pulling my hair out with this equation

[fatherjack]

33 ms = 33 x 10^-3 s = 0.033 s
So, the duty cycle is (0.033 s ÷ T s) x 100% = 3%


(what is the value of T)

Transposing the formula gives T s = insert your workings here =


= Ans A s
= Ans B ms
1 hour = 60min x 60 s = 3 600 s


So, in 1 hour the node transmits,
3 600 s = Ans C times
Ans A s


Therefore, node transmits for

0.033 s x Ans C =

= Solution (3 s.f.) in every hour

You showed your - but you did not tell us what the question was!!

= Solution (3 s.f.) in every hour

(0.033 s ÷ T s) x 100% = 3%

Transposing that equation gives T s = (100%/3%) (0.033 s)

Another way to say is is that 0.03 × T s = 0.033 s

Does that clarify the question? You should be able to find T s from either of those two statements. The next two questions convert s to ms and to hour.

Is what ..

33 ms = 33 x 10^-3 s = 0.033 s
So, the duty cycle is (0.033 s ÷ T s) x 100% = 3%


(what is the value of T)

= Ans A s
= Ans B ms
1 hour = 60min x 60 s = 3 600 s


So, in 1 hour the node transmits,
3 600 s = Ans C times
Ans A s


Therefore, node transmits for

0.033 s x Ans C =

= Solution (3 s.f.) in every hour[/QUOTE

What you seem to be saying is that your device is on 3% of the cycle period and that equals 33ms, and then asking how big the whole pie is (length of the cycle period) ... so to speak.

3 is to 100 as 33ms is to x, i.e 3/100 = 33ms/x ms. I think that is what you are asking.

Seconds are a 1000 times larger than milliseconds so just as you need to divide a number of pennies by 100 to get dollars, so to you need to divide the number of milliseconds by 1000 to get seconds.
