Answer:
pressure is an affect which occurs when a force is applied on a surface area
Explanation:
its unit are barr,millbarr,torr,mmhg
Answer:
Given that,
Mass of the Earth m
1
=6×10
24
Kg
Mass of the Moon m
2
=7.4×10
22
kg
Distance between the Earth and the Moon d=3.84×10
5
km=3.84×10
8
m
Gravitational Constant G=6.7×10
−11
Nm
2
/kg

Now, by using Newton’s law of gravitation
F=
r

F=
(3.84×10

)
2
6.7×10
−11
×6×10
24
×7.4×10
22
F=
14.8225×10
16
297.48×10
35
F=20.069×10
19
F=20.1×10
19
N
Hence, the gravitational force of attraction is 20.1×10
