From the above diagram, the collision between two objects A and object B would be Correct Answer oblique collision

Correct option-2

Concept:

Collision-

  • The meaning of the term ‘collision’ in our everyday life  ‘striking’, in physics it does not necessarily mean one particle striking against another.
  • Indeed two particles may not even touch each other and may still be said to collide.
  • A collision occurs when two bodies come in direct contact with each other.
  • In this event, two or more bodies exert forces on each other in about a relatively short time.
  • The collision is in fact a redistribution of the total momentum of the particles

Types of collisions:

On the basis of direction, the collisions are of two types-

1. One-dimensional collision or Head-on collision: 

A collision in which the colliding particles move along a straight line before and after the collision.

Types of Collision on the basis of kinetic energy conservation:

The law of conservation of momentum holds true in the collision between two masses but,

there may be some collisions in which Kinetic Energy is not conserved.

Depending on energy conservation, Collisions are basically of two types:

1. Elastic Collision: ​

  • In the elastic collision total momentum, total energy, and total kinetic energy are conserved.
  • Although, the total mechanical energy is not converted into any other form of energy as the forces involved in the short interaction are conserved in nature.


2. Inelastic Collision:

  • In the inelastic collision, the objects stick to each other or move in the same direction.
  • The total kinetic energy of the system containing colliding objects is not conserved but the total momentum and energy are conserved.
  • During Inelastic collision, the energy is transformed into other energy forms like heat and light.

3.Perfectly plastic collision:

  • The collision in which particles get stuck together after the collision.
  • The loss is energy is maximum in this collision.

How does a host on an Ethernet LAN know when to transmit after a collision has occurred?
1. In a CSMA/CD collision domain, multiple stations can successfully transmit data simultaneously.
2. In a CSMA/CD collision domain, stations must wait until the media is not in use before transmitting.
3. You can improve the CSMA/CD network by adding more hubs.
4. After a collision, the station that detected the collision has first priority to resend the lost data.
5. After a collision, all stations run a random backoff algorithm. When the backoff delay period has expired, all stations have equal priority to transmit data.
Directions: Seven different boxes A, B, C, D, E, F and G of different colours viz., Orange, Pink, Purple, Yellow, Blue, Red and Green are arranged one above the other. The box at the bottom of arrangement is numbered 1, the above box is numbered 2 and so on. B is immediately above E. More than two boxes are above the Orange box. The Yellow box is immediately below A. Only one box is between the Orange box and F. G is immediately above the Red box. Only one box is between B and the Pink box. Only two boxes are between the Pink and the Green box. Only two boxes are between the Yellow box and the Orange box. The Purple box is neither at the top nor at the bottom of the arrangement.B is above Pink box. C is immediately above F. Neither C nor G is a Yellow box. G is not a Orange box.
