Answer:
Explanation:
We start converting to SI units,
A mile = 1609m
We know that the expression, which can relate linear acceleration and angular velocity is given by,
Where is the angular velocity
r=radius
linear acceleration,
Re-arrange for \omega,
Our acceleration is equal to the gravity force, so replacing,
Answer:
The average death rate for this type of event is closest to 350 people per event.
Explanation:
Between the years 2048 and 2057
Is 10 years. Since there is only one chance of event between these years, there is no point to consider it.
The total number of events = 2940 chances.
average death rate per event = total number of dead people divided by total number of events of occurrence.
1000000/2940 = 340.134
The average death rate for this type of event is therefore closest to 350 people per event
