A convex lens forms a real and inverted image twice the size of the object. The magnification produced by the lens is equal to:
The value of \(\sqrt{729}\)+ \(\sqrt{1681}\)+ \(\sqrt{576}\) − \(\sqrt{1849}\) is:
Given that 48: x :: x: 75, we can write this proportion as a fraction: \( \frac{48}{x} \) = \( \frac{x}{75} \) Cross-multiplying, we get: 48 * 75 = x * x 3600 = x² x = \(\sqrt{3600}\) x = 60 Since x > 0, x = 60
