Celina should perform the following method to get pure water:
Boil the water in a pan, as the water boils it changes into gas (water vapours) these vapours should be cooled down through the process of condensation which changes gas into liquid form, Through this process germs would be killed due to high temperature and the salt will remain in the pan as salt has higher boiling point than water,
Entropy measures disorder and nothing else
So to solve for this problem, this is computed by the
following steps:
Vp / Vs ( = Np / Ns
Where:
Vp = Voltage Primary
Vs = Voltage Secondary
Np = Turn ratio Primary
Ns = Turn ratio Secondary.
So plugging in our values: <span>
110 / 4.9 = N</span>p / Ns<span>
N</span>p / Ns =22.44, so <span>the answer is 22 coils.</span>
Answer:
3 : 08 : 10.9
Explanation:
assuming a 12 hour clock
angular velocity of the hour hand is 2π/(3600(12)) rad/s
angular velocity of the minute hand is 2π/3600 rad/s
difference is 2π/3600 - 2π/(3600(12)) = 11(2π/(3600(12)) rad/s
45° = π/4 radians
This angle is covered in a time of
π/4 rad / 22π / (3600(12)) = 900(12) / 22 = 490.909090... s
or about 8 minutes 10.9 s
