Calculate the specific heat capacity of a piece of wood if 783.35 g of the wood absorbs 35,250 joules of heat, and its temperature changes from 82°C to 107°C.

- 5.2 J/gºc
- 1.8 J/gºc
- 2.9 J/gºc
- 0.5 J/gºc

there is none because earth is stationary and flat.

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
