A source delivers an AC voltage of the form change in v = 98.0 sin (80(pi)t), where change in v is in volts and t is in seconds, to a capacitor. The maximum current in the circuit is 0.500 A.
(a) Find the rms voltage of the source.
(b) Find the frequency of the source.
(c) Find the value of the capacitance.
Air is streaming horizontally past a small airplanes wings such that the speed is 50m/s over the top surface and 30 m/s past the bottom surface. the plane has a mass of 300 kg and a total wing area of 5 m^2(both wings).
A stationary radar operator determines that a ship is 11.00 km south of him. An hour later the same ship is 24.0 km southeast. If the ship moved at constant speed and always in the same direction, what was its velocity for the duration of this tim..
Formulate a response that addresses whether or not you agree more guidance is needed and why; what you support and do not support about the proposal and why; and illustrate what modification you would make to the guidelines.
When high-energy charged particles move through a transparent medium with a speed greater than the speed of light in that medium, Calculate the speed of the electrons in the water. The speed of light in water is 2.25 108 m/s
