On the surface of the earth, weight is calculated by multiplying mass
and gravity.
<span>Because we know the radius of the Earth, we can use the Law of
Universal Gravitation to calculate the mass of the Earth in terms of the
gravitational force on an object (its weight) at the Earth's surface, using the
radius of the Earth as the distance. We also need the Constant of
Proportionality in the Law of Universal Gravitation, G. This value was experimentally determined by Henry
Cavendish in the 18th century to be the extemely small force of 6.67 x 10</span>-11 Newtons
between two objects weighing one kilogram each and separated by one meter.
Cavendish determined this constant by accurately measuring the horizontal force
between metal spheres in an experiment sometimes referred to as "weighing
the earth."
The correct answer between all
the choices given is the third choice or letter C. I am hoping that this answer
has satisfied your query and it will be able to help you in your endeavor, and

Answer:
100 J
Explanation:
Given:
Force acting on the crate is, 
Displacement of the crate is, 
Angle between the direction of force and displacement is, 
Now, work done by a force 'F' causing a displacement 'S' such that the angle between the force and displacement is 
is given as:
Now, plug in 100 N for 'F', 2 m for 'S', and 60° for . This gives,
Therefore, the work done by the force is 100 J.
Assuming that the relationship between spring compression and height is quadratic, 2.25m far will the ball go at the highest setting, compresses the spring 3 cm
<h3>How do you calculate a compression spring's solid height?</h3>
The solid height, h1, of an unground spring is (n+1)d, where n is the number of coils and d is the wire diameter (including platings and coating) in inches. The height, h2, of ground but not squared springs is (n-1)d. The solid height, h3, of ground and squared springs is (n-0.75)d
When a spring is compressed, the potential energy is stored in the mechanical bonds between atoms, which may be thought of as little springs. The spring as a whole cannot decompress until it breaks, but little portions may when they fall off. The majority of the stored energy is used to decompress each little component.
