please help I'm am having lots of trouble undersanding electric circuits. my question says " use kirchhoff's loop rule and ohm's law to derive the equation for the equivalent resistance of four resistors connected in a series. concisely explain each step. " so i know that the eqaution for...

i have this question its worth 12 marks so I'm just wondering if i did it properly. the question is "the following diagram shows two charged objects, 1 and 2, and their positions relative to point p" object 1 ----------------object 2---------------p q1=+6.00microC q2=-3.00microC...

i need help on how to start to solve part c in a 3 part question. the question reads "Jerry is stationary on his skateboard at the top of the hill shown in the following diagram. he than rolls from rest down the hill. A) assuming that the hill provides a frictionless surface, determine jerry's...

two bullets of eqaul mass are shot at equal speeds at blocks of wood on a smooth ice rink. one bullet, made of rubber, bounces off the wood. the other bullet, made of aluminum, burrows into the wood. which bullet makes the wood move faster? why? i said the rubber bullet will make the wood...

i know that the formula for impulse is f(delta)t. my question ask " a truck with a mass of 1.20 x 10^3 kg has its brakes applied for 5.50s as it slows down from 24.0m/s, west to 10.4m/s west. determine the magnitude and direction of the impulse provided by the brakes." i know you need to use...

if you drop any kind of ball onto a hard surface, it will never bounce as high as the height it was dropped from. show algebraically that michanical energy has been lost between the maximum height on hte one bounce and the maximum height on the next bounce, and explain why this does not...

i'm not sure how to begin this problem. "a cart that is moving at 8:00m/s heads up a frictionless ramp inclined 10.0 degrees from the horizontal. how far up the ramp should it go?" also i want to know if I'm on the right track with this question "give an example of each of the following...
