Explanation

An n-type semiconductor results from implanting dopant atoms that have more electrons in their outer (bonding) shell than silicon. 

Explanation

Most  eucalyptus trees grow much faster than other trees

Some eucalyptus species can grow 6 to 12 feet per year. 

Eucalyptus trees thrive in warm climates with sufficient water and sunlight. 

Eucalyptus trees are widely cultivated for their timber, essential oils, and ornamental value.

Explanation

Soil fertility can be maintained without adding extra nutrients due to microbial activity.

Microbes increase the amount of nutrients in the soil that are available to plants

Explanation

A dipole in an electric field behaves in two ways:

• In a uniform electric field:

The two equal and opposite forces cancel each other out.

So, the net force on the dipole is zero.

But a torque is produced that tends to align the dipole moment parallel to the electric field.

• In a non-uniform electric field:

The dipole does experience a net force, and that force is generally not simply parallel to the field.

So the correct answer remains:

(D) None of these — because in a uniform electric field, the net force on a dipole is zero.

Option (C) would be correct only if we were talking about torque direction or net force in a non-uniform field.

Explanation

An apiary is a place where bees are kept.

It typically for beekeeping and honey production.

It consists of multiple beehives maintained by beekeepers.

Explanation

Physiotherapy, is a healthcare profession that focuses on the assessment, diagnosis, and treatment of disorders and injuries that affect the physical function of the body.

Physiotherapists work to restore, maintain, and maximize a patient's strength, function, movement, and overall well-being.

Physiotherapy typically deals with:

• Immobility of joints and muscles
• Injuries or conditions affecting the musculoskeletal system (e.g., back pain, arthritis, sports injuries)
• Neurological conditions (e.g., stroke, spinal cord injury, Parkinson's disease)
• Cardiovascular and respiratory conditions (e.g., heart disease, chronic obstructive pulmonary disease)

Explanation

To find the self-inductance of a coil, we can use the formula:

L = (ΔΦ / ΔI)

Where:

L is the self-inductance in Henry (H),

ΔΦ is the change in magnetic flux in Weber (Wb),

and ΔI is the change in current in Ampere (A).

In this case, the current changes from 5A to 0A (nil) in 5 seconds. (ΔI) is therefore 5A - 0A = 5A.

To find the change in (ΔΦ), we can use Faraday's law of electromagnetic induction

ΔΦ = L * ΔI

Since the current changes from 5A to 0A in 5 seconds, the rate of  (ΔI) is 5A / 5s = 1A/s.

Substituting the values into the equation:

ΔΦ = L * ΔI

500 V = L * 1 A/s

Since the (V) is equal to  (L) and  (ΔI), we can rewrite the equation as:

L = 500 V / 1 A/s

Simplifying the equation gives us:

L = 500 H

Therefore, the self-inductance of the coil is 500 Henry (H).

Explanation

Capillary action is the process of a liquid flowing in a narrow space without the assistance of, or even in opposition to, any external forces like gravity.
