Q. A shopping bag is hanging straight down from your hand as you walked across a horizontal floor at a constant speed. Does the force that your hand exerts on the bag's handle do any work? Define. Does this force do any work while you are riding up an escalator at a constant velocity?
A motorboat heads due east at 11.00 m/s across a river that flows toward the south at a speed of 3.40 m/s. What is the resultant velocity relative to an observer on the shore? If the river is 1360m wide, how long does take the boat to cross.
The resistance of a copper wire of length L meter is 0.1 ohms. If the diameter of the wire is 0.045cm, find out its specific resistance.
A tank with vertical walls, 2m wide and 2m long and 2.5 m high, is filled with 4800 litres of water (density 1000 kg/m3) and 3200 litres of light oil (density 900 kg/m3). compute the magnitude and location of the resultant force on each of the ver..
Find the magnitude of the acceleration for an electron in a uniform electric field with a magnitude of 122 N/C.
A 110kg clock initially at rest on a horizontal floor requires a 607N horizontal force to set it in motion. After the clock is in motion, horizontal force of 525 N keeps it moving with a constant velocity.
A 246 kg wooden raft floats on a lake. When a 80kg man stands on the raft, it sinks 4cm deeper into the water. When he steps off, the raft vibrates for a while.
Estimate approximately the angular deflection of the muon's trajectory, given that the rest mass of muon is 100Mev and that the saturation magnetization in iron is equivalent to 1.6 x 10^23 electron moments per cm^3.
A 650 kg weather balloon is designed to lift a 4600 kg package. What volume should the balloon have after being inflated with helium 0 degrees Celsius and 1 atm pressure to lift the total load.
A 12 kg weather rocket generates a thrust of 250 N. The rocket, pointing upward, is clamped to the top of a vertical spring. The bottom of the spring, whose spring constant is 560 N/m, is anchored to the ground. What is the rocket's speed while the s..
Assume that light of wavelength 550 nm is being observed. Also suppose that diffraction effects, rather than atmospheric turbulence, limit the resolving power of the telescope. Find the greatest distance that these stars might be from the earth.
Once a traffic light turns green, a car speeds up from rest to 50 mi/h with constant acceleration 9 mi/h • s. In the adjoining bike lane, a cyclist speeds up from rest to 20mi/h with constant acceleration 13mi/h.
What is the magnitude of F if box is speeding of with a constant acceleration of 0.18 m/s2.
