The speed of light with the rise in the temperature of the medium remains unaltered because speed of light doesn't depend on temperature. It does depend, however, on the refractive index of the substance it is travelling through. The speed of light in vacuum, commonly denoted c, is a universal physical constant important in many areas of physics.
1240.04 – 360.18 + 449.98 ÷ 15.06 = ?
31.98% of 224.99 = 24.98% of ? + 9.91% of 499.99
? = 28.04² ÷ (4.01⁵ + 9.89 × 20.20) + 84.56% of (198.76 × 30.03)
(13.13 × 32.98) + 20.15% of 649.99 = ? + 122.34
(29.98% of 9840) + ? + (19.899% of 8490) = 7560
? + 163.99 – 103.01 = 24.01 × 6.98
A can complete a piece of work in 15 days. B is 30% more efficient than A. If they work together, how many days will it take to complete the work?
? * 4.89 = (410.15 ÷ 13.97) % of 6190 - 1342.77
22.22 × 8.99 + 142.15 = ?
