Conversations with astronauts on the lunar surface were characterized by a kind of echo in which the earthbound person's voice was so loud in the astronaut's space helmet that it was picked up by the astronaut's microphone and transmitted back to Earth. It is reasonable to assume that the echo time equals the time necessary for the radio wave to travel from the Earth to the Moon and back (that is, neglecting any time delays in the electronic equipment). Calculate the distance from Earth to the Moon given that the echo time was 2.56 s and that radio waves travel at the speed of light (3.00×10 8 m/s) .
An electron is moving at a speed of 1.0 x10^4 m/s in a circular path of radius of 2.1cm inside a solenoid. The magnetic field of the solenoid is perpendicular to the plane of the electron's path. The solenoid has 25 turns per centimeter.
What is magnitude of the force that a concrete support exerts on the bridge at each end. The cloth exerts a friction force of 0.100 N on the mug and the cloth is pulled with a constant acceleration of 3.00 m/s.
Three capacitors are arranged. C1 has a capacitance of 5.0 pF, C2 has the capacitance of 10 pF, and C3 has the capacitance of 15 pF. Find the voltage drop across the entire arrangement if the voltage drop across C2 is 311 V.
