Angstrom = 10^-10 m
for nucleus size are used fermi (femtometer 10^-15 m )
B. Some of the ball’s energy is transformed to thermal energy.
Hope this helps you!
Answer: here are 1,000m in a km, so 200km is 200,000m
200,000m/10m/s = 20,000s
Explanation:
<span>Volume of cylinder = pi*r*2*L
As, from the above formula,volume is directly proportional to length,
So, if we increase in length also increases in volume by 0.22%
we know
</span><span>density=<span><span>mass/</span><span>volume
As, density is inversely proportional to volume it means increasing in volume decreases the density by 50.22%
