It means that the potential difference between the metal can and the little button on top of the battery is about 1.5 volts.
That's strictly the result of the chemicals in the battery, and has nothing to do with its size. If a battery as big as a house has the same chemistry inside that the AA has, the big one will also have 1.5 volts between its terminals. (But it'll run your flashlight much longer than the AA will, before it runs down.)
Use. Weight = (mass)x(accel of gravity).
It'll be somewhere around approx roughly about in the neighborhood of 9.706667m/sec^2 .
From the definition of the first Law of thermodynamics we know that heat flows from the hottest object to the coldest. What has a refrigerator inside is a refrigerant that is traveling through some heat exchangers, driven by pumps and that allows the exchange of heat between a 'Hot' tank and then transport it to a certain place, eject it and return to extract more heat. In this way the refrigerant removes heat from a hot region to a cold region and heat enters said hot region. Since the heat extracted is greater than that of the medium, the heat from the inside flows outward.
The correct answer is B.
D.N(Newton) this is the S.I unit for force
Answer: assuming that the billiard balls are of identical weight the impacted billiard ball will move forward at around 0.5m/s (not considering energy conservation). The ball impacting the 2nd one would stop because most of its Kinetic energy would have been transferred into the not moving ball.
Explanation: hope this helps!
