A high voltage 4.0 x 105 v power transmission line delivers electrical energy from a generating station to a substation at a
rate of 1.5 x 109 w. What is the current in the lines?
a
6853 A
b 3750 A
C2377 A
d 4599 A

Aturntable a is built into a stage for use in a theatrical production. it is observed during a rehearsal that a trunk b starts to slide on the turntable 10 s after the turntable begins to rotate. knowing that the trunk undergoes a constant tangential acceleration of 0.31 m/s2, determine the coefficient of static friction between the trunk and the turntable.

A10 kg box initially at rest is pulled 18 meters across a horizontal, frictionless surface by a 40 n force. what is the block’s final velocity over the 18 meters?

What are the similarities & differences between a thermistor and a light dependent resistor in physics?
