Find CT, V1, V2, V3 & UT, when C1 = 1F, C2 = 2F, C3 = 3F & QT = 4C.
A body dropped from rest falls half its total path in the last second before it strikes ground. From what height was it dropped?
in a geology class you were asked to determine miniscule pieces of rocks are magnetic or not. the problem is you don't have available magnets in the laboratory but few copper wires and a power supply. how will you identify the magnetic property of rocks?
Student drops a ball from a building and it takes 3 seconds to reach the ground. What was its speed before hitting the ground?
A hammer head, with a mass of 10.0 kg, strikes a nail at a horizontal velocity of 12.2 m/s and comes to rest in a time interval of 0.004 s. Find the impulse imparted to the nail and the average force the hammer exerted on the nail?
Rich Gossage set a fastball record by hurling a 0.14 kg baseball at a speed of 46.3 m/s. What was the magnitude of the ball’s momentum as it left his hand? *
What is the mass of a bus moving at a velocity of 110 kph if it has to fully stop before an intersection if a 7000-N of force is applied on it in 15 seconds? *
A golf ball with a mass of 0.06 kg is subjected to an impulse that causes it to move with a velocity of 50 m/s. If the golf club and the ball are in contact for 5x10^-3 second, what average net force acts on the ball?
A rectangular surface with horizontal dimensions of 4.0 cm and 5.0 cm is found in a uniform magnetic field directed at a 40° angle above the horizontal. Calculate the magnitude of the magnetic field that will yield a flux equivalent to 6.17 ✕ 10 -4 Wb.
