Question

03. Find the odd one out
1) Frictional force, Electro-static force, Magnetic force, Gravitational force
2) Volvox, Paramoecium, Euglena, Staphylococcus Aureus
3) Malaria, Dengue, Hepatitis, Elephantiasis
4) Gold, Silver, Copper, Brass​

Answer 1

Answer:

1 - frictional force.

3 - hepatitis.

4 - brass

Answer 2

Answer:

Explanation: The odd one among the forces is friction because friction is a contact force while electrostatic force, gravitational force and magnetic force are non-contact forces. It means friction requires contact with the surface to move objects in the opposite direction, such as walking and writing.
