The main scale of a vernier callipers has n divisions/cm. n divisions of the vernier scale coincide with (n – 1) divisions of main scale.
(D) \(\frac{1}{n^2}\) 1 V.S.D. = \(\frac{(n-1)}{n}\) M.S.D. LC. = 1 M.S.D. – 1 V.S.D. = 1 M.S.D. – \(\frac{(n-1)}{n}\) M.S.D. = \(\frac{1}{n}\) M.S.D. = \(\frac{1}{n}\times\frac{1}{n}\) cm ∴ L.C. = \(\frac{1}{n^2}\) cm

Convert the following degree Fahrenheit temperature to degree Celsius. i. 50 °F ii. 10 °F
Given : Temperature in degree Fahrenheit = 50°F To find : Temperature in degree Celsius Formula : °F = \(\frac{9}{5}\)(°C) + 32 Calculation : Substituting 50°F in the formula, °F = \(\frac{9}{5}\)(°C) + 32 50 = \(\frac{9}{5}\)(°C) + 32 °C = \(\frac{(50-32)\times 5}{9}\) = 10°C ii. Given : Temperature in...

Calculate the temperature which has the same value on fahrenheit scale and kelvin scale.
Given: TK = TF = x To find: Temperature at which Kelvin and Fahrenheit scales coincide (x) Formula: \(\frac{T_F-32}{180}=\frac{T_K-273.15}{100}\) Calculation: From formula. ∴ \(\frac{x-32}{180}=\frac{x-273.15}{100}\) ∴ 5(x – 32) = 9(x – 273.15) ∴ 5x – 160 = 9x – 2458.35 ∴ 4x...
