An alarm clock draws 0.5 A of a current when connected to a 120 volt circuit. Calculate its resistance
PLEASE HELP!!!!!! suppose that mA is 8.1 kg and mBis 6.5kg. The distance between their centers is 0.5o m.Calculate the force of attraction between these two bodies?
A classmate states that continental drift could not be possible because it would take far too much force to move tectonic plates. describe the hypotheses scientists use to explain the movement of tectonic plates. why hypothesis do many scientists think may explain the great force needed to move plates?
Calculate the Energy (E) in joules for that wavelength and record it in the table below. Remember that E = HF, where h the Planck constant (6.6 *10^-34 j*s)
during a test crash an airbag inflates to stop a dummies forward motion. the dummies mass is 75 kg. if the net force on the dummy is 825N toward the rear of the car what is the dummies deceleration
a block of mass M is initially at rest on a frictional less floor. the block, attached to a massless spring with spring constant k, is initially at its equilibrium position. an arrow with mass m and velocity v is shot into the block. the arrow sticks in the block. what is the maximum compression of the spring
