No energy is lost in an ideal transformer, so the output power pout from the secondary coil equals the input power pin to the primary coil. suppose a neighborhood transformer delivers 300 a at 120 v. what is the current in the 1.4×104 v line from the substation?

Avalue that describes how heavy an object is and is related to the force of gravity is

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p

Achild has maximum walking speed of 1.6 m/s. what is the length of the child's legs? 0.26 m
