India’s first indigenously designed and developed high thrust cryogenic rocket engine generating a nominal thrust of 19 tonnes was successfully endurance hot tested for a duration of 800 seconds on July 16, 2015 at ISRO Propulsion Complex, Mahendragiri.

The engine will be used for powering the Cryogenic stage (C25), the upper stage of the next generation GSLV Mark-III launch vehicle of ISRO, capable of launching four tonne class satellites.

This cryogenic engine of C25 Stage operates on Gas Generator Cycle using extremely low temperature propellants – Liquid Hydrogen (LH2) at 20 Kelvin (-253 deg C) and Liquid Oxygen (LOX) at 80K (-193 deg C).

The ultraviolet rays have high frequency and shorter wavelength are converted to visible white light with lower frequency and greater wave length

Railway Minister Suresh Prabhu on 18th March, 2017 flagged off the first fully India-made suburban train 'Medha'.

In each row, 

Sum of 1st two digit number + last two digit number = Middle two digit number

i.e., 1st row 15 + 40 = 55

2nd row 46 + 47 = 93

Similarly, 7x + 16 = 87 => x = 1.
