Electrons flow very slowly through a circuit, yet it does not take a noticeably long time for a lamp to light up when you turn on a distant switch. How quickly a lamp lights up after an electrical switch is closed does not depend on the drift velocity of the conduction electrons, but depends on the speed at which the propagates through the circuit, which is about the speed of light.

An astronaut floating in space is trying to use her jetpack to get back to her space station, but she is being pulled away by a nearby planet, as shown in the image below. her jetpack provides a constant thrust of 310 n. if she angles her jetpack in such a way that it cancels out the vertical force due to the planet's gravity, what is her net horizontal force? thaud 487 o a. 54.8 n toward the space station o b. 212.9 n toward the space station o c. 185.2 n toward the space station o d 956 n toward the space station
