Q. A block of mass 1 sits on an inclined plane. A force of magnitude 60.0 is pulling the block up the incline. The coefficient of kinetic friction between the plane and the block is 0.500. The inclined plane makes an angle 30.0 with the horizontal
1. What is the total work done on the block by the force of friction as the block moves a distance 10-m up the incline?
2. What is the total work done on the block by the applied force as the block moves a distance 10-m up the incline?
Sketch a principle ray diagram showing the formation of the image. compute the position, size, orientation (erect or inverted), and nature (real or virtual) of the image.
Note down that since each oscillator is attached to two "springs", and each "spring" is half the length of the interatomic bond, the effective interatomic spring stiffness for one of these oscillators is times estimated value given above.
Monochromatic light ( = 630 nm) strikes a pair of slits at normal incidence, forming a double-slit interference pattern on a screen located 1.20 m from the slits. It shows the interference pattern observed on the screen. What is the slit separatio..
A rocket is fired at a speed of 75.0 m/s from ground level, at an angle of 60.0 degrees above the horizontal. The rocket is fired toward the ground 11.0-m high wall, which is located 27.0 m away. By how much does the rocket clear the top of the wa..
An RL circuit consists of a switch, an emf source Eo, a 4 kΩ resistor, and a 5 H inductor. If the potential across resistor is 16 V 5 ms after switch is closed, find out the source emf, Eo.
A source emits sound uniformly in all directions. There are no reflections of the sound. At the distance r1 from the source the sound is 3.9 dB louder than it is at a distance r2 from the source. What is the ratio r1/r2.
Sketch and describe a floe control loop.
