I think I sort of understand, does it take all of the voltage in apart from a certain amount? so say you havea 4v zener, does it absorb all the volts but the 4? I've googled it but I really need to ask questions to understand.

1000?

Thank you!

So make the equation equal to one million and solve?

So c is 3000

the question says the bacteria will overrun the world if its population reaches one million. Its asking if the bacteria will reach that amount

Homework Statement dP/dt = (3000)/(1+0.25t) This gives the rate population changes at We also know P is 1000 when t is 0 (days) The Attempt at a Solution The anti derivative 12 000 x Ln(1 + 0.25t) + c Do I just make this equation equal to one million?

from the vertical. So I guess if I do two different tests, one with a person at 40kgs and one at 80kgs where the tension is the same can you find it the angle?

Ahh I think I get it, when you make the weight bigger the angle increases? But there would be a point when it doesn't increase any moreand starts to decrease. I think I understand that part now! You've been such a great help!

So we have tension and weight/gravity. Is the resulting force pushing the chair away from the centre of the spinning?

Don't we have three forces? Gravity, lift and tension? Possibly four with weight?

Yeah I guess it is, if we assume that the thing isn't stretchy is it always the same force? Then the weight of the object its another force?

We learned that the force is simply called lift. I don't know of that is the correct term or not. i've got it in front of me, at a stand still its those two forces but when you turn the chair o plane there is third force pushing it out, right?

There is force pushing the chair up from the ground and one pushing it down (I guess gravity). What next? :)

Conical pendulum question help!? Homework Statement By resolving forces horizontally and vertically and using Newtons second law, find an expression for the angle swung out. You must use calculus where needed. Use this analysis to answer questions 1-3 Q1: Will a child swing at a greater...
