You are an astronaut in the space shuttle pursuing a satellitein need of repair. You are in a circular orbit of the same radiusas the satellite (370 km above theEarth), but 20 km behind it.
(a) How long will it take to overtake the satellite if youreduce your orbital radius by 1.0 km?
hr
(b) By how much must you reduce your orbital radius to catch up in7.0 hours?
m
When light of wavelength 360 nm falls on a lithium surface, electrons having a maximum kinetic energy of 1.15 eV are emitted. determine the work function of lithium
Suppose you take a 2.0×10^2ohm resistor and a 0.40 H inductor and make a series circuit with a voltage source that has voltage amplitude 30 V and an angular frequency of 2.5×102 rad/s. What are the voltage amplitudes across the resistor and across ..
