Consider the four free body diagrams. Free-body diagrams are used to show the magnitude and direction of all forces acting on an object in a given situation. Do any of the free body diagrams indicate motion? If yes, which one(s).

The slope of a velocity time graph over any interval of time gives the during that interval

The weights of bags filled by a machine are normally distributed with a standard deviation of 0.05 kilograms and a mean that can be set by the operator. at what level should the mean weight be set if it required that only 1% of the bags weigh less than 9.5 kilograms? round the answer to 2 decimal places.

Ascientist notices that an oil slick floating on water when viewed from above has many different colors reflecting off the surface, making it look rainbow-like (an effect known as iridescence). she aims a spectrometer at a particular spot and measures the wavelength to be 750 nm (in air). the index of refraction of water is 1.3
