Homework Statement
So basically I have plotted two variables I measured on a graph, which gives a simple linear relationship, and have found the gradient and standard error of the gradient (1.21251 and 0.03275 respectively). Now my problem is that this gradient is equal to a constant divided...

A car, of mass 720kg, moves along a straight horizontal road. The engine of the car exerts a constant power of 81kW. The car experiences a resistance to motion which has magnitude 90v N, where v ms^-1 is the speed of the car at time t s
(a) Show that v satisfies the...
Well I assume it means the diameter of the planet as you see it from your position, such that the moon appears roughly half the size of the sun when viewed from Saturn relative to the size of the sun in the sky viewed from the earth, but then this is all depends on the distance you are from the...

Ah it's cool, I think I figured it out, I just didn't think about one thing.
And I didn't realize about the template, I will ensure I follow it next time!
