are applying work to the cart by transferring your energy to it.</span>

The minimum value of the coefficient of static friction between the block and the slope is 0.53.
<h3>Minimum coefficient of static friction</h3>
Apply Newton's second law of motion;
F - μFs = 0
μFs = F
where;
- μ is coefficient of static friction
- Fs is frictional force
- F is applied force
μ = F/Fs
μ = F/(mgcosθ)
μ = (250)/(50 x 9.8 x cos15)
μ = 0.53
Thus, the minimum value of the coefficient of static friction between the block and the slope is 0.53.
