Answer:
22.5 hp
Explanation:
The power delivered to an object is given by :
Where
F is force and v is velocity of the car.
For the same force, power is directly proportional to the velocity.
So,
So, the new power is 22.5 hp.
Explanation:
A manometer is a device that measures air pressure using a container with a "U"-shaped tube open at one or both ends. In a closed manometer, a sample of gas is introduced into one end, which is then capped. ... This pressure represents the positive or negative difference between the gas pressure and atmospheric pressure
Answer:
Good question. The answer is abilities. or gender
Explanation:
<span>Remember the definition of acceleration:
a = Δv / Δt, this is change in velocity per unit of time.
Note that a and v are in bold to mean that they are vectors.
1) a body traveling in a straight line and increasing in speed: RIGHT:
Acceleration is the change in velocity, either magnitude or direction or both. So, a body increasing in speed is accelerated.
2) a body traveling in a straight line and decreasing in speed: RIGTH
A decrease in speed is a change in velocity, so it means acceleration.
3) a body traveling in a straight line at constant speed: WRONG.
That body is not changing either direction or speed so its motion is not accelerated but uniform.
4) a body standing still : WRONG.
That body is not changind either direction or speed.
5) a body traveling at a constant speed and changing direction: RIGHT.
The change in direction means that the body is accelerated. The acceleration due to change in direction is named centripetal acceleration.
