A flash of lighting is seen due north 4.0 s before the sound of the thunder is heard. If the air temperature is 27 C, find how much longer the sound of the thunder would take to reach the listener if the wind were blowing from the south at 48 km/h.
Draw a motion diagram for the train. Assume that the train is moving toward the right and starts to slow down at t = 0. The separation of each dot represents an elapsed time of one second.
Use the ideal gas as a model to estimate the rms speed of a free electron in a metal at the 273 K temperatures
Natural light is randomly polarized, which means that, on average, half the light energy is polarized along any given direction.
the magnetic coils of a tokamak fusion reactor are in the shape of a toroid having an inner radius of 0.700 m and an
The Vespertilionidae family of bats detects the distance to anobject by timing how long it takes for an emitted signal to reflect off the object and return. Typically the bats emit sound pulses 3ms long and 70 ms apart while cruising.
Consider two equal and opposite torques acting on a rotating object. The angular momentum of the object is:
In a series L-R-C circuit, the components have the following values: = 21.5 , = 165 , and = 400 . The generator has an rms voltage of 120 and a frequency of 1.25 .Determine the average power supplied by the generator. Determine the average power diss..

a cube of ice is taken from the freezer at -8.5 and placed in a 92 aluminum calorimeter filled with 314of water at room
On planet Tehar, the acceleration of gravity is the same as that onEarth but there is also a strong downward electric field with thefield being uniform close to the planet's surface.
A volleyball is spiked so that incoming velocity is 3.7m/s is changed to an outgoing velocity of -16 m/s.The mass of the vball is 0.34kg. what impulse does the player apply to the ball?
