Oh no, a one in twenty chance has happened! Whatever shall we do!

um, what?

Can I just point out to everyone that whichever way this argument goes, it doesn't make it justifiable to believe that Jesus rose from the dead?

So many people make that mistake. Even if you manage to convince yourself logically that there's a supreme being, there's still a million miles to go before Christianity.

I am enrolled in AP physics and I need help remembering the formulas. I can't remember how to write them out and I'm wondering if there is a way to make it so that I don't forget them.

A commercial quality colour laser photocopier now costs $18000. The life expectancy for this type of copier is 5 years. A firm recently bought one of these copiers and wants to set up a sinking fund to raise the replacement cost of the copier.

It is necessary to consider inflation.

Use the fact that the same model photocopier cost $12250 in August 2003. The firm uses the diminishing value method to depreciate their current equipment by 8.5% p.a. To meet this future debt, the firm plans to invest in an annuity that offers 10% p.a. based on quarterly contributions to the annuity.

Calculate the precise size of the quarterly contributions that will have to be made in order for the annuity to contain the required amount of money necessary for the purchase of a new colour photocopier in 5 years time. State any assumptions you have made.

>a proton and an electron can combine into a neutron
>does that mean a neutron has more mass than a proton?
>check wolfram alpha: (neutron mass) - (proton mass)
>result: 2.5x mass of electron
>my face
Can someone explain what's going on with the mass here?
