When transmitting power with a constant capacity far from a single-phase power transmission line with rated resistance so that the power loss on the transmission line is reduced by 100 times, a generator must be used at the place of transmission. Transformer. ideal has a loop ratio between windings and primary

Modify the equation fδt=δ (mv) to find the force of friction.

An astronaut in space cannot use a scale or balance to weigh objects because there is no gravity. but she does have devices to measure distance and time accurately. she knows her own mass is 77.4 kg , but she is unsure of the mass of a large gas canister in the airless rocket. when this canister is approaching her at 3.50 m/s , she pushes against it, which slows it down to 1.30 m/s (but does not reverse it) and gives her a speed of 2.60 m/s . what is the mass of the canister?

How can you measure the amplitude of a longitudinal wave?
