An astronaut is traveling in a space vehicle that has a speed of 0.510c relative to Earth. The astronaut measures his pulse rate at 76.0 per minute. Signals generated by the astronaut's pulse are radioed to Earth when the vehicle is moving perpendicularly to a line that connects the vehicle with an Earth observer.
Find what pulse rate does the Earth observer measure? min-1
Find what would be the pulse rate if the speed of the space vehicle were increased to 0.950c?
min-1
a point charge causes an electric flux of -570 nmiddotm2c to pass through a spherical gaussian surface of 24.0 cm
A charge of -8.8 µC is traveling at a speed of 7.3*106 m/s in a region of space where thereis a magnetic field. The angle between the velocity of the chargeand the field is 52°. A force ofmagnitude 5.2*10-3 N acts on the charge. What is the magnitu..
The electric field between the plates of a paper-separated (K-375) capacitor is 8.20×10^4 V/m. estimate the area of each plate
It takes a minimum distance of 48.96 m to stop a car moving at 12.0 m/s by applying the brakes (without locking the wheels). Assume that the same frictional forces apply and find the minimum stopping distance when the car is moving at 26.0 m/s.
At rest, a car's horn sounds at a frequency of 480 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 470 Hz. What is the speed of the car?
