# mass & density watch

1. stuck on a physics question, help me please.

"two of the wires used on a violin are made of steel, the two wires (labeled A & G) are both 500mm long between the pegs and support. the 500mm length of wire labelled G has a mass of kg. The density of steel is kg .

1, show that the corss-sectional are of the wire G is ."

density

with some simple rearranging we can get

where volume of a string = length times cross section area (C)

so we get

which should give you the correct answer!

what is E?

what is E?
short hand or x10

so 500E-3 means 500 x 10^-3

eh. - not use to informal short hand,
ok, thanks.

... its the short hand used by calculators which arent that new =P

oh, i get you,
the EXP button? (underneath pi on my calc)

what calculator?
casio with no natural display?

SVPAM
fx-85WA?

new models are

fx-83ES.

oh and D-Day i was being lazy D:

dont judge me
10. i was simply pointing out the pitfalls associated with using shorthand notation out-of-place and assuming others know what you're saying.
