1 answer:
-5m/s
Explanation:
Given parameters:
Speed of the car = 20m/s
Time taken = 4s
Unknown:
Average acceleration = ?
Solution:
Acceleration is the change in velocity or speed with time of a body.
Acceleration =
v is the final velocity = 0
u is the initial velocity
t is the time
Input the values:
Acceleration =

Answer: The net change in the atoms is the conversion of a neutron to a proton, turning Carbon (6 protons) into Nitrogen (7 protons).
Explanation:
Carbon-14, generated from the atmosphere, has 6 protons and 8 neutrons. That's where the 14 comes from, called the mass number, is the sum of protons and neutrons (6+8=14).
Carbon-14 is radioactive and decays by beta decay. That means one of its neutrons spontaneously turns into a proton, an electron, and a neutrino, according to:
After that, the atom has 7 protons and 7 neutrons, maintaining its mass number but changing its atomic number from 6 to 7, turning into Nitrogen.
