hooke's law determine that if a small weight is suspended from a spring,the length of the stretched spring y, is a linear function of the weight, x. determine the linear equation if the unstretched spring is 12 inch and weight of 2 lbs stretches it to 16...

newton’s law of gravitation states that any two bodies attract each other with a force that is inversely proportional to the square of the distance between them. The force of attraction between two bodies is 460 * 10^-12 newtons when they are 6 cm apart....

e AM and FM radio waves are transverse waves consisting of electric and magnetic disturbances traveling at a speed of 3.00 x 10 8 m/s. A station broadcasts an AM radio wave whose frequency is 1230 x 10 3 Hz. (1230 kHz on the dial) and an FM radio wave who...

A block is pulled across the floor by a pull of 400 N at an angle of 35˚ with the horizontal. The force of the kinetic friction is 150 N, and the block is moved a horizontal distance of 23 m. What is the resultant work?

A 40-kg sled rests at the top of a 34˚ incline that is 500 m long. If the coefficient of friction is 0.2, what will be the speed at the bottom of the slope? The 40-kg mass includes the mass of the person on the sled.
