Answer:
6.9%
Explanation:
We are given that
Distance between Earth and Moon=d=
m
Radius of Earth=r=
a.Initially gravitational pull
.....(1)
After changing
Gravitational pull
.....(2)
Equation (2) divided by equation (1)
Increases in gravitational pull=
%
Velocity.
I hope this helps! :)
Answer:
6N
Explanation:
Given parameters:
Pressure applied by the woman = 300N/m²
Area = 0.02m²
Unknown:
Force applied = ?
Solution:
Pressure is the force per unit area on a body
Pressure = 
Force = Pressure x area
Force = 300 x 0.02 = 6N
Answer:
As the liquid cools down, the amount of potential energy is reduced and the molecules start to move slower. When the water temperature reaches around 0°C, the molecules stick together and form a solid – ice
The "stuff" (molecules) in water is more tightly packed than in ice, so water has greater density than ice. Don't let the fact that ice is a solid fool you! As water freezes it expands. So, ice has more volume (it takes up more space, but has less density) than water
