A small water droplet of diameter D = 100 μm and temperature Tmp = 0°C falls on a nonwetting metal surface that is at temperature Ts = −15°C. Determine how long it will take for the droplet to freeze completely. The latent heat of fusion is hsf = 334 kJ/kg. Hint: consider what will be true of the water droplet temperature given its initial temperature.

sonar - device which is used to find the submit submarines, sankalp ship. sonar waves consists of a transmitter and detector which are installed in the observation centre on board of a ship. the ultrasonic waves are sent into the sea at high frequency about 1000 khz in all direction.

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
