An investigation involves determining which metal is better for making pots that will cook food faster. choose the best hypothesis to use for this investigation.

a.) copper is better than iron for making pots.
b.) copper is more malleable and heats up faster than iron.
c.) if copper is a better conductor, it will heat up faster than iron.
d.) if copper heats up faster than iron, it is better for making pots.

they all get energy from eating other animals, dead animals to be more precise.

hienas tends to steal pray from other animals. crows and vultures tend to eat dead animals and leftovers.

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.
