make Use of Stefans law to calculate the total power. What is the magnitude and direction of the force she exerts on you.
The distance to the Andromeda Galaxy is estimated at about 2 ´ 106 light years. A light year is distance travelled by light in one year; if the speed of light is 3 ´ 108 m/s, about how far is it from our galaxy to Andromeda? (1 year = 3.15 ´ 107 s..
A 13.00 g bullet travelling 236 m/s penetrates a 2 kg block of wood and emerges cleanly at 179 m/s. If the block is stationary on a frictionless surface as hit, how fast does it move after the bullet emerges.
The current in a series circuit is 6.0 A. When an additional 17.0 resistor is inserted in series, What is the resistance in the original circuit
The Moon moves noticeably on the celestial sphere over the space of a single night. To show this, calculate how long it takes the Moon to move through an angle equal to its own angular diameter (0.5 degrees) against the background of the stars. Gi..
A submarine is 304 m horizontally out from the shore and 126 m beneath the surface of the water. A laser beam is sent from the sub so that it strikes the surface of the water at a point 232 m from the shore. If beam just strikes the top of a building..
