Answer:
Explanation:
chemical properties of isotopes are different . but their valencies are same so the gain or lose electrons the same
Answer:
Total resistance is 19.6 Ω for the circuit .
Explanation:
Given:
Six resistors of a circuit namely to .
Where
and are in series.
and are in parallel.
and are in parallel.
We know that continuous resistor which are in series are added up to find the equivalent resistance.
Similarly resistors which are arranged in parallel their equivalent resistance is for the case of and .
According to the question:
Total resistance = R(equivalent) :
⇒
⇒
⇒
⇒
⇒ Ω
So the total resistance of the circuit depicted is 19.58 Ω approximated to nearest tenth that is 19.6 Ω
There is a limited amount of energy in the universe since it cannot be destroyed or created only transferred. This being said, eventually the universe will have expanded to vastly that all of its energy will be spread too thin for any form of life to be possible.
