Answer:solar energy
Explanation:
This is the energy gotten from sunlight to knock off electrons from fee atom.
This panel contains photovoltaic cells
Distance = (1/2) (acceleration) (time)²
1.4m = (0.835 m/s²) (time)²
(time)² = (1.4/0.835) s²
<em>time = 1.295 s</em>
Answer:
Explanation:
Given that,
Number of extra electrons, n = 21749
We need to find the net charge on the metal ball. Let Q is the net charge.
We know that the charge on an electron is 
To find the net charge if there are n number of extra electrons is :
Q = n × q
So, the net charge on the metal ball is 
. Hence, this is the required solution.
To hit the target the crew drop the crate before the plane is directly over the target. It is because <span>because the cargo has forward velocity and therefore before it reaches the ground it travels some distance. The answer is A. Hope it helps. </span>
