Answer:
Vertical velocity decreases.
Explanation:
The motion of the ball is a projectile ball, which consists of two independent motions:
- a horizontal motion, with constant velocity
- a vertical motion, with constant acceleration g=9.8 m/s^2 towards the ground
In the vertical motion, there is a constant acceleration directed downward: this means that the vertical velocity decreases as the ball goes higher. In fact, it decreases following the equation
And it decreases until the ball reaches its maximum height, then it starts increasing again.
Combustion, also known as burning, is the basic chemical process of releasing energy from a fuel and air mixture. In an internal combustion engine (ICE), the ignition and combustion of the fuel occurs within the engine itself. The engine then partially converts the energy from the combustion to work.
Answer:
Explanation:
The human body utilizes the effect evaporation for cooling. Hence the water on the body surface make the skin to experience chilly as the wind blows to evaporate it. As the latent heat of vaporization is extracted from the body, it is cooler in the process. This is the same reason why perspiration cools the body as the sweat evaporate from the surface of the skin.
