When a gas is heated to become a plasma, the atoms (or the molecules) of the gas become ionised. In the ionisation, the atoms loose electrons from the exterior energy levels and thus heating to achieve a plasma will create free electrons and ionized atoms (or ionized molecules).
A plasma can not contain neutrons, because neutrons together with protons make the nuclei of the atoms. To free the neutrons from the atomn nuclei there would be necessary HUGE temperatures.
Also a plasma does not contain neutral elements (atoms) or (neutral) molecules, but Ionized atoms and/or molecules and free electrons.
Thus the good answer is d)
Answer:
1000kg
Explanation:
We can use the equation "p=mv"
- p is the momentum in kg m/s
- m is the mass measured in kg
- v is the velocity measured in m/s
If we rearrange the equation to find mass (m), then the equation becomes:
m=p/v
We can substitute in the values of p and v as they are already given in the question.
So, now we just substitute in the values to get our answer.
m=p/v
m=25,000/25
m=1000kg
Answer: "The groups had evolved into separate species. "

Answer:
1.)The bob of pendulum should be displaced with a small angle.
2) The amplitude of the oscillation of a simple pendulum should be small.
3) Fans should be switched off to reduce the air resistance.
4)The simple pendulum should be oscillate in a vertical plane
