The voltage of this circuit is 21V. The overall current is 6A at the battery. The resistors all have the same resistance. A) what is the voltage at each
resistor? B) What is the current at each resistor? C) Calculate the
resistance at each resistor. (hint, calculate only once as they are all the
same). ​

Name three different units of energy used to measure heat and describe what type of situations each is usually used.

The motor m applies a time-varying force of f (200 t) n, where t is in seconds. box b with mass 200 kg starts from rest, and the coefficients of kinetic and static friction are 0.2 and us 0.3 the acceleration due to gravity is g 9.8 m/s2 b 300 a) find the time ' when the box starts to move. b) calculate the speed of the crate at 3 s c) calculate the power delivered by the motor at t 3 s

This is the substance(s) formed in a chemical reaction.
