Derive the formula for the kinetic energy of an object of mass m, moving with velocity v

What should the power status of a circuit be when measuring resistance with an ohmmeter?

An object with initial temperature 130 ∘ f is submerged in large tank of water whose temperature is 50 ∘ f . find a formula for f ( t ) , the temperature of the object after t minutes, if the cooling constant is k = − 0.2 . remember newton's law of cooling (the rate of change of temperature with respect to time is equal to k times the difference between the temperature of the object and the surrounding temperature) ! : )

Is there a point between a 10 nc charge and a 20 nc charge at which the electric field is zero?
