Attempt 3
you are designing the section of a roller coaster ride shown in the figure. previous sections of the ride give the train a speed
of 13.7 m/s at the top of the incline, which is h = 35.5 m above the ground. as any good engineer would, you begin your
design with safety in mind. your local government's safety regulations state that the riders' centripetal acceleration should
be no more than n = 1.93 g at the top of the hump and no more than n = 5.37 g at the bottom of the loop. for this initial
phase of your design, you decide to ignore the effects of friction and air resistance.
what is the minimum radius you can use for the semi-
circular hump?

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain

The release of energy by the nucleus of atom as a result of nuclear fission is radiant energy true false

[05.02] what is the best explanation of the kinetic molecular theory as it relates to the energy of the molecules in the states of matter? (1 point) the molecules in a gas have greater kinetic energy than those in a liquid, which in turn have greater kinetic energy than the molecules in a solid. kinetic energy cannot be created nor destroyed, and, as a result, all states of matter have the same kinetic energy. the molecules in a gas have greater kinetic energy; therefore, they are more tightly packed than the molecules in either a liquid or a solid. the molecules in gases and liquids, in constant motion, have greater kinetic energy than those in a solid, which do not move or vibrate because their position is fixed.
