The diagram shows two bar magnets. They are cut along the dashed line, and then the two marked ends are placed near each other. Which statement best explains how the pieces will react?
A) The pieces will repel because the cut end of the top magnet is not a magnetic pole.
B) The pieces will attract because the cut end of the top magnet is not a magnetic pole.
C) The pieces will repel because the cut end of the top magnet is a south pole.
D) The pieces will attract because the cut end of the top magnet is a north pole.
Answers
The answer to this problem is "OPTION C" i.e. The pieces will repel because the cut end of the top magnet is a south pole.
A magnet as a collection of tiny magnets, called magnetic domains. Each of these domain reinforces the magnetic fields of the other domains and hence the net magnetic field of magnet is generated. Each one of these domains have a tiny north and south pole. If you cut a magnet in half (along the line suggested in the problem), the newly cut faces will become the new north or south poles of the divided parts.

Answers
The piece of information that is missing for the correct calculation of velocity is the direction.
What is velocity?
Velocity is the rate of change of distance. Velocity is a vector quantity. A vector quantity depends on magnitude and direction as well.
If forward direction, then velocity would be positive and if backward direction, it would be of negative.

Pressure
Is a measure of how much force is applied perpendicular over a given area.
It is calculated by dividing the amount of force being applied F by the area over which it is being applied A:
The SI unit for pressure is the Pascal (Pa), equivalent to
A pressure of 300 Pa is being exerted over an area that experiences a force of 6000 N. We are required to calculate the value of the area.
If we know the pressure and the force, we solve the above equation for A;

Converting from feet to meters using the equation:
1 ft = 0.3048m
10 ft = 3.048m
Multiplying that by 30 storeys, we get:
3 x 3.048m = 91.44m, which is near the answer of (3) 10^2 m or 100m.

Answer: The correct answer is option a.
Explanation:
Basic unit to measure mass is defined as the unit which is commonly used to measure the mass of an object.
From the given options,
Option a: Grams is a unit which is used to measure mass and it is the commonly used unit.
Option b: Cubic meter is the unit which is used to measure the volume of an object.
Option c: Metric ton is a unit which is used to measure the mass of an object but this unit is not commonly used. hence, this is not basic unit to measure mass.
Option d: Meter is the unit which is used to measure length.
From the above information, the correct answer is option a.
