To increase the acceleration due to gravity, we will place the new station in a shorter radius which is 1.2 RE.
<h3>What is acceleration due to gravity?</h3>
- This is free fall of an object under the influence of gravitational pull.
The acceleration due to gravity of the new station due to Earth's gravity is calculated as follows;

where;
- g is the acceleration due to gravity
- G is gravitational constant
- M is the mass of the earth
- R is the radius of the earth
To increase the acceleration due to gravity, the radius of the earth must be decreased. Thus, we will place the new station in a shorter radius which is 1.2 RE.

Answer:8.1 m
Explanation:
Given
ball is launched from height of 3 m
initial velocity 
considering the ball is thrown vertically upward
Using 
where,
u=initial velocity
v=final Velocity
a=acceleration
s=distance
At maximum height final velocity will be zero



Therefore maximum height w.r.t ground is 
Answer:
Mass of the object or earth
Answer:
A. the wave speed v and Wavelength
Explanation:
Given that
Mass density per unit length=μ
Frequency = f
The velocity V given as


T=Tension
V=Velocity
V= f λ
λ=Wavelength
Therefore to find the tension ,only wavelength and speed is required.
The answer is A.
The distance traveled per unit time is called speed.
