Question 1

Rearrange the following formulae to make the letter shown in the square brackets the subject.

(a) \( V = IR \) \( [R]\) (b) \( C = 2\pi r \) \( [r]\) (c) \( y = 3x - 2 \) \( [x]\)
(d) \( v = u + at \) \( [u]\) (e) \( x = 2ab - 7\) \( [b]\) (f) \( PV = nRT \) \( [T]\)
(g) \( v = u + at \) \( [t]\) (h) \( y = 5 - 3x \) \( [x]\) (i) \( t = 9 - 2pq \) \( [p]\)
(j) \( S = \frac{1}{2}n(a + d) \) \( [n]\) (k) \( n\lambda = 2dsin\theta \) \( [sin\theta]\) (l) \( v^2 = u^2 + 2as \) \( [s]\)
