On 2 A plane a runway
takes 19.6 seconds over a
distance of 1158 meter to take off from zero intial speed.
Assuming constant acceleration during take off.
b) What
is the acceleration (in ms ) during takeoff?

In a heat engine if 1000 j of heat enters the system and the piston does 500j of work, what is the final internal energy of the system if the inital energy was 2000 j1.write the equation2.list out your known variables 3. plug the numbers into the equations4.solve 5.write your solution statement that includes initial energy and final energy added.

Definition: this is the weighted average of all of the isotopes of an element.

This battery has a difference in potential energy between the positive terminal and negative terminal which units express this difference in energy
