Find the magnitude f of the force that the wooden block exerts on the nail, assuming that this force is independent of the depth of penetration of the nail into the wood. you may also assume that v0≫2gl−−−√, so that the change in the hammer's gravitational potential energy, as it drives the nail into the block, is insignificant.

How do we measure or think of speed in the united states?

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 3.00 ms . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?

Describe the three ray tracing steps used to identify an image for the given situation.
