Which one of the following statements is incorrect? a)The elastic potential energy of an object is a measure of the object's ability to do work by virtue of its condition.
b) The gravitational potential energy of an object is a measure of the object's
ability to do work by virtue of its position.
c)
The kinetic energy of an object is a measure of the object's ability to do work
by virtue of its motion.
d)
Power is calculated as a ratio of the time taken divided by the work done on
an object.

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?
