Answer:
The speed of the resistive force is 42.426 m/s
Explanation:
Given;
mass of skydiver, m = 75 kg
terminal velocity, 
The resistive force on the skydiver is known as drag force.
Drag force is directly proportional to square of terminal velocity.
Where;
k is a constant
When the new drag force is half of the original drag force;
Therefore, the speed of the resistive force is 42.426 m/s
Answer:
take some sharp mixture of iron spread it from up the magnet you will see the magnetic field of magnet
Then the force of gravity between them would be quadrupled and so on but the gravitational force is inversely proportional to the square of the separation distance between the two interacting objects which makes more separation distance will result in weaker gravitational forces
