Amagnetwith alength of 10cmwasgiven to Meera and shewas told to break themagnetinto3 pieces.Before breaking the magnet had 1 north and 1 south pole. How many north and south poles will the magnets now havetotally in all the 3 broken pieces?

Answers

Answer:

3 North poles and 3 South poles

Explanation:

A magnet is a piece of object that produces a magnetic field outside itself. A magnet has a north pole and a south pole. Similar poles repel each other, while opposite poles attract each other.

If a magnet of 10cm is broken into 3 pieces, we will have 3 pieces of magnet. Breaking a magnet does not destroy the properties of the magnet. Rather, each piece becomes a full magnet with both north and south poles.

Breaking a 10cm magnet will give us 3 magnets with 3 north and 3 south poles with equal pole strength.

what is the molar mass of Br2 in grams

Answers

Answer:

159.808 g/mol

Explanation:

Br itself is 79.904 g/mol. So multiply it by two.

The molar mass of [tex]Br_{2}[/tex] is approximately 159.808 grams per mole.

When calculating the molar mass of [tex]Br_{2}[/tex], also known as diatomic bromine, the atomic masses of the two bromine atoms (Br) found in the molecule are added together.

Bromine (Br) has a mass of roughly 79.904 grammes per mole according to its atomic weight.

Because of this, the molar mass of [tex]Br_{2}[/tex] is calculated as follows: 2 times 79.904 g/mol = 159.808 g/mol

As a result, the amount of grammes that constitute one mole of [tex]Br_{2}[/tex] is roughly 159.808.

Protein synthesis is the generation of proteins by cells that employ DNA, RNA, and different enzymes.

What is protein synthesis?

It generally includes transcription, translation, and post-translational events, such as protein folding, modifications, and proteolysis the process of protein synthesis.

the mRNA contains the sequence of nucleotides transcribed from the DNA that defines the sequence of amino acids that a synthesized protein will have.

In mRNA, codons are triplets of nitrogenous nucleotides that code for amino acids and using ribosomes mark the beginning and end of protein synthesis.

Therefore, in contrast to mRNA codons, anticodons are triplets of nucleotides found in transfer RNA (tRNA). The linking of amino acids to the polypeptide chain being produced is carried out by tRNA.

O At the bottom of the long plastic tube
O At the bottom of the short plastic tube

Answers

Answer:

The answer is third example

At the bottom of the short plastic tube metal cylinders located when they had the Most gravitational potential energy.

What is Gravitational potential energy?

The energy that an object has due to its location in a gravitational field is known as gravitational potential energy.

When an object is close to the surface of the Earth, when the gravitational acceleration can be assumed to remain constant at roughly 9.8 m/s2, gravitational potential energy is most frequently used.

The potential energy at a height h above that point is equal to the effort that would be needed to raise the object to that height with no net change in kinetic energy because the zero of gravitational potential energy can be chosen at any location.

Therefore, At the bottom of the short plastic tube metal cylinders located when they had the Most gravitational potential energy.
