Please help me transpose these formulas.

Please show workings.


PLEASE SEE POST BELOW

Thanks

v = u + at

at = v -u

a = (v -u)/t


2. a^2 = b^2 = c^2

I don't know what you mean, perhaps

b^2 = a^2 = c^2

3. C = (n-N)/2pi

n -N = 2C pi

n = N - 2 C pi

3. V = pi r^2 /h

pi r^2 = hV

r^2= hV/pi

r = sqrt (hV/pi)

T = 2 pi/L/g

= 2pi g/L

2pi g = LT

g = LT/2pi



5. a = b +... NOT CLEAR - Check question

Thanks a lot terryg752.

I have posted a much clearer set of questions on my second post.

Its on the link.

Thanks.

1. T = 2 pi sqrt (L/g)

T/2pi = sqrt (L/g)

sqrt (L/g) = T/2pi

L/g = T^2/4pi^2

g/L = 4pi^2/T^2

g = 4L pi^2/T^2

2. a = b + sqrt(b^2 + c^2)

sqrt(b^2 + c^2) = a - b

b^2 + c^2 = (a - b)^2

b^2 + c^2 = a^2 -2ab + b^2

c^2 = a^2 - 2ab

c = sqrt (a^2 - 2ab)

OR c = - sqrt (a^2 - 2ab)

(2 values of c)
