If there is a negligible air resistance, heavy objects fall faster than light objects because there is a stronger gravitational force acting on heavier objects.

The reason why a hot air balloon rises but a balloon of equal size filled with cold air does not rise is

During a collision between a large truck and a small car,

The functioning of cells depends on various elements, such as Na, K, and Ca, that are dissolved in water as ions. These ions move in and out of cells through narrow pores in the cell membrane known as ion channels. Each ion channel, which is formed from a specialized protein molecule, is selective for one type of ion. Measurements with microelectrodes have shown that a 0.30-nm-diameter potassium ion (K+) channel carries a current of 1.80 pA. How many potassium ions pass through if the ion channel opens for 1.0 ms?

Every minute, 120 C of charge flow through this cross section of the wire

Wire 2 is twice the length and has twice the cross-sectional area that of wire 1. What is the ratio R2/R1 of their resistances?

Now use the same graphs to consider a different policy. Suppose a price ceiling of $2 is imposed on the original sellers. However, resales by consumers are legal. The change in total surplus (deadweight loss) of the policy equals
