An rc circuit contains a resistor (r ohms), a capacitor (c farads), a switch k, a source of emf e. assume that the switch k is closed at time t 0, r-10, c- 0.02, q(0) 0, and e(t)-100e (volts). (a) graph the circuit diagram. (b) set up a differential equation for the current. (c) find q(t) and i(t). s.

Identical marbles are released from the same height on each of the following four frictionless ramps . compare the speed of the marbles at the end of each ramp. explain your reasoning

Which type of wave can travel without a medium

It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.2 gpa). as one goes deeper and deeper in the ocean, the pressure increases by 10000 pa for every meter below the surface. if a diver goes down 80.0 m in the ocean, by how much does each cubic centimeter of her blood change in volume? give the answer in cubic centimeters (actually one cubic centimeter equals one milliliter).
