Answer: trial 3
Explanation:
impulse equals force x time so for each trial it would be a force which is 500 x 8 individual time trial 3 has the highest time which would equal the highest impulse.
500 x .45 = 225
Darker colors attract heat more so maybe u could do some sort of experiment that finds out which color attracts heat the most.
Answer:
Option (b)
Explanation:
Let the ball takes time t to reach the maximum height. The final velocity at maximum height is zero.
Use I equation of motion, we get
V = u + gt
0 = 3 - 9.8 x t
t = 0.306 s
As the air friction is negligible, so the ball takes same time to reach the hand of boy. Thus the time taken by the ball in air is
T = 2 t = 2 x 0.306 = 0.61 s
The molecule that trap's the sun's energy is chlorophyll.
