Answer:
a structural variation in which different atoms of the same element have different numbers of neutrons
Explanation:
An isotope is an atom of an element having the same number of protons but different number of neutrons. Different isotopes are used for different purposes. Example: some are used in medicines , food irradiation, etc.
Carbon has three isotopes C 12, C 13, C 14. All three of them have 6 protons but have different numbers of neutrons.

C 13 is less abundant than C 12
C 14 is used for dating fossils . It is radioactive
Answer:
Explanation:
If a rocket (firework) is launched
with an initial velocity of 39.2 meters per second at a height of 1.6 meters above
the ground, the equation h = -4.9t2
+ 39.2t + 1.6 represents the rocket’s height h in
meters after t seconds. The rocket will explode at approximately the highest point.
Fire official require the fireworks to explode at a height greater than 76 feet in
order for debris to land in Lake Michigan and not on the festival sight. The event
planners assured the fire officials that the fireworks would reach a height greater
than 76 feet
