PLEASE HELP ME WITH THIS ONE QUESTION One 10 Ohm resistor, R1, is connected to a 12 V battery. A second 10 Ohm resistor, R2, is added in series. What is the potential difference across each resistor?

A) R1 = 12 V and R2 = 0V

B) R1 = 6 V and R2 = 6V

C) R1 = 10 V and R2 = 2 V

D) R1 = 0 V and R2 = 12 V

A23 kg log of wood begins from rest, 300 m up a sluice (a water track used to transport logs, think of it as an inclined plane with negligible friction) inclined at 20° to the horizontal. after it reaches the flat waterway at the bottom it collides elastically with a 100 kg block of wood initially at rest near the base of the incline. (a) how long does it take the 23 kg log to travel down the incline? (b) what is the speed of the 23 kg log at the bottom of the incline? (c) what are the velocities of both blocks of wood after the collision? (d) what is the total kinetic energy before the collision? (e) what is the kinetic energy of the 23 kg log after the collision? (f) what is the kinetic energy of the 100 kg block of wood after the collision? (g) what is the total kinetic energy after the collision? (h) compare the total initial and total final kinetic energies. is this consistent with what you would expect for elastic collisions? explain!

The combining of light nuclei is called blank. blank as in not actually blank. you know what im tryin to say.
