The diagram best shows the magnetic field around the bar magnet is the diagram in option B.
<h3>What is the magnetic field?</h3>
The magnetic field refers to the region in space where the influence of a magnet can be felt. We know that strength of magnet can be seen by following the magnetic lines of force. The more the magnetic lines of force, the stronger the magnetic field especially when the line are packed closely together.
Looking at the diagrams of the magnetic lines of force, it must be recalled that the magnetic lines of force runs from the north pole to the south pole and not the other way round.
Thus, the diagram best shows the magnetic field around the bar magnet is the diagram in option B.

Answer:
500N/m²
Explanation:
The Pressure can be calculated using the formula:
P = F/A
Where;
F = force (N)
A = Area (m²)
Based on the information provided in the question, F = 30N, A = 0.06m²
P = F/A
P = 30/0.06
P = 500N/m²
Atomic mass (K)= 39.1 amu
therefore:
1 mol (k)---------------------39.1 g
x------------------------------- 2.25 g
x=(1 mol * 2.25 g) / 39.1 g=0.05754....≈0.06 moles
Answer: 0.06 moles.
Answer:
2Mg + O2 → 2MgO
Explanation:
In all conbustion you should know, that reactans are an specific compound and O2, so the products must be CO2 and H2O, or in this case, the corresponding oxide.
