Question 5
Rearrange the following formulae to make the letter shown in the square brackets the subject.
| (a) | \( V = \pi r^2h\) | \( [h]\) | (b) | \( x = \frac {a + y}{2 - y}\) | \( [y]\) | (c) | \( E = mc^2\) | \( [m]\) |
| (d) | \( v = u + at\) | \( [a]\) | (e) | \( V = IR\) | \( [I]\) | (f) | \( n\lambda = 2dsin\theta\) | \( [d]\) |
| (g) | \( a = \frac {v - u}{t}\) | \( [t]\) | (h) | \( a(x + d) + \frac{x}{d} = 2(x + 5)\) | \( [x]\) | (i) | \( f = \frac {uv}{u + v}\) | \( [v]\) |
| (j) | \( y = \sqrt{a - 2x}\) | \( [x]\) | (k) | \( I = \frac {W}{h^2}\) | \( [h]\) | (l) | \( a(x + 5) - (x + 2) = b(x + c)\) | \( [x]\) |
