Martin sets up an experiment to see how the mass of a ball affects the distance it can roll off a ramp what is the independent variable (A) distance traveled by ramp (B) height of ramp (C) mass of the ball (D) length of the ramp

What occurs during a combustion reaction

An object with initial temperature 130 ∘ f is submerged in large tank of water whose temperature is 50 ∘ f . find a formula for f ( t ) , the temperature of the object after t minutes, if the cooling constant is k = − 0.2 . remember newton's law of cooling (the rate of change of temperature with respect to time is equal to k times the difference between the temperature of the object and the surrounding temperature) ! : )

The amount of potential energy possessed by an elevated object is equal to
