Answer:
Energy is an essential part of life because all of human activities require energy.
Answer:
v₂ = 48 mph
Explanation:
We know that,
Speed = distance/time
A German Shepherd takes 4 hours to cover a distance, if it travels at a speed of 36mph.
We need to find the speed to cover the same distance in 3 hours.
So, the new speed is 48 mph.
First, use a high-quality measurement tool. Next, measure carefully. Finally, repeat the measurement a few times. Hope it helps!
Answer:
Explanation:
The artificial gravity generated by the rotating space station is the same centripetal acceleration due to the rotational motion of the station, which is given by:
Here, r is the radius and v is the tangential speed, which is given by:
Here is the angular velocity, we replace (2) in (1):
Recall that .
Solving for :
