An atom is the smallest unit of an element
As more bulbs are added in parallel, the current strength will decrease OR. As more bulbs are added in parallel, the current strength will increase.
Gravitational Potential of an object with mass m, and height of h metre is :
Now, if the mass of object is 2100 kg, height of 18 m is placed in there, then it's gravitational potential energy is ~
Answer: C) the energy gained by an electron in moving through a potential difference of 1 volt
Explanation: In order to explain this response we have to consider that the potential energy for any charge is given by:
Up=q*ΔV then if we consider an electron accelerate by a difference potential of 1V, we have:
Up=e*V ( energy UNITS, which is equal to 1.6*10^-19 J).
The option A) and B) are wrong because elentron Volt has units of energy not force.
The option D) is also wrong because the the work done to move un electron one meter also depends of the magnitud of the potential difference ( electric field) where the electron is moving .
Finally the option D) is false because the one C*V is one J, is huge quantity of energy compared to the electron Volt (eV).
The answer to this is CP Air Mass. cP stands for Continental Polar Air Mass. This is the type of air mass that comes from Northern Canada. This kind of air mass is cold, having a little moisture only and you can expect cold seasons during the months of winter.
