Answer:
Therefore, the revolutions that each tire makes is:
Explanation:
We can use the following equation:
(1)
The angular acceleration is:
and the initial angular velocity is:
Now, using equation (1) we can find the revolutions of the tire.
Therefore, the revolutions that each tire makes is:
I hope it helps you!
Answer:
m = 9795.9 kg
Explanation:
v = 35 m/s
KE = 6,000,000 J
Plug those values into the following equation:
6,000,000 J = (1/2)(35^2)m
---> m = 9795.9 kg
Answer:
I think they use it at night because they want to avoid involving themselves in road accident while crossing the street. When there are reflective strips on their clothes, drivers do notice them even at far ends of the street since the strips will reflect the rays from the car lights to the driver,hence, the driver notifies that there is a pedestrian crossing and therefore slows down.
V = f * wavelength
as we know electromagnetic wave has speed equal to light, so
3 * 10^8 = f * 1.3
f = 2.3 * 10^8 hertz
f = 230 mega hertz
Pressure increases with increasing depth. h2=2hh
