Question

write short notes on diffrent types of bacteria
explain clearly ​

Answer 1

Explanation:

Hint: Collisions – define it in terms of the laws of conservations they follow. Explain the types of collision based on the conservation laws they followed. Use the law of conservation of momentum and the law of conservation of kinetic energy in an elastic collision to develop the theory of one-dimensional elastic collision.

Complete step-by-step answer:

Collision can be defined as the event in which two moving bodies or one moving body and one at rest collide with each other.

Collision is of two types –

1. Elastic collision

2. Inelastic collision

Elastic collision can be defined as a collision where the total kinetic energy of the system is conserved. In an elastic collision both the total kinetic energy and the total linear momentum of the system remains constant.

In an elastic collision the total kinetic energy of the system will not be conserved. The total kinetic energy before the collision and after the collision will be different.

Consider two bodies, one with mass

m

1

m1

moving with velocity

v

1

v1

in the positive x-direction and another body of mass

m

2

m2

at rest.

Answer 2

Answer:

Bacteria are the plural of bacterium, which are microscopic one-celled organisms. They are found everywhere and can be harmful, as in infections; or they can be beneficial, as in fermentation or decomposition. Five types of bacteria are:

Coccus, Bacillus, Spirillum, Rickettsia, and Mycoplasma.
