Proper apparatus positioning
Proper apparatus positioning is the last step of driving an emergency response vehicle to an emergency incident. Discuss the considerations that a driver/operator must keep in mind when positioning an engine at a working fire incident when a rural water system will be used. As part of your …
Kepler’s law of planetary motion
There are hundreds of moons in our solar system, and they come in many shapes, sizes, and types. Does Kepler’s law of planetary motion apply to moons? Explain.Why were Kepler’s Laws so important? What paradigm shift took place due to his laws?If the same force acts on the Moon from the Earth -and- on the …

Question 1 (6 marks)a) Newton’s universal law of gravitation describes the force of gravity acting on two masses. Thecorrect equation is,Fg = Gm1m2r2.Using dimensional analysis, determine the dimensions and SI units for the gravitational constantG. Here, Fg is a force, m1 and m2 are masses and r is a distance. (2 marks)b) Someone then tells …
