Abullet of mass m and speed v passes completely through a pendulum bob of mass m. the bullet emerges with a speed of v/2. the pendulum bob is suspended by a stiff rod of length l and negligible mass. use conservation of energy and momentum to find the minimum value of v such that the bob will barely swing through a complete vertical circle.

Select light for the type of wave, adjust the wavelength so that the light is red, and increase the amplitude of the light to the max. then, select the start button at the source location to begin producing the waves. light is a form of electromagnetic wave, containing oscillating electric and magnetic fields. the wave amplitude detector mentioned above shows how the electric field oscillates in time at the location of the probe. the amplitude of the wave at the location of the probe is equal to the maximum electric field measured. how does the amplitude of the wave depend on the distance from the source?

Amother used 150 watts of power to raise a 15 newton object in a time interval of 8.0 seconds. through what vertical distance was the object raised ?

If jason ii needs 15 kw of power at 300 volts to operate, what amperage of current must flow through the cable?
