My Mum is looking after my Nan's key lime plant while she's away in Cyprus until early February. No offence to my Mum, but usually when she's looking after plants, they don't stay healthy for long.

And surprise, surprise, recently it has started getting numerous holes in the leaves, my Nan told my Mum that a few weeks ago she found a caterpillar in the pot. But won't all these holes make the plant die? And can anyone say what the holes might be caused, they're medium size? Can anything be done to help the poor plant get better? Please help!

And also, can anyone give me some advice so we can care for the plant without it dying? We're watering it enough [I think] by putting some water in the little dish below it so it doesn't drown. Advice please?

She's only been gone since Wednesday and I know my she will be distraught if it dies.

Help!
Thanks,
Lorna

The energy W stored in a flywheel is given by

W = kr^5N^2 (^) = the power of.

Where k is a constant
R is the radius
N is the number of revs

Determine the approximate percentage change in W when r is increased by 1.3% & N is decreased by 2%.

The answer states in the book 2.5% increase.
