Answer:

(B) tightly packed protons and neutrons

Explanation:

  • Nucleus of any atom is the dense central part of any atom.
  • It consists of two sub-atomic particle namely proton and neutron.
  • These sub-atomic parts are tightly packed in nucleus which makes the nucleus dense .
  • This dense nucleus is responsible for most of the mass of atom.
  • The atomic mass for any atom is decided by sum of  the mass of proton and neutron

Thus, correct answer is

(B) tightly packed protons and neutrons

if a spring has a spring constant of 2 N/m and it is stretched 5 cm, what is the force of the spring?
djyliett [7]

Answer:

0.1 N

Explanation:

Considering the relationship between force,

spring constant and extension as defined by Hook's law

The force F=xk as from Hooke's law where F is the force of the spring, k is spring constant and x is extension or compression. Substituting 2 N/m for k and 5cm which is equivalent to 0.05 m for extention x then the force will be

F=2*0.05=0.1 N
