What will be the primary voltage of a transformer if the secondary voltage is 60 V and there are 40 loops on the primary coil and 120 loops on the secondary coil?

Free runners jump long distances and land on the ground or a wall. how do they apply newton’s second law to lessen the force of impact?

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)

In a good thermo flask the main cause of heat loss is
