Answer:
The surface gravity is inversely proportional to the square of the radius of the planet
Explanation:
The gravity at the surface of a planet is given by:
where
G is the gravitational constant
M is the mass of the planet
R is the radius of the planet
We see from the formula that the surface gravity is inversely proportional to the square of the radius of the planet, R.
At the Earth's surface, the value of the surface gravity is approximately 9.81 m/s^2.

Explanation:
Given
Mass of monkey A=20lb
Mass of monkey B=26lb
Mass of monkey C=25lb
acceleration of monkey A=
acceleration of monkey B=0
acceleration of monkey C=
Force Due to monkey A
Force Due to monkey A
Force Due to monkey A
In addition to it Weights of monkeys will be acting downwards therefore net Downwards force is balanced by tension
T=
Okay, so the density of water is 1g/cm3. In order for the cube to float, it has to be less than 1, and it will sink if it is more than 1 g/cm3. Use a triple beam balance to weigh the cube, looking at the metric ruler on the balance. Then, if the cube's density is more than 1, then you know it will float. If the density is less than 1, you know it will sink.
hope this helps, and I didn't know how to use the word "metric ruler"
Answer:
4 TIMES
Explanation:
As centripetal acceleration has formula a =v^2/r. as r is constant so a is directly proportional to square of speed so square of 2 is 4 hence 4 times
