The best way is: B. flat, so that the north pole of the magnets on the train point up and the north poles of the magnets on the track point down.
<h3>What is the law of magnetism?</h3>
The law of magnetism states that the like poles of a magnet repel one another while unlike (different) poles attract each other. Thus, two north (N) poles of a magnet would repel one another while a north (N) and south (S) would attract each other.
Based on the law of magnetism, the best way to arrange the magnets on the train and on the track, so as to allow the model train levitate is flat, as this would make the north (N) pole of the magnets on the train point up and the north (N) poles of the magnets on the track point down.

Explanation:
I see us in the park strolling in the summer haze...
Answer:
Amount to spend = $18.50
Purchased banana =$1.50
Apple Juice =$1.55
Gasoline $2.35
$1.50 + $1.55 = $3.05
18.50 - 3.05 = 15.45
1 Gallon of Gasoline = 2.35
Therefore,
2.35 x 6 = 14.1
15.35 - 14.1 = 1.25
To avoid exceeding budget, he can only buy
6 gallons of gasoline
The present value (PV) of $15,254.24 is the most James bennett can consume in his youth.
<u>Given the following data:</u>
- Investment opportunity (youth) = $12,000
- Investment opportunity (old age) = $15,000
To calculate the most James bennett can consume in his youth:
First of all, we would determine the future value of James bennett from his investment and inheritance as follows:

FV = $18000
Mathematically, the most James bennett can consume in his youth is given by this formula:

Substituting the given parameters into the formula, we have;

PV = $15,254.24
Therefore, the present value (PV) of $15,254.24 is the most James bennett can consume in his youth.
