In MKS (SI units), mass is expressed in kilogram (Kg), length in meter (m) and time in second (s). What would be the units for the following? a. Speed = distance/time b. Momentum = mass * speed c. Kinetic energy = (1/2)*mass*speed2 d. Force = mass*acceleration e. Work = Force * distance
Question no 11 If you were to calculate the poynting vector for various points in and around a transformer, what would you expect the field pattern to look like? Assume that an alternating potential difference has been applied to the primary windings and that a resistive load is connected across the secondary windings.
