A 10 kg block has the following dimensions: L = 80 cm
W = 5 cm
Ht. = 20 cm

How much pressure does it exert when it is laying on its L and W side?

How much pressure does it exert when it is laying on its L and Ht. side?

How much pressure does it exert when it is laying on its W and Ht. side?

Where do magnetic lines of force enter earth?

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?

What caused magnetic fields? what happens if you keep breaking a magnet in two until you reach a single atom?
