Explanation

All the isotopes of the same element have the same number of protons, which defines the element.

Different isotopes can exist depending on the neutron count.

Electrons are negatively charged and can counterbalance the positive charge of protons.

Also, they are present in equal numbers in neutral atoms of the same element.

Explanation

When two resistances are connected in parallel, the net resistance (Rnet) is calculated using the formula:

1/Rnet = 1/R1 + 1/R2

where R1 and R2 are the individual resistances.

In this case, R1 = 6 Ω and R2 = 12 Ω, so:

1/Rnet = 1/6 + 1/12 = 1/4

Rnet = 4 Ω

Therefore, the net resistance of the two resistances connected in parallel is 4 Ω.

Explanation

Electrostatics is the branch of physics that deals with the study of stationary electric charges, also known as static electricity.

It involves the study of electric charges at rest, their properties, and the forces that act upon them.

Explanation

In the ball and bowl system, the mean position (also known as the equilibrium position) is at the center of the bowl.

This is the position where the ball comes to rest when it is not disturbed.

Explanation

Amino acids are the building blocks of proteins, which are long chains of amino acids linked together by peptide bonds.

There are 20 different amino acids that the human body uses to build proteins.

They are essential for various cellular processes, including structure, function, and regulation.

Explanation

Glucose (C6H12O6) is a type of carbohydrate, specifically a simple sugar or monosaccharide.

It is a vital source of energy for many living organisms, including humans.

Glucose is a primary component of many carbohydrates, such as starch, cellulose, and glycogen.

Explanation

Homozygous refers to the state where an individual inherits two identical copies of a gene (one from each parent) that code for the same trait or characteristic.

Explanation

The larynx (voice box) is located on top of the trachea (windpipe), which is a tube that leads to the lungs.

The larynx sits at the junction of the pharynx (throat) and the trachea, and it plays a crucial role in speech and breathing.

Explanation

Protium (1H) is the lightest isotope of hydrogen, and it has no neutrons.

Its atomic nucleus consists of only one proton.

• Protons: 1
• Neutrons: 0
• Electrons: 1

Explanation

A turn ratio of 10 means that the secondary coil (Ns) has 10 times more turns than the primary coil (Np).

This is a step-up transformer, which increases the voltage and decreases the current.
