PLEASE PLEASE HELP WILL MARK BRAINLIEST SHOW WORK In 3 seconds a car moving in a straight line increases its speed from 22.4 m/s to 29.1 m/s while a truck increases its speed from 0 mph to 6.7m/s in the same amount of time. What is the acceleration of the car in m/s?

If a balloon is taken outside on a very cold day, what will occur?

Two kilograms of air within a piston–cylinder assembly executes a carnot power cycle with maximum and minimum temperatures of 800 k and 300 k, respectively. the heat transfer to the air during the isothermal expansion is 60 kj. at the end of the isothermal expansion the volume is 0.4 m3. assume the ideal gas model for the air. determine the thermal efficiency, the volume at the beginning of the isothermal expansion, in m3, and the work during the adiabatic expansion, in kj.

The ability to make things happen is also called a. heat b. force c. matter d. energy
