A compass originally points North; at this location the horizontal component of the Earth's magnetic field has a magnitude of 2e-5 T. A bar magnet is aligned East-West, pointing at the center of the compass. When the center of the magnet is 0.29 m from the center of the compass, the compass deflects 70 degrees. What is the magnetic dipole moment of the bar magnet? = A·m2

Which is a substance that can be separated by physical means and is not the same throughout

Mackinzie walks 4 blocks west, then 2 blocks south, then 4 blocks east, and,finally, 1 block south. what is the magnitude of her total displacement duringthis walk (in blocks)?

Asquare isothermal chip is of width w=5 mm on a side and is mounted in a substrate such that its side and back surfaces are well insulated; the front surface is exposed to the flow of a coolant at tinf=15 °c. from reliability considerations, the chip temperature must not exceed t=85 °c. if the coolant is air and the corresponding convection coefficient is h=200 w/m2 x k, what is the maximum allowable "power" of the chip? if the coolant is a liquid for which h=3000 w/m2 x k, what is the maximum allowable power of the chip?
