Suppose that the original resistor is replaced by a resistor of the same physical dimensions but made of a material that has half the density of charges to carry current, but each carrier has double the charge of those in the original resistor. Further suppose that the potential drop across the resistor is the same as for the original The current through the new resistor will be:. a. Twice as big as for the original resistor.
b. The same as for the original resistor.
c. Half as big as for the original resistor.
d. You can’t tell from the information given.
e. Some other multiple of the original current.

Aballoon is rising vertically upwards at a velocity of 10m/s. when it is at a height of 45m from the ground, a parachute bails out from it. after 3s he opens his parachute and decelerates ata a constant rate 5m/s.when. (a) what was the height of the parachutist above the ground when he opened his parachute? (b)how far is the parachutist from the balloon at t=3s? (c)with what velocity does the parachutist hit the ground? (d)after how long does the parachutist hit the ground after his exist from the balloon?
