Answer:
<h2>Person A will hit a distance father</h2>
Explanation:
Based on the fact that the velocity of person A is more than that of person B, that is from the question, person A has a velocity of 2m/s and person B has a velocity of 1m/s, this clearly shows that person A has the tendency to hit a distance farther from the cliff than person B.
Answer:
The ping pong ball is hollow.
Explanation:
Since a ping pong ball, unlike the golf ball, is only filled with air, it is less dense. Air is notably LESS dense than solids, which is what comprises the inside of a golf ball.
Physics is a very important part of Architecture. It helps you to understand how forces work on things that you build, so that they don't collapse. So yes, you do.
Answer:
Option a.
Total area of the cells to generate 6.7 kW, A = 61.4 
Given:
The efficiency of the cell, 
= 9.1%
Power generated by the cells, P = 6.7 kW
Intensity of light, I = 1200 W/
Solution:
Using the formula for intensity of light, I = 
rearranging the above formula for Area, A:
Area, A = 
Now, putting values in the above formula:
Area, A = 
Area, A = 61.355 ≈ 61.4
Yes! Although the object has potential energy, the object is not moving and therefore has no speed. :)
