Explanation

The time rate of change of magnetic flux has the same dimensions as that of potential difference (or electromotive force - EMF). 

Explanation

Kinetic Energy (K.E) = ½ × mass × velocity² = ½ × 2 × (4)² = 1 × 16 = 16J

The formula directly gives 16 joules for the given mass and velocity.

Explanation

Input, processing, output, and storage are the four primary components of the information processing cycle.

It is also known as the data processing cycle or the computer processing cycle.

Explanation

An ammeter is always connected in series to measure the current flowing through a particular branch of the circuit.

This allows the ammeter to measure the entire current flowing through that branch, providing an accurate reading.

Explanation

The SI unit of velocity is a ms^-1 and m/s.

Explanation

Summer Solstice happens once every year. 

Summer Solstice is on 21 June, also known as the longest day of the year.

22 December night is the longest night of the year.

Explanation

Minerals are raw materials used to make coins, wires, and jewelry due to their physical properties.

Vegetables are living plants and are not made from minerals.
