Janeth and silly Sally both leave their phones on their desks about 0.75 meters apart. If Silly Sally's phone weighs 0.15 kg and Janeth's phone
weighs 0.25 kg, calculate the gravitational force between the two phones.

Many machines- including inclined planes such as ramps- increase the strength of the force put into the machine but decrease the distance over which the force is applied.

Asun-sized star will spend most of its lifetime as a: white dwarf red giant protostar main-sequence star

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 equation 2: 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!
