NOTE: Check your formula sheet if you have one these are often there.
Ac =
= rω^2
We know r = 4.00m
but what is ω?
ω =
= 2π*f
f is our frequency. we want it in seconds so we can divide by 60.
300/60 = 5rev/s
Ac = rω^2 = (4)(5)^2 = 100m/s
(b) Linear speed or v is equal to v = ω = (5)(4) = 20m/s
340 / 20 = 17
The speed of sound is 17 times faster.
NOTE: finished physics so i might be rusty and use an equation wrong. Tell me if something doesnt make sense. Im still new to this myself.
Other assumptions associated with this question are as follows:
- One person can feed on 1 hen/day for a year
- 1 hen must east 25 grasshoppers /day
- the total mass of 1000 grasshoppers is 1kg
- 600 grasshoppers are needed to feed 1 human per day
Grasshoppers is represented as Gh.
The total amount needed to feed the hen per year is:
- If expressed in Kg, then it would be 9,125/1000 which is
- = 9.125Kg/annum.
So if the farmer chose to live on grasshoppers rather than on hens, the calculation is given as follows:
- (90 kg/1 hour) x (24 hours/1 day) x (1 person/ 600 Gh)
The amount of Grasshoppers required is given as follows;
If the farmer can gather 90 Gh in one hour then,
- The total amount of Gh per day is 90 x 24 = 2,160
- the total amount of Gh available in a year is 2160 x 365 = 788,400 Gh/Year
- If 600 grasshoppers are quired to feed the human per day, then we work backward
- The total amount of Gh available in a day is 788,400/365. This is equal to 2160 Gh
- The total amount of people this can feed is given as 2,160/600
- Which is equal to 3.6 persons.
Since humans or people cannot be divided into fractions like a measure of sugar or a measure of liquid, the answer is best left to the most approximate digit with it 4 Persons.

Answer:A B+ is a 3.3 and a B- is a 3.0. Some schools might weight it differently, though, so it's best to email one of your teachers.
