LHS: because alnx = lnx^a, 2ln2x = ln(2x)² = ln4x²

Now, because ln and e are inverse functions, we take both sides to the power of e. Therefore:

e^{ln4x^2 ...}

So first we need to write down the proportionality relationship the question states. If we let n be the number of balls and r be the radius of the balls we can say n (proportional symbol) 1/r³....

As with any exam task, you should balance using your own ideas to engage critically with the text with, maintaining a strong focus on the requirements of the question. Before you start, ensure that you ha...

Newton's Third Law looks at what happens when two objects interact with each other. The definition of Newton's Third Law is, "When one body exerts a force on a second body, the second body simultaneo...
