An electric power station that operates at 30 kv and uses a 20: 1 step-up ideal transformer is producing 330 mw (mega-watt) of power that is to be sent to a big city which is located 260 km away with only 2.5% loss. each of the two wires are made of copper (resistivity = 1.72×10^−8 ω.m). what is the diameter of the wires?

Light from a sodium lamp passes through a diffraction grating that has 1000 slits per millimeter. the interference pattern is viewed on a screen 1.000 m behind the grating. the first (m = 1) two bright yellow fringes that are visible are 0.7288 m and 0.7300 m from the central maximum. what are the wavelengths of these two fringes?

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:
