An apple breaks off from its branch and falls toward the ground 9 m below, accelerating all the way. At point S the apple is 6 m from the ground. At point T the apple is 3 m from the ground. How does the sum of the gravitational potential and kinetic energies of the apple compare between point S and point T?

In which situation has the independent variable for the experiment been changed? check all that apply. changed from counting the number of duckweed at day 0 and day 14 to counting them every day changed from testing duckweed growth in beakers to testing duckweed growth in large outdoor tanks changed from testing the effect of ph on duckweed growth to testing the effect of light levels on duckweed growth changed from testing the effect of acid ph on duckweed growth to testing the effect of basic ph on duckweed growth

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)

The first law of thermodynamics states that heat added to a system is neither created nor destroyed but is as it changes into other forms of energy.
