Answer:
The atmosphere exerts pressure of about 10 power 5 and Nm power-2 or 760 mm of HG at sea level is known as standard atmospheric pressure
Newton's law of universal gravitation:
F = GMm/r²
F = gravitational force, G = gravitational constant, M and m are the masses, r = distance between the masses
Given values:
F = 4.24×10⁻¹⁰N, G = 6.67×10⁻¹¹Nm²kg⁻², M = m = 29kg
Plug in and solve for r:
4.24×10⁻¹⁰ = 6.67×10⁻¹¹(29)(29)/r²
r = 11.5m
Answer:
6.48 m/s
Explanation:
We are given that
Mass,M=2 kg
Radius,R=0.25 m
Height,h=3 m
Moment of inertia of solid sphere=
