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

What is the producer surplus after the subsidy

What is the efficient output level (the output that maximizes total surplus in this market)?

Consider the following statements about income elasticity 1. For inferior goods, income elasticity is negative 2. For necessity goods, income elasticity is between 0 and 1 3. When income elasticity for a good is greater than 1, the share of income spent on the good is higher with higher income Which of the above statements about income elasticity are true?

Suppose that instead of a price floor, there is a price ceiling equal to $6. Consumer surplus equals
