Ahectare (10,000 m2) is a metric unit of area analogous to an acre. how many square centimeters are in a 5 ha farm?

Explanation:

First you put in order the information the problem gives you:

* 1 ha = 10000

* The farm has 5 ha

Then you use a conversion factor:

1)* The farm has 5 ha:

2) Multiply by the equivalence of ha in meters:

3) Solve:

Finally you should convert from to square centimeters ,so:

one state would change   like louisiana to texas. thats a change

explanation:

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
