Answer:

C- it decrease from 85 J to 76 J because it has 85 J mechanical energy. The pulley decreases from 12 J to 9 J which means it lowers by 12. And it lowers by 3.

Explanation:

That's the answer.

A constant unbalanced force is applied to an object for a period of time. Which graph best represents the acceleration of the ob
balu736 [363]

Answer:

Here is an image attached with similar questions.

The correct answer is D where acceleration is function of time.

Explanation:

The force acting on the object is constant.

There is no change in the application of forces.

And we know that Force is the product of acceleration and masses.

Newtons second law: F=m\times a

Regarding mass we know that it can neither be created nor destroyed.

So in F=m \times a we have two constant terms, constant divided by constant will give the same result as a=\frac{Force}{mass}

There is no change in acceleration (a) with respect to time (t).

So the most appropriate graph where time (t) is changing on x-axis but acceleration doesn't changes is D.

The graph will be similar to y=any\ constant and will be horizontal to the x-axis.

Option D depicts the same.
