How can I start and solve this?

Question

The resonant frequency of a circuit may be found by the formula fequals
StartFraction 1 Over 2 pi StartRoot LC EndRoot EndFraction
where f is in cycles per? second, L is in? henrys, and C is in farads. Find the resonant? frequency, to the nearest? thousand, of a circuit if Lequals
7.199 times 10 Superscript negative 4
henrys and Cequals
4.3 times 10 Superscript negative 11
farads.

Answer 1

Frequency f = 1 / (2pi * sqrt(LC))   Note: sqrt(x) is square root of x and pi is the pi value 3.14159.......

 

L = 7.199x10^-4

C = 4.3x10^-11

 

Assuming the rounding is to the nearest THOUSAND and not THOUSANDTH

 

Solution: just plug values of L and C above in the formula for the frequency and use a calculator to find the result to the nearest THOUSAND (nearest thousand means that for instance if f = 1535.1368935219 you round it 2000. You need to know the rounding rules though. If you rounded it to the nearest thousandth it would be f = 1535.137)
