I think the first question is talking about the ionic compound Sodium sulfide and it’s formula is Na2S.
And for the second question, i’m pretty sure it’d be a positive charge
It is to conduct electricity in the magnet so it has an electric field.

The average kinetic energy of the molecules of the coffee will decrease and the speed of the individual molecules will also reduce.
<h3>
Temperature of resultant mixture</h3>
The temperature of the resultant mixture will be higher than the cold water temperature and lower than the hot coffee temperature.
Based on the decrease of the resulting temperature (equilibrium temperature) of the mixture, the average kinetic energy of the molecules of the coffee will decrease and the speed of the individual molecules of the hot coffee mixture will reduce, leading to a resultant cold mixture of coffee.

Answer:
maximum speed of the elevator is 6.54 m/s
Explanation:
given,
force exerted on the elevator is 1.59 times passenger weight.
when the elevator accelerates upward with rate of a.
total force
F = m × (a+g)
1.59× mg = ma + mg
0.59 mg = ma
a = 0.59 g
we also have that
=
= 6.54 m/s
maximum speed of the elevator is 6.54 m/s
Answer:
Tempered glass
Explanation:
When warmed, an amorphous substance has a non-crystalline architecture that differentiates from its isochemical liquid, but this does not go through structural breakdown or the glass transition.
