Answer:
weight = mg
= 2 X 9.8 (g = 9.8m/s^2)
= 19.6 N is the correct answer
False
Explanation:
This is false because there is no solution and salt bridge to facilitate the movement of electrons from the two metals.
This connection is not an electrochemical cell because other components are absent. To fully form the electochemical cell which allows a potential difference to be set up;
- Presence of electrodes
- Presence of a solution
- Wire
- Salt bridge
Just wires and the electrodes are given in this set up and it will not work.

Answer:
D. Its temperature will remain 100 C until all the vapours condenses
Explanation:
Heat absorbed by a substance to change the state of matter is known as latent heat. This heat is utilized to break the bonds between atoms of the substance so that they can undergo phase change.
So, when water boils at 100 degree Celsius then temperature will remain constant unless and until all the water changes into vapor. As it is the latent heat that breaks the bonds between hydrogen and oxygen atoms of water so that liquid state can change into gaseous state.
Since latent heat is a hidden heat, that is why, it does not get reflected and there is no change in temperature due to it.
Thus, we can conclude that it is true that temperature will remain at 100°C until all the vapor condenses for a sample of water vapor at 101°C as it cools.
Answer: a) if a proton transforms to a neutron, a positron is produced
B) when an neutron transforms into a proton, an electron is produced
Explanation:
The both are nuclear decay processes which produce a neutrino and tremendous energy. The conversion of protons to neutrons is an energetically difficult process. However, the conversion of neutrons to electrons is commonly called beta decay in nuclear physics.
