Hello sir please determine the power distribution in carrier and sidebands if the transmitted power is 1,000 W and mf = 1.
A 130 block on a frictionless table is firmly attached to one end of a spring with = 40. The other end of the spring is anchored to the wall. A 21 ball is thrown horizontally toward the block with a speed of 6.6.
Find out an effective coefficient of kinetic friction
Horse races once around a circular track in a time of 176 s, with a speed of 26 m/s. What is the radius of the track.
A professor's office door is 0.94 wide, 2.2 high, 4.0 thick; has the mass of 23, and pivots on frictionless hinges. A "door closer" is attached to door and top of the door frame. When the door is open and at rest, the door closer exerts a torque of 5..
