The relationship between pressure and volume during the process is pV = constant. Sketch the process on a p-V diagram and determine the work, in kJ.
Find the probability that the sum is exactly 4 twice, when rolling the two dice 7 times. Find the probability that the sum is 10 for the first time, happens on the 20th roll of the two dice
Find the magnitude of the magnetic flux through the floor of a house that measures 22m by 18 m. assume that the earth's magnetic field at the location of the house has a horizontal component of 2.6 x 10^-5 T pointing North and a downward vertical
At a certain location the Earth's magnetic field has a magnitude of 5.9 x 10^-5 T and points in a direction that is 72 degrees below the horizontal. Find the magnitude of the magnetic flux through the top of a desk at this location that measures 1
The sample space of equally likely outcomes for the experiment of rolling two fair dice is :
Diffraction studies of crystals depend on interferences between planes of electron density, whose spacing must be greater than the wavelength. Since the shortest bonds are about 0.1 nm, such planes are unlikely to be closer than 0.1 nm.
A single conducting loop of wire has an area of .2 x 10^-2 m^2 and a resistant of 110O. Perpendicular to the plan of the loop is a magnetic field of strength .48 T at what rate ( in T/s) must this field change if the induced current in the loop is
