Afloodlight at ground level is illuminating a building that is 100m away. a man 1.8m tall is walking from the floodlight to the building along a path that is perpendicular to the building. if he is walking at the rate of 1m/s, at what rate is his shadow on the building decreasing when he is 60 m from the building expert answer

State the following: boyle's law and charle's law

Suppose that a mass of 2 kg is attached a spring whose spring constant is 50. the system is damped such that b = 12 . the mass is set in motion with an initial velocity of -8 m/s at a position 0 meters from equilibrium. set up and solve a differential equation that models this motion. write your solution in the form a cos ( ω t − α ) where α is a positive number. use your solution to fill in the information below: what is the amplitude of the motion? what is the value of ω ? what is the phase shift?

Which is a substance that can be separated by physical means and is not the same throughout
