An RC circuit consists of a resistor with resistance of R=100 kΩ , a battery with emf of 100 V , and two capacitors with capacitances of C1=20μF and C2=60μF. Initially the capacitors are uncharged, and then the switch is closed at t=0.

a. How much charge will be stored in eah capacitor after a long time has elapsed?
b. What will the total charge on both capacitors two time constants after the switch is closed?

A33.1 g copper object is launched from a 1.5 m 30° steel incline positioned on the floor by being pulled up a string attached to a 50.0 g mass suspended vertically over a pulley. the object is projected towards a glass table where it lands when it is at the point along its trajectory with the lowest speed. it comes to a halt when it clears the opposite edge of the table. it then falls and lands on 9 physics texts each 5 cm thick that are stacked on the floor on the opposite side of the table. assume that the table does not have a ledge and the rectangular object experiences 0.05 n of air resistance as it falls towards the books. how far and how long did the object travel and how fast does it hit the books. assume that at the moment the copper object leaves the incline, the massless string and ideal pulley break off

If the speed of a particle triples ,by what factor does its kinetic energy increase?

Will you chech and finish these for me, because i am stumped with them.
