Q1. Microwave signals are beamed between two mountaintops 51 apart. How long does it take a signal to travel from one mountaintop to other?
Q2. Solar cells convert the energy of incoming light to electric energy; a good quality cell operates at an efficiency of 15 percent. Each person in the United States uses energy (for lighting, heating, transportation, etc.) at an average rate of 11. Though sunlight varies with season and time of day, solar energy falls on United States at an average intensity of 200. Assuming you live in an average location, what total solar-cell area would you need to provide all of your energy needs with energy from the sun?
How many 185 W lightbulbs can you use in a 191 V circuit without tripping a 15 A circuit breaker? (The bulbs are connected in parallel, which means that the potential difference across each lightbulb is 131 V.)
At what angle must the cannon be fired
Find out the mutual inductance per unit length between two long solenoids, one inside the other, whose radii are r_1 and r_2 and whose turns per unit length are n_1 and n_2.
Two ocean liners, each with a mass of 40,000 metric tons, are moving on parallel courses, 92 m apart. What is the magnitude of the acceleration of one of the liners toward the other due to their mutual gravitational attraction? Care for the ships as ..
A motorist travelling at 17m/s encounters a deer in the road 49m ahead. If the maximum acceleration the vehicle's brakes are capable of is -7 m/s2. If his or her reaction time is 1.9987 s, how fast will (s) he be travelling when (s) he reaches dee..
In outer space, far from other objects, block 1 of mass 30 kg is at position m, and block 2 of mass 1350 kg is at position m. What is the (vector) gravitational force acting on block 2 because of block 1? It helps to make a sketch of the situatio..
At rest, the car's horn sounds at a frequency of 455 Hz. The horn is sounded while the car is moving down the street. A bicyclist moving in the same direction with one-third the car's speed hears a frequency of 427 Hz. What is speed of the car.

A crate of 31.9- tools rests on a horizontal floor. You exert a gradually increasing horizontal push on it and observe that the crate just begins to move while your force exceeds 345. After that you must reduce your push to 247 to keep it moving at a..
A ball of mass 1.020 g and positive charge q =45.2 microC is suspended on a string of negligible mass in a uniform electric field. We view that the ball hangs at an angle of theta=15.0 from the vertical. What is the magnitude of the electric field.
