A current given by I(t)=4t4, where I is in amps when t is in seconds, passes through a 2-Ω resistor. How much charge passes through the resistor between t=3 s and t=5 s?

Explanation:

The charge passed during the interval of time is found by the integration the current function:

statement #3 on andre"s list is false.

one "light year" is the distance that light travels, through vacuum, in one julian year.   that's 365.25 days, of 24 hours each.
