A bungee jumper dives from a bridge. At a point near the bottom of his dive, the forces acting on him are: gravity: 700 N downwards
spring force: 850 N upwards
air resistance: 60 N upwards
Showing your working, calculate:

the net force (strength and direction) acting on him
his acceleration, given that his mass is 70 kg

Which two objects have the greatest gravitational force acting between them

Aphoton is absorbed by an electron that is in the n = 3 state of a hydrogen atom, causing the hydrogen atom to become ionized. very far away from the nucleus, the released electron has a velocity of 750,000 m/s. what was the wavelength of the absorbed photon?

Abag of potato chips contains 2.00 l of air when it is sealed at sea level at a pressure of 1.00 atm and a temperature of 20.0 deg c. what will be the volume of the air in the bag if you take it with you, still sealed, to the mountains where the temperature is 7.00 deg c and atmospheric pressure is 70.0 kpa? assume that the bag behaves like a balloon and that the air in the bag is in thermal equilibrium with the outside air.
