Explanation:
Efficiency is the ratio of energy out to energy in.
e = Eout / Ein
0.52 = 800 J / Ein
Ein ≈ 1538 J
Round as needed.
C.
<span>Each atom has 19 proton
</span> the atomic number is the same as protons
Given :
You fire a paintball from a paintball gun straight up into the air at 25.0 m/s.
To Find :
What is the ball velocity at the higher point that the ball reaches.
Solution :
We know, when ball is moving upward acceleration due to gravity is applied downward.
So, the ball will decelerate and when ball reaches maximum height its velocity will become zero.
Therefore, ball velocity is 0 m/s at maximum height.
Hence, this is the required solution.
Since you are looking at a right fringe, the answer is all
the time a multiple of the wavelength for the reason that the light makes
constructive intrusion. If you are looking at the center (zeroth) fringe, the
difference is (450)(0) = 0. For the first maximum, the difference is 450 nm.
For the second, it is 450 x 2 = 900 nm. Basically, for the nth maxima, the
difference is 450n.
