An electric power station that operates at 15 kV and uses a 15:1 step-up ideal transformer is producing 320 MW (Mega-Watt) of power that is to be sent to a big city which is located 270 km away with only 2.0% loss. Each of the two wires are made of copper (resistivity = 1.68 × 10-8 Ω.m). What is the diameter of the wires?

Ablock of mass m slides on a horizontal frictionless table with an initial speed v0 . it then compresses a spring of force constant k and is brought to rest. the acceleration of gravity is 9.8 m/s2. how much is the spring compressed x from its natural length? 1) x = v0*sqrt(k/(mg)) 2) x=v0*sqrt(m/k) 3) x=v0*((mk)/g) 4) x=v0*sqrt(k/m) 5) x=v0*(m/kg) 6) x=v0*sqrt((mg)/k) 7) x=(v0)^2/(2g) 8) x=v0*(k/(mg)) 9) x=(v0)^2/(2m) 10) x=v0*((mg)/k)
