Newton's law of universal gravitation states that two particles exert a pull on each other with
magnitude F, ([kg - m/s]) that is proportional to the product of their masses mi ([kg]) and m: ([kg])
and inversely proportional to the square of their separation d ([m]).
Write down an equation for Newton's law of universal gravitation and determine the Sl unit of all the
proportionality constants you used.

- You are part of a team in an engineering class that is working on a scale model of a new design for a life vest. You have been asked to find the mass of a piece of foam that will be used for flotation. Because the piece is too bulky to fit on your balance, you break it into two parts. You measure the mass of the first part as 128.3 0.3 g and the second part as 77.0 0.3 g. a. What are the maximum and minimum values for the total mass you might reasonably report? b. What is the best estimate for the total mass of the foam? Hint: Propagation of uncertainty is described in Appendix A.arrow_forwardOne cubic centimeter of water has a mass of 1.00 103 kg.
