<span>Answer: V/n = constant</span>
Hey mate!
A white shirt is always cooler in sunlight.
Hope it helps
We know from the physics class that the time is simply the
distance divided by velocity:
time = distance / velocity
Substituting the given values and calculating for time:
time = 360 km / (72 km / hour)
time = 5 hours
<span>Therefore it takes the train 5 hours to arrive.</span>

D. MgF₂
Explanation:
The compound that is held together by the electrostatic force between two ions is MgF₂.
Electrostatic force of attraction is exhibited primarily and only in ionic compounds.
In this type of bond;
- A metallic atom such as Mg will lose two of its valence electrons to form Mg²⁺
- Two non-metal ion that is highly electronegative such as "F" will gain the two electrons because they require an electron each to have a perfect octet.
- Two ions are now formed.
- In the vicinity of one another, they attract with an electrostatic force.
- This is why our answer is MgF₂.
- Electrostatic force occurs in ionic/electrovalent compounds
