Because less energy is being wasted. non-renewable resources will last longer.
the cost is kept lower. hope it helps :)
Well, in my own personal case, I can actually move the air in either
direction through both of those.
When I move the air inward from the outside, it's warmed and moistened.
When I move it outward from the inside, it's not.
Answer:
The ping pong ball is hollow.
Explanation:
Since a ping pong ball, unlike the golf ball, is only filled with air, it is less dense. Air is notably LESS dense than solids, which is what comprises the inside of a golf ball.
<span>Acceleration of a projectile is a constant due to gravity. At the highest point, velocity equals zero.
</span><span>If we neglect air resistance, the only force acting on the ball after it's released is gravity, which is a constant downward force. So, as the ball is travelling upward the velocity decreases since the force acts opposite to its direction of motion. The acceleration remains constant as the force and mass are constant.</span>
Hello! For this excersice let's applicate the formula:
Data:
d = Distance = 150 m
v = Velocity = ¿?
t = Time = 0,9 s
Now, let's replace according the formula:
The velocity is <u>166,67 meters per second.</u>
