Average speed is greater than average velocity. Average velocity is zero.
Average speed is calculated by:
Distance is the length of the total path traveled.
Average velocity is given by:
Displacement = final position - initial position.
Since, final position =initial position, Displacement = 0, therefore, average velocity = 0
It can be concluded that average velocity is zero and average speed is greater than average velocity.
Answer: Option (B) is the correct answer.
When a person without any selfish motive does something for the benefit of others then it is known as altruism.
For example, a person organizes a food stall every weekend for the poor people of a village.
Therefore, we can conclude that an action that benefits others but not ourselves is an example of altruism.

Answer : The correct option is, (A) Meters per second squared
Acceleration : It is defined as the rate of change of velocity in unit time. It is a vector quantity. That means it is depend on the magnitude and the direction.
The S.I unit of of acceleration is, meter per second square
From the given options, option A is represent the unit of acceleration.
The option B represent the unit of energy.
The option C represent the unit of mass.
The option D represent the unit of force.
Hence, the correct option is, (A)
The answer is friction. The force acting upon the comparative motion of solid surfaces, liquid layers, and material elements sliding in contradiction of each other. When sides in contact move comparative to each other, the friction amid the two surfaces changes kinetic energy into thermal energy; in other words work to heat.
Friction. You will discern that natural fibers, wool, and cotton do not have static. All performed fibers comprise elements that when scraped together will have static electricity.would have believed that the stainless-steel drum and another metalwork of the dryer would remove the static charge to earth. Unless of course your machine is not earthed .
