How high has a 45 g golf ball been driven if it has a potential energy of 2.06 J?

Answers

Here, U = mgh

We have: m = 45 g = 0.045 Kg
U = 2.06 J, g = 9.8 m/s², h = ?

Substitute the values in the formula:
2.06 = 0.045 × 9.8 × h
2.06 = 0.441 × h
h = 2.06 / 0.441
h = 4.67 m

In short, your final answer would be 4.67 meters

Hope this helps!

PE=mgh
2.06 J = 2.06 kg·m²/s² = (0.045 kg)·(9.8 m/s²)·h
where h is the height the ball has reached
Solve for h:
h = 2.06/(0.045·9.8) = 4.67 to the nearest hundredth
h = 4.67 m

A student pushes a 40-N block across the floor for a distance of 10 m. How much work was done to move the block? Question 3 options: 4 J 40 J 400 J 4,000 J

Answers

Answer:

The work done to move the block is 400 Joules.

Explanation:

It is given that,

Force acting on the block, F = 40 N

The distance covered by the block, d = 10 m

We need to find the work done by the block. The work done by an object is given by :

$W=F* d$

$W=40\ N* 10\ m$

W = 400 Joules

So, the work done to move the block is 400 Joules. Hence, the correct option is (B) "400 J".

40x10=400 J

Work = Force x distance

What material are you most likely to find in the D horizon

Answers

Answer:

The soil is comprised of various layers which are commonly known as the horizons, of which D is also a part of it. The D horizon is not always found. But it sometimes occurs below the B or the C horizon.

The materials that are present in this horizon are not affected by the weathering process. They are comprised of unaffected, raw mineral matter and are very hard and resistant like the parent rock. This layer gives rise to the formation of a much more complex layers that are comprised of numerous mineral matter.

you're most likely to find Bedrock
