What happens during the main sequence stage of a star?

A skater increases her speed uniformly from 2.0 meters per second to 7.0 meters per second over a distance of 12 meters. the magnitude of her acceleration as she travels this 12 meters is

Why is the work output of a machine never equal to the work input?

The principal limitation of wind power is unpredictability. True or False

A charge is accelerated from rest through a potential difference V and then enters a uniform magnetic field oriented perpendicular to its path. The field deflects the particle into a circular arc of radius R = 5 cm.

How much would a 100kg man weigh on the surface of the sun where the acceleration is 274 m/s

How much current is in a circuit that includes a 9 - volt battery and a bulb with a resistance of 12 ohms?

Find the current Voltage VD and current ID in the following circuit assuming (a) ideal diode. (b) Constant voltage drop model with Von = 0.75V (c) using the exponential model (I_0=1*10^ (-14)). Verify your results through Multisim simulation
