Answer:
2. decreasing the distance of the space shuttle from Earth
Explanation:
To increase the gravitational force on a space shuttle, it is a good thing to decrease the distance of the space shuttle from the earth.
This is based on the Newton's law of universal gravitation which states that "the gravitational force between two bodies is a directly proportional to the product of their masses and inversely proportional to the square of the distance between them".
Mathematically;
F = 
G is the universal gravitation constant, it cannot be changed
m is the mass of the body
r is the distance
Since the distance is inversely proportional, is we reduce it, the value of the gravitational force will increase.
Answer:
Explanation:
To explain this problem, we need to broach over the concept of pressure.
Pressure is the force applied per unit area on a body.
Pressure = 
We see that the higher the force, the higher the pressure applied. Pressure is directly proportional to force.
Area shares an inverse relationship with pressure. The higher the pressure the lower the area and vice versa.
A high-heeled show shoe has a very small surface area compared to the surface of snowshoes which are larger.
For the same weight which is the downward force of the woman, the high-heeled shoe will have a higher pressure compared to the snow shoe.
The woman works effortlessly over soft snow without sinking in because the snow shoe generates a lower pressure compared to the heeled shoe
The magnitude of the tension is the length of the sum of the two tension vectors. T=√(100²+40²)=1700N
The force equation is mass = force divided by acceleration.
300 = F / 2, six hundred divided by two equals three hundred so that's your answer.
The force is 600 Newtons
