The electric potential of a charge distribution is given by the equation v(x) = 3x2y2 + yz3 - 2z3x, where x, y, z are measured in meters and v is measured in volts. calculate the magnitude of the electric field vector at the position (x, y,z) = (1.0, 1.0, 1.0)

Aheat engine that operates on a carnot cycle has an efficiency of 0.420 when its low-temperature reservoir is at 10 ∘c. part aby how many degrees celsius must you increase the temperature of the high-temperature reservoir to increase the efficiency to 0.600 if you continue to use the same low-temperature reservoir?
