neutrons
Explanation:
Isotopes of an element differ in their number of neutrons.
Isotopy is the existence of two or more atoms of the same element having the same atomic number but different mass numbers due to the differences in the number of neutrons in their nucleus.
- Isotopes of an element have the same electronic configuration.
- They have the same chemical properties but differ in their masses.
- The mass of an atom is function of the protons and neutrons.

D. write down the coefficients
The answer for this question is: C
Answer:
50N
Explanation:
Since the floor is frictionless, the net force = mass × acceleration.
given that,
mass = 10kg
and acceleration is 5 m/s²
Thus,
Force = 10 × 5
Force = 50 N
