An atomic bond can be modeled as atoms connected by tiny springs. For an atom tied to a spring the waves, where the positions x is the displacement from the equilibrium position. If the graph of the waves has an x axis of position x, and the y axis of amplitude, how would you be able to differentiate between the bond energies based on the waves in the graph?

A 676kW power station delivers power to a factory, How much less power is wasted in the transmission wires if the electricity is delivered from the power station at 54200V rather than 13700V
A 110kg crate, starting from rest, is pulled across a floor with a constant horizontal force of 350N. For the first 15.00 m the floor is frictionless and for next 15 m the coefficient of friction is 0.30. What is the final speed of the crate.
Consider a spacecraft in an elliptical orbit around the earth. At the low point, or perigee, of its orbit, it is 300km above the earth's surface; at the high point, or apogee, it is 2500km above the earth's surface. What if the rockets were fired ..
