Speed and direction are the two scientific componets that make up velocity.
Answer:
25 mi/hr
Explanation:
Distance = 200 miles
Time = 8 hours
Substitute values into the given equation and solve.
Answer:
the total kinetic and potential energy of its particles
Explanation:
In every object, there are two types of energy which can be found inside them-Kinetic and Potential Energy. For example, a solid object placed on a stationary table has a potential energy due to the vibration of the molecules of the object.
As the object is moved across the table, it has kinetic energy. The combination of both energy is known as thermal energy. An increase in both energy leads to increase in the thermal energy of a given object.
The correct answer is:
The volume of the gas decreases
Explanation:
As the piston is forced down work is done on the gas. The force exercised by the gas pressure on the piston is in the adverse direction of the motion of the piston. The volume of the space the gas absorbs decreases. When we let go of the piston the gas extends. The force exercised by the gas is in the similar direction as the motion of the piston and work is done by the system.
