Answer:
These two forces are called action and reaction forces and are the subject of Newton's third law of motion. Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction.
A magnet is an item or substance that generates a magnetic field. The broken pieces of the magnet will have 4 poles.
A magnet is an item or substance that generates a magnetic field. This magnetic field is invisible, but it is responsible for a magnet's most remarkable property: a force that attracts or repels other ferromagnetic elements such as iron, steel, nickel, cobalt, and others.
When a magnet is broken into two pieces, it produces two complete magnets, each with its own north and south poles and the same orientation as the original.
For example, if you break a 12-inch bar magnet with N on the left end and S on the right end midway between the two ends, you'll get two magnets with N on the left end and S on the right end, as seen in the illustration below.
Hence, the broken pieces of the magnet will have 4 poles.

Answer:
a) NaOH volume at the equivalence point is 100 ml.
b) NaOH volume at the equivalence point is 45 ml.
Explanation:
To calculate the concentration of acid, we use the equation given y neutralization reaction:
where,
are the n-factor, molarity and volume of acid.
are the n-factor, molarity and volume of base
a) If a 0.100 M NaOH (aq) solution is used to titrated with 50.0 mL of 0.200 M HBr(aq).
We are given:
Putting values in above equation, we get:
b) If a 0.100 M NaOH (aq) solution is used to titrated with 30.0 mL of 0.150 M (aq).
We are given:
Putting values in above equation, we get:
D is the correct answer.
Heat transfer between two objects happens when energy transfers from the hotter object to the colder object until they reach thermal equilibrium. This can happen through conduction, convection, and radiation.
The transfer of heat between two objects is best explained by the principle that energy is transferred from the hotter object to the colder object, and this occurs until both objects have reached the same temperature. This transfer of heat energy happens primarily through three processes known as conduction, convection, and radiation.
Conduction is the transfer of heat between two objects in direct contact with each other, such as a hot pan warming up food. Convection is the transfer of heat due to the movement of mass, typically within fluids like air or water. Radiation is the transfer of heat through electromagnetic waves, like the heat you feel from the Sun on a sunny day.
When two objects of different temperatures come into contact, like object X with temperature Tx and object Y with temperature Ty, heat flows spontaneously from the hotter object X to the colder object Y. This results in a loss of thermal energy in X and a gain in thermal energy in Y, until both reach a state of thermal equilibrium.
