According to ohm’s law, determine the calculated current for these values in table a. voltage = 5 v, resistance = 20 ω: a voltage = 20 v, resistance = 20 ω: a voltage = 50 v, resistance = 20 ω: a

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

The charge on a charged sphere is: a)concentrated at its centerb)distributed uniformly throughout its volumec)clustered on its centerd)distributed uniformly over its surface

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
