Explanation

Our solar system takes approximately 250 million years to complete one orbit around the Milky Way galaxy.

Explanation

Dogs can hear sounds in the range of 67 Hz to 45,000 Hz, which is slightly higher than the human audible range.

Explanation

AM (Amplitude Modulation) radio operates in the frequency range of 550 to 1700 KHz.

Explanation

All non-zero digits and zeros between or after decimals are significant.

In 1.00110, all six digits (1, 0, 0, 1, 1, 0) are significant.

Explanation

A longitude is an imaginary line that runs vertically from the North Pole to the South Pole.

These lines, also called meridians, measure the distance east or west of the Prime Meridian.

Explanation

The standard deviation is a measure of the dispersion or spread of a set of data points.

It is independent of changes in both the origin (the mean or average value) and the scale (the units of measurement). 

Explanation

The electric potential at a point due to a point charge 

The formula gives Q:𝑉=𝑘/𝑄𝑟

Where:

V is the electric potential,

k is Coulomb's constant,

Q is the charge, and

r is the distance from the charge to the point where the potential is being calculated.

In this case, there are two charges: +5μC at point A and −5μC at point B.

The electric potential is a scalar quantity, meaning it can simply be added algebraically.

Explanation

Opaque objects form sharp and dark shadows because they block all light from passing through, creating a clear and defined shadow.

Explanation

• Weight is a force.
• The unit of measurement for force is the Newton (N).
