Asinusoid al em wave of frequency 80 mhz travels in free space in the x- direction. (a) find the period and wavelength of the wave. (b) at some instant and location, the e field has its maximum value of 650 n/c and is directed along the y-axis. find the magnitude and direction of the magnetic field b at this position and time. (c) write an expression for b in unit vector notation using a cos function, with w. numericat values for bmax, k, and

Amanometer is used to measure the air pressure in a tank. the fluid used has a specific gravity of 1.25, and the differential height between the two arms of the manometer is 34 in. if the local atmospheric pressure is 12.7 psia, determine the absolute pressure in the tank for the cases of the

Aperson stands on a platform, initially at rest, that can rotate freely without friction. the moment of inertia of the person plus the platform is ip. the person holds a spinning bicycle wheel with its axis horizontal. the wheel has moment of inertia iw and angular velocity ωw. take the ωw direction counterclockwise when viewed from above. part a what will be the angular velocity ωp of the platform if the person moves the axis of the wheel so that it points vertically upward?
