Consider two particles with position vectors 7, and 12. the force exerted by particle 2 on particle 1 is (6,72) = (2 - ) (r2 — rų). the force is (a) central and conservative (b) non-central and conservative (c) central and non-conservative (d) non-central and non-conservative

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

Within a pendulum, as potential energy decreases, energy increases. a. heat b. kinetic c. frictional d. gravitational

10 points! will mark brainiest! in a heat engine if 1,000 j of heat enters the system and the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2,000 j 1: write the equation2: list out your known variables 3: plug the numbers into the equations 4: solve 5: write your solution statement that includes initial energy and final energy added you so much!
