A100-g bullet is fired from a rifle having a barrel 0.600 m long. choose the origin to be at the location where the bullet begins to move. then the force (in newtons) exerted by the expanding gas on the bullet is 15 000 1 10 000x 2 25 000x 2 , where x is in meters. (a) determine the work done by the gas on the bullet as the bullet travels the length of the barrel. (b) what if? if the barrel is 1.00 m long, how much work is done, and (c) how does this value compare with the work calculated in part (a)?

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
