Calculate the speed of a proton after it accelerates from rest through a potential difference of 160 .
Dan is gliding on his skateboard at 4. He suddenly jumps backward off the skateboard, kicking skateboard forward at 8.00 (as measured by an observer on the ground). Dan's mass is 60 and skateboard's mass is 5.00 .How fast is Dan going as his fee..
A bead slides without friction around a loop- the-loop. The bead is released from a height of 24.7 m from the bottom of the loop-the- loop which has a radius 9 m.
What is the gauge pressure of the water at the pump? Suppose steady, laminar flow of water, no viscosity, and no air drag on the water jet. The acceleration of gravity is 9.81 m/s2.
A car drives straight off the edge of a cliff that is 64-m high. The police at the scene of the accident note that the point of impact is 110-m from the base of the cliff. How fast was the car travelling while it went over the cliff.
A cube of ice is taken from the freezer at -8.0 and placed in a 113 aluminium calorimeter filled with 306 of water at room temperature of 20.0. The final situation is observed to be all water at 15.0.
Compare the gravitational lens to the one found in a telescope.
After a tornado, a 0.60g straw was found embedded 3cm into the trunk of a tree. If the average force exerted on the straw by the tree was 90N, what was the speed of the straw when it hit the tree.
Discuss how big is a physical protocol data unit and determine the number of simultaneous transmissions for many network architectures.
An elastic cord is 64 cm long when a weight of 56 N hangs from it and is 69 cm long when a weight of 83 N hangs from it. What is the "spring" constant of this elastic cord.
Students hypothesized that by running the electric current through the wire of the apparatus shown here, they could cause the non-magnetic nail to exhibit magnetic properties. What would be a reasonable way to test this.
parachutist with a camera, both descending at a speed of 13 m/s, releases that camera at an altitude of 110-m.
A 8 kg box slides d = 4.2m down the frictionless ramp, after that collides with a spring whose spring constant is 250 N/m. angle is 30 degrees.
