The Bugatti Veyron requires 2.40 s to accelerate from 0 to 60.0 mi/h. Calculate the distance that the car would travel in the ti
me it takes to reach 90.0 km/h, which is the speed limit on many Canadian roads. Compare your answer to the distance that the Saleen S7 Twin Turbo would travel while accelerating to the same final speed (The Saleen S7 Twin Turbo requires 2.8 s to accelerate from 0 to 60.0 mi/h).

Answer:
2.83m
Explanation:
The information that we have is
Intensity at 2.0 m: and
we need an intensity level of:
thus, we are looking for the distance .
which we can find with the law for intensity and distance:
we solve for :
and we substitute the known values:
at a distance of 2.83m the intensity level is 40dB
Answer:
Explanation:
The average angular speed of the Earth about the Sun is given by:
where
rad is the total angle corresponding to one revolution of the Earth around the Sun
T is the orbital period of the Earth
The orbital period of the Earth is 365.25 d. We must convert it into seconds first:
And by substituting into the equation above, we find the average angular speed:
