Here in nuclear reaction we can say that sum of neutrons and protons in reactant side and product side will be same always
Here mass number on the product side is given to us
so sum of mass number is given as

now on the reactant side also the number must be same

now we will have


Now number of protons on product side is given as

now we also know that atomic number of Fe is 26
so now we will have



now the equation is given as

If a mass of a neutron is 1 the electron mass is 0.00054386734 and it's charge is negative. Hope this helps! ;)
Answer:
C) specific heat capacity
Explanation:
As we know that heat given to the system to change the temperature is given as

here we know that
Q = thermal energy given to the system
s = specific heat capacity of the system
= change in temperature
so here we know that

here we know that heat given to the two cubes is of same amount as well as the mass is same but the final temperature is different because of the specific heat capacity (s)
So correct answer would be
C) specific heat capacity
The temperature where vapour pressure equals atmospheric pressure is called BOILING POINT. This vapour pressure increases with rise in temperature. Also boiling point is different for different liquids. Hope I cleared your doubt...
You take 3 steps east, turn around & take another 7 steps west (4 steps always from origin) you turn around again and take 6 more steps east - 2 steps always from origin
