Answers
Every magnet has two unlike poles.
The neutral region within a magnet lies between the north and south poles.
If the north pole of a bar magnet is brought near the north pole of another magnet, the two magnets will repel one another.
A material that's attracted by a magnet but doesn't necessarily become a magnet itself is called a ferromagnetic material.
What is magnet?
A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc. and attracts or repels other magnets.
What are properties of magnet?
- Magnet will attract ferromagnetic substances.
- Like poles of the magnet repel each other and unlike poles attract each other.
- A suspended magnet always comes to rest in the north-south direction.
- The poles of the magnet are in pairs.
What is Ferromagnetic materials?
Ferromagnetic materials are those materials which exhibit a spontaneous net magnetization at the atomic level, even in the absence of an external magnetic field. When placed in an external magnetic field, ferromagnetic materials are strongly magnetized in the direction of the field.

B) 37 V
The potential difference between point a and point b is equal to 37 V
Explanation:
The potential difference across a and b can be calculated by finding the equivalent resistance of the resistors R1, R2 and R3 and then by applying Ohm's law.
Given:
R1 = 3.0 Ω
R2 = 8.0 Ω
R3 = 10.0
Current = I = 5 A
To calculate equivalent resistance of the circuit:
R2 and R3 are connected in parallel configuration. The equivalent resistance of R2 and R3 can be calculated as
Resistance R1 is in series with Rp. The equivalent series resistance is calculated as
Thus the given 3 resistor circuit can be written as an equivalent resistance Rs equal to 7.44 Ω through which current I passes.
By Ohm's law;
If V is the potential difference between a and b
Potential difference across points a and b = Current flowing through the circuit × Resistance between points a and b
37.2 V ≈ 37 V
Therefore, the potential difference between point a and point b is equal to 37 V

handle with a force of 87 N, how much work is done?
Answers
The work done on the wagon is 3549 J
Explanation:
The work done by a force when moving an object is given by
where:
F is the magnitude of the force
d is the displacement
is the angle between the direction of the force and of the displacement
In this problem we have the following data:
F = 87 N is the magnitude of the force
d = 44 m is the displacement of the wagon
is the angle between the direction of the force and the displacement
Substituting, we find the work done

A possible dependent variable is the tomatoes, the amount of time you cook them (assuming thats what you're supposed to do) the temperature, etc, what you need to keep the same.
I'm unsure of the constants though, sorry. Hope this helped a bit!
