Use the exact values you enter to make later calculations. You measure the potential difference across a capacitor at different times while it's charging and record the following results. Voltage (V) Time (s)1.4790 0.015843.0000 0.036894.5210 0.066516.0210 0.11700

The final voltage the capacitor reaches after you go get some coffee is 6.500 V.
(a) Determine the time constant from the slope.

What is relative velocity? in which condition is relative velocity known by adding the velocity of the first body and that of the second body

Consider a system to be two train cars traveling toward each other. what is the total momentum of the system before the train cars collide?   kg • what must the total momentum of the system be after the train cars collide?   kg •  

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?
