Question
The colour of sky appears blue due to –
Solution
The sunlit sky is blue because air scatters short-wavelength light more than longer wavelengths. Since blue light is at the short wavelength end of the visible spectrum, it is more strongly scattered in the atmosphere than long wavelength red light. The result is that the human eye perceives blue when looking toward parts of the sky other than the sun.
324² × 36 ÷ 18⁵ × 1120 =?
If 28957.5 ÷ 268.125= 108, then 289.575 ÷ 2681.25 is equal to:
(96% of 1100) + 92 × 4 = ? + 46 × 16
28 × 3.5 +25 × 3.2 = ? - 62
25% of 140 + 2 × 8 = ? + 9 × 5
236.23 - 653.23 + 696.23 = ?
What value should come in place of (?) question mark in the given expression.
75% of 320 + 40% of 150 = ?
13 X ? = 85 X 4 + √81 + 2
Simplify: 0.125 + 0.375 + 0.5 and express the answer as a fraction in simplest form.
