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) | \( v^2 = u^2 + 2as \) | \( [s]\) |
