Answer:
Explanation:
As we know that the pressure inside the liquid level is given as
here we have
h = 10.9 km
also we know that
now we have
Resistance can be calculated by Ohm's law
As per ohm's law we will have
here we will have
voltage = 220 volts
current = 10 A
So by the above formula we will have
So resistance of the bulb is 22 ohm.
When the object slides across the rough surface some of its potential energy will be lost to friction.
<h3>Conservation of mechanical energy</h3>
The law of conservation of mechanical energy states that the total mechanical energy of an isolated system is always constant.
M.A = P.E + K.E
When the object slides across the rough surface, some of the potential energy of the object will be converted into kinetic energy while the remaining potential energy will be converted into thermal energy due to frictional force of the rough surface.
P.E = K.E + thermal energy
