It's named like this because the force between charges or electrons is called electrostatic force .
If a coastline has a very unusual shape it's normally caused by either a flood or dam.
hope this helps!
Answer:
b) 4781 N
Explanation:
Because there is a redius do this question is talking about the acceleration force which= mv^2/r
so a=15^2/80=2.8125 m^2/s
so the force will be = m.a
F =1700×2.8125=4781.25 N
Answer:
The change in length is 0.01056 m.
Explanation:
Given that,
Length = 11 m
Temperature = 20°C
Pressure = 1 atm
Boiling temperature = 100°C
We need to calculate the length
Using formula of change in linear expansion


Put the value into the formula



Hence, The change in length is 0.01056 m.
