Answer:
decreases
Explanation:
on each collision, the electrons that make up x-rays get absorbed.
fusion is when solid changes it's state to liquid
and vaporization is when liquid changes it's state to gas
so the difference between fusion and vaporization is the state
Answer:
Inversely proportional
Explanation:
The amplitude and frequency of a wave have an inverse connection, with the amplitude being inversely proportional to the frequency. As the frequency rises, the amplitude falls. As the frequency decreases, the amplitude increases.
Answer:
V = 0.9 m/s
Explanation:
The parameters given are:
Initial velocity U = 6.4 m/s
Time t = 0.64s
Height h = 2.05 m
To find the final velocity, let us use third equation of motion
V^2 = U^2 - 2gH
Since the ball is going upward, g will be negative
Substitute all the parameters into the formula
V^2 = 6.4^2 - 2 × 9.8 × 2.05
V^2 = 40.96 - 40.18
V^2 = 0.78
V = sqrt( 0.78)
V = 0.883 m/ s
V = 0.9 m/ s approximately
