An observer on Earth receives a signal of 6.614 THz. Thirty minutes later, he receives another signal, followed by a third signal 24.331 minutes later after the second. The observer on Earth knows that the ship should be sending signals at a 2.500THz. How far away is the ship from Earth and how often is the captain of the ship sending signals according to her watch? (Hint: look up the formula for the Relativistic Doppler Shift.)

A plane flies over the head of Paul, an Earth observer. Treat Earth and the plane as inertial frames. The plane’s speed is v. When the plane is directly overhead, a light signal is emitted from the center of the plane. It is subsequently detected by two observers, Jack in the front of the plane, and Ben in the back of the plane. They both measure the distance to the center of the plane to be d. a. Assume the...

Signal transduction refers to any process of changing one signal to signal of another type. An example would be a series of pulsing lights into the sound for the word: "Help". Discuss how this transduction could be done by a device.

A helicopter flying at a distance of 20.0 km from a radio transmitter receives a signal of intensity 35.1 μW/m2 . A) Find the magnitude of the electric component of the signal at the helicopter’s location. B) Find the magnitude of the magnetic component of the signal at the helicopter’s location. C) If the radio transmitter radiates its signal uniformly over a hemisphere, what is the transmitted power?

A rock is dropped from the top of a tall tower. Half a second later another rock, twice as massive as the first, is dropped. Ignoring air resistance, they strike the ground with the same kinetic energy they strike the ground more than half a second apart. the distance between the rocks increases while both are falling. the acceleration is greater for the more massive rock.

The most efficient way to send a spacecraft from the earth to another planet is by using a Hohmann transfer orbit (the figure (Figure 1)). If the orbits of the departure and destination planets are circular, the Hohmann transfer orbit is an elliptical orbit whose perihelion and aphelion are tangent to the orbits of the two planets. The rockets are fired briefly at the departure planet to put the spacecraft into the transfer orbit; the spacecraft then coasts until it...
