Answer:
True
The escape speed from the Moon is much smaller than from Earth.
Explanation:
The escape speed is defined as:
(1)
Where G is the gravitational constant, M is the mass and r is the radius.
The mass of the Earth is and its radius is
Then, replacing those values in equation 1 it is gotten.
For the case of the Moon:
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.
Answer: 735 N
Explanation:
Weight is a measure of the gravitational force acting on an object and is directly proportional to the product of the mass
of the body by the acceleration of gravity
:
In the case of our planet Earth, the acceleration due gravity is . So for a man whose mass is
, his weight is:
