When cooking food in a microwave, why is it more important to rely on the internal temperature of the food rather than on a previous cooking time?

The metric unit of electrical power is the watt volt ampere ohm

The 10-kg double wheel with radius of gyration of 125mm about o is connected to the spring of stiffness k = 600 n/m by a cord which is wrapped securely around the inner hub. if the wheel is released from rest on the incline with the spring stretched 225 mm, calculate the maximum velocity v of its center o during the ensuing motion. the wheel rolls without slipping

The speed of light can be used to measure the
