Aball rolled down a 6 m hill in three seconds. what was the balls speed in m/s2?

2 meters per second. I strongly think that this is the answer since the digit 6 needs to be divided by 3 due to the fact that they are the only numbers in this problem

Mg-26 and mg-24 are pair of isotopes. isotopes are defined as atoms of the same element having same atomic number but different mass number. i hope that was .
