The answer should be C. :)
Answer:
The value in Newton is 
The value in pounds is 
Explanation:
From the question we are told that
The mass of the spacecraft is 
The distance above the earth is 
Generally the gravitational force with respect to the earth is mathematically represented as
Here 
is the mass of earth with value 
is the radius of the earth with value 
G is the gravitational constant with value 
So
Converting to pounds
Explanation:
Objects at rest and in motion respond to the presence of an external unbalanced force by simple changing their magnitude of motion or position.
We have this knowledge from Newtons first law of motion "a body will remain in a state of rest or continue with uniform motion unless if it is acted upon by an external force".
- When an external force acts on a body at rest, it will change the position of the body or set it motion.
- For a body in motion, an external force can make they come to rest or change the motion of the body
Explanation:
According to International Astronomical union a planet must satisfy the following three conditions-
1. It should orbit around sun(parent star).
2. It should have enough gravity to maintain almost spherical shape.
3. It should have cleared its neighbourhood around its orbit.
Pluto does not fulfill the third criteria and hence it has been re-categorized as dwarf planet.
Answer:
1: toward the normal
2:away from normal
3: red because the index of refraction ( the ratio of the speed of light in a vacuum to the speed of light in a material) is increased for the slower moving waves
