Explanation

Red light rays have the lowest frequency and highest wavelength value.

Blue or violet light has the shortest wavelength.

Explanation

The melting point of ice at normal atmospheric pressure is 0 °C (zero degrees Celsius).

Key Points:

• 0 K (zero Kelvin) is equivalent to -273.15 °C, which is absolute zero, the lowest possible temperature.
• 100 °C is the boiling point of water at normal atmospheric pressure.

Israel launched a polio vaccine drive after 1988 in April 2022

Explanation

ATP (Adenosine Triphosphate) is called the energy currency of the cell because it stores and provides energy for cellular activities.

It releases energy when converted to ADP (Adenosine Diphosphate), which is then recycled back into ATP through cellular respiration.

Explanation

Light is a form of energy.

Light is actually energy made of small particles called photons.

Explanation

Explanation

Artificial Intelligence is a branch of Computer science, which aims to create intelligent machines so that machine can think intelligently in the same manner as a human does.

Note: John McCarthy is recognized as the father of Artificial Intelligence due to his astounding contribution in the field of Computer Science.

John McCarthy was an American computer scientist
