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.
The sky is blue because air molecules in the air scatter blue light from the sun more than they scatter red light.
The independent variable is psychotherapy while the dependent variable is the people.
<h3>The types of variables.</h3>
In an experiment, there are two (2) main types of variables and these include the following:
<h3>What is an independent variable?</h3>
An independent variable can be defined as the variable that is being manipulated by an experimenter or researcher. This ultimately implies that, it is typically considered to be the cause in an experiment and it stands alone because it cannot be changed by any variable being observed or measured.
<h3>What is a dependent variable?</h3>
A dependent variable can be defined as the variable which signifies the effect of an independent variable and it is dependent on other factors because it's the part of an experiment that's being observed or measured.
Based on the information provided about this experiment, we can infer and logically deduce that the independent variable is psychotherapy while the dependent variable is the people.

Assuming we don't know the speed capabilities of the tractor, the time it would take simply be the rate in miles per hour. It has a direct correlation between speed and time spent, so the miles the tractor needs to plow is unneeded.
True because people go to school to learn skills and such, which costs effort and time and money to actually learn them
