Answer:

C. Takes heat in, does work, and loses energy heat.

Explanation:

Heat engine is a system makes use of thermal energy (heat) to in order to do mechanical work.

This occurs by converting the heat into mechanical energy. This energy is then used to do work.

The key characteristic of a heat engine is that the substance with which work is done by, goes from a higher temperature to a lower temperature.

Hence, it loses heat as it does work.

If an airplane is moving at a constant speed of 500 miles per hour in a straight line is it accelerating?
Zinaida [17]

No. It’s moving at a constant speed (speed is not changing) in a straight line (same direction so velocity is not changing) so it is not accelerating. Acceleration only occurs if there’s a change in speed/velocity.

Two 100kg bumper cars are moving towards eachother in oppisite directions. Car A is moving at 8 m/s and Car B at -10 m/s when th
DerKrebs [107]

Answer:

-10 m/s

Explanation:

When two cars collide then the momentum of two cars will remains conserved

  • Mass of two cars = 100 kg
  • Speed of car A = 8 m/s
  • Speed of car B = - 10 m/s
  • After collision the speed of car B = +8 m/s

By momentum conservation equation

               m1v1i+m2v2i=m1v1f + m2v2f

               (100)(8)+(100)(-10)=(100v)+(100)(8)\\                            v=-10 m/s
