12 Rajiv made a model of a boat. When he places it in water, it sinks. According to Archimedes' principle, why does the boat sink?
A The boat is too small.
B The buoyant force is less than the boat's weight.
C The buoyant force is equal to the boat's weight.
D The buoyant force is greater than the boat's weight.

Describe the path of the electric current through a circuit?

The man of mass m1 and the woman of mass m2 are standing on opposite ends of the platform of mass m0 which moves with negligible friction and is initially at rest with s = 0. the man and woman begin to approach each other. derive an expression for the displacement s of the platform when the two meet in terms of the displacement x1 of the man relative to the platform.

Amaterial that provides resistance to the flow of electric current is called a(an) (1 points)
