The escape speed from the moon is much smaller than from earth. True or False
Lisa [10]

Answer:

True

The escape speed from the Moon is much smaller than from Earth.

Explanation:

The escape speed is defined as:

v_{e} = \sqrt{\frac{2GM}{r}}  (1)

Where G is the gravitational constant, M is the mass and r is the radius.

The mass of the Earth is 5.972x10^{24}kg and its radius is 6371000m

Then, replacing those values in equation 1 it is gotten.

v_{e} = \sqrt{\frac{(2)(6.67x10^{-11}N.m^{2}/kg^{2})(5.972x10^{24}kg)}{(6371000m)}}  

v_{e} = 11.18m/s

For the case of the Moon:

v_{e} = \sqrt{\frac{(2)(6.67x10^{-11}N.m^{2}/kg^{2})(7.347x10^{22}Kg)}{(1737000m)}}  

v_{e} = 2.38m/s

Hence, the escape speed from the Moon is much smaller than from Earth.

Since it has a smaller mass and smaller radius compared to that from the Earth.

Explain how the basic units are combined to give the derived units of force, velocity and pressure and work​
Lorico [155]

#Force

\\ \sf\longmapsto Force=Mass\times Acceleration

\\ \sf\longmapsto Force=kg m/s^2

\\ \sf\longmapsto Force=Newton (N)

#Velocity

\\ \sf\longmapsto Velocity=\dfrac{Displacement}{time}

\\ \sf\longmapsto Velocity=m/s

#Work

\\ \sf\longmapsto Work=Force\times Displacement

\\ \sf\longmapsto Work=Nm

\\ \sf\longmapsto Work=Joules(J)
