Physics or electronics? Help!

Could anyone please help with some vague time constant calculations? I know that T=CxR.

The questions set, are: 470mf x 100k (squiggle like an "n")
220mf x 1m ( " )
680mf x 2m ( " )
I assume the m's for million? but I don't even understand what's required!!
Thank you to anyone who can help!

Before I go,you should use a keyboard like mine Ice.
It's getting on a bit, and it's had many a pounding on the old keys,but yet they're still going strong.
I liked English too.I remember the teacher saying to me that my spelling was highly commendable,and my oral english was brilliant.Strangely enough,when it came to my general exams,I did better for my Welsh than my English.
In some lessons all the pupils in my class had a turn in reading from a book.Every time it came to one of my school chums he was a bit slow and stuttered a bit,and some of the class used to pretend to fall asleep.I did feel sorry for him though.Of course,when it came to my turn,I was up and away and the class tried their best to keep up with me!!Heh,heh!!
Right,I definitely have to go now.
I'll read any further answers in your thread during the weekend,and maybe I might pop a question on to make things more interesting.
See you soon.Night,night!!

Awww....well I'm afraid if Chris'd been my maths teacher, he wouldnt've just despaired - he'd have given up completely! I was bl00dy hopeless - yet oddly alright at physics! The two often go hand in hand, but not in my case! I was a bit of a rebel at school (lot!), but it was incredibly strict there, so I think most of us preferred to play up a bit, Despite that, the standard of education was very high, and I'm grateful for it now. It also taught us to have plenty of confidence and although I only left with 5 exam passes, the grades were good. I used to spend a lot of time helping the less fortunate ones though, and still do that now. Night night hun. x
