Answer:
Option B is correct.
Explanation:
Potential energy or chemical potential energy is used to Cook food which is then converted into thermal energy. The type of energy used also depends upon the type of cooking appliances used.
For e.g. stove convert potential energy to thermal energy.
The impact speed will be
v^2 = 2*9.8*1.3
v^2 = 25.48
v= 5.04 m/s

Generally the equation for Volume flow rate is mathematically given by




Generally the equation for Friction factor is mathematically given by

Where Re
Re=Reynolds Number



Therefore



Generally the equation for Friction factor is mathematically given by



Where




Answer
given,
angular speed of the tub = 5 rev/s
time = 9 s
he tub slows to rest = 15.0 s
the angular acceleration



angular displacement




case 2
now,


time = 15 s
the angular acceleration



angular displacement




total revolution in 24 s
= 23 + 38
= 62 revolution
