Which statement correctly describes protons? A. They have no charge and are present in the nucleus of an atom. B. They have a ne
gative charge and travel around the nucleus of an atom. C. They have a positive charge and travel around the nucleus of an atom. D. They have a positive charge and are present in the nucleus of an atom along with the neutrons.
1 answer:
It is known that atoms are formed by protons, neutrons and electrons. Research has shown that each of these particles have charge.
-The electrons have negative carge
-Protons have a positive charge
-Neutrons have a neutral charge.
The currently accepted atomic models describe the atom as a nucleus formed protons and neutrons, with electrons orbiting around this nucleus as shown in the attached image.
Therefore the correct option is. D. They have a positive charge and are present in the nucleus of an atom along with neutrons.

Answer:
2.5m/s^2
Explanation:
Step one:
given
distance = 20meters
time = 2 seconds
initial velocity u= 0m/s
let us solve for the final velocity
velocity = distance/time
velocity= 20/2
velocity= 10m/s
divide both sides by 40
