1. In connection with the circuit drawn below, the value of current flowing through 2 kQ resistor is 10-4A. 2. 5V 1 www 2. 3. 4. 5. 6. 7. An audio signal Vm = 20 sin 2(1500t) amplitude modulates a carrier Vc = 80 sin 2 (100,000t)( The value of percent modulation is A hydraulic press can lift 100kg when a mass 'm' is place on the smaller piston. It can lift_ kg when the diameter of the large piston in increases by 4 times and that of the smaller piston is decreased by 4 times keeping the same mass 'm' on the smaller piston. The coefficient of static friction between a wooden block of mass 0.5kg and a vertical rough wall is 0.2. The magnitude of horizontal force that should be applied on the block to keep it adhere to the wall be N. A resonance circuit having inductance and resistance 2 104 H and 6.282 respectively oscillates at 10 MHz frequency. The value of quality factor of this resonator is [ = 3.14] A ball with a speed of 9m/s collides with another identical ball at rest. After the collision the direction of each ball makes an angle 30 with the original direction. The ratio of velocities of the balls after collision is x : y, where x is An inclined plane in bent in such a way that the vertical cross-section is given by y = where y is in vertical and x in horizontal direction. If the upper surface of this curved plane is rough with coefficient of friction = 0.5, the maximum height in cm at with a stationary block with not skip downward is cm.
