Q. A 100-kg cannon at rest contains a 10-kg cannon ball. When fired, the cannon ball leaved the cannon with a speed of 450 m/s. What is the recoil speed of the cannon?
Q. Very short pulses of high-intensity laser beams are used to repair detached portions of the retina of the eye. The brief pulses of energy absorbed by the retina welds the detached portion back into place. In one such procedure, a laser beam has a wavelength of 815 , and delivers 221 , of power spread over a circular spot 536 , in diameter. The vitreous humor (the transparent fluid that fills most of the eye) has an index of refraction of 1.34. What is the maximum value of the electric field in the laser beam?
If a 4-engine jet accelerates down the runway at 5m/s2 and 3 of the jet engines fail, how much acceleration will the other one produce.
A person carries a long pole of mass 10kg and length 3.40 m at the angle of 60 degrees. Find the magnitude of the torque on the pole by reason of gravity.
A 4.70 kg mass causes a vertical spring to stretch 0.850 meters. The spring is after that stretch and extra 0.270 meters and release (as a stopwatch starts) causing the spring and mass to oscillate.
The frequency of a tuning fork is 358 Hz. Find the length of the shortest organ pipe which will give 6 beats/s with the fork. The velocity of sound in air is 339.1 m/s.
What is the decibel level required for human perception
A 200 km long high-voltage transmission line 2 cm in diameter carries a steady current of 1050 A. If the conductor is copper with a free charge density of 8.8 x10^28 electrons per cubic meter, how various years does it take one electron to travel ..
Find out the resulting values of the processional rate
A certain organ pipe, open at both ends, produces a fundamental frequency of 256 in air.If the pipe is filled with helium at the same temperature, what fundamental frequency will it generate ? Take the molar mass of air to be 28.8 and the molar ma..
