Answer:
NaNO3.
Explanation:
The Na ion has one positive charge and the NO3 ion has one negative charge so the correct formula is NaNO3.
Answer:
13.33 or 13 1/3m/s (meters per second)
Explanation:
In physics, we use the basic units of meters and seconds. So first convert (km) into meters (m) and also hours and minutes into seconds (s). We end up with 120000m and 9000s. Then divide the 120000m by the 9000s and you end up with 13.33 or 13 1/3 m/s.
Answer:
Centripetal force is the force that keeps the yoyo going in a circle, if the string breaks, the yoyo would would fly off in a direction that is different to the point on the circle.
The force the escaping gas exerts of the rocket is 10.42 N.
<h3>
Force escaping gas exerts</h3>
The force the escaping gas exerts of the rocket is calculated as follows;
F = m(v - u)/t
where;
- m is mass of the rocket
- v is the final velocity of the rocket
- u is the initial velocity of the rocket
- t is time of motion
F = (0.25)(40 - 15)/0.6
F = 10.42 N
Thus, the force the escaping gas exerts of the rocket is 10.42 N.

Explanation:
London dispersion forces will form between non-polar molecules(polar ) that are symmetrical like O₂, H₂, Cl₂ and noble gases.
- The attraction here is because non-polar molecules becomes polar due to the constant motion of its electrons.
- This lead to an uneven charge distribution at an instant.
- A temporary dipole or instantaneous dipole forms.
- The temporary dipole can induce neighboring molecules to be distorted and forms dipoles as well.
- This forms london dispersion forces.
