We observe two charges separated by a distance of 1.00 meters. If the distance between the two charges is changed to be half what it was, by what factor would the electric force of between them be changed. That is, what is the ratio of the new for
A piece of aluminum (specific heat 0.910 kJ/kg 0C) of mass 175 g at 74 0 C is dropped into a Styrofoam cup filled with 183 ml water at 20 0 C.
A 7.4 g bullet leaves the muzzle of a rifle with a speed of 493.1 m/s. What constant force is exerted on the bullet while it is traveling down the 0.8 m length of the barrel of the rifle?
A bullet of mass 5.00 g is fired horizontally into a wooden block of mass 1.26 kg resting on a horizontal surface. The coefficient of kinetic friction between block and surface is 0.160. The bullet remains embedded in the block, which is observed
The line joining the two charges the potential is zero. (Assume the potential is zero very far from all charges.) What is the ration q/q'?
The rms electric field of an electromagnetic wave increases from 298 to 894 N/C. (a) Determine the wave intensities for the two values of the electric field.
A 0.450-kg ice puck, moving east with a speed of 3.00 mis, has a head-on collision with a 0.900-kg puck initially at rest. Assuming a perfectly elastic collision, what will be the speed and direction of each object after the collision?
Bats are capable of navigating using the earth's field-a plus for an animal that may fly great distances from its roost at night. what is the proper orientation of the coil?
A sledge loaded with bricks has a total mass of 19.0 kg and is pulled at constant speed by a rope. The rope is inclined at 20.3° above the horizontal, and the sledge moves a distance of 20.3 m on a horizontal surface. The coefficient of kineti
Consider a convergent lens with a focal length f. An object is placed at a distance p=3/2 f. to the left of the lens.now place a convergent lens with a same focal length at a distance d=f behind the first lens.
