Answer:
When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.Explanation:
Answer:
The correct option is (d). "3x stronger".
Explanation:
The force between two charged particle is given by :

If one charge is tripled, 
New force will be :

It means if one of the charges were to triple in strength, then the force will become 3 times of the initial force.
Answer:
602.27 kg
Explanation:
The computation of the largest mass of cargo the balloon can lift is shown below:-
Volume of helium inside the ballon= (4 ÷ 3) × π × r^3
= (4 ÷ 3) × 3.14 × 6.953
= 1406.19 m3
Mass the balloon can carry = volume × (density of air-density of helium)
= 1406.19 × (1.29-0.179)
= 1562.27 kg
Mass of cargo it can carry = Mass it can carry - Mass of structure
= 1562.27 - 960
= 602.27 kg
Impulse = change in momentum
J = mΔv = (65.1 kg)(1.82 m/s) = 118.5 kg-m/s
the floor exerts the normal force, which is equal to the player's weight
N = W = mg = (65.1 kg)(9.8 m/s²)
Impulse = average force * time applied
118.5 kg-m/s = F (0.450 s)
The answer is 111.
Using Newton's Second Law, F=ma, plugging known values in we get:
F = (79kg)(1.4m/s^2) = 110.6N ≈ 111N
