Answer:
Sound waves are longitudinal in nature.
Explanation:
There are many types of waves like transverse, longitudinal, electromagnetic wave etc.
Sound waves are longitudinal in nature. In longitudinal type of wave, the medium particles moves parallel to the propagation of the wave. This type of waves move in the form of compression and rarefaction.
In compression, the particle density at a point is very less while in rarefaction, the particle density at a point is very high.
So, the correct option is (b) "longitudinal wave".
Answer:
Scientific Definition of Mass Mass is the quantity of inertia (resistance to acceleration) possessed by an object or the proportion between force and acceleration referred to in Newton's Second Law of Motion (force equals mass times acceleration).

Explanation:
Scientific use: The Einstein's THEORY of relativity states that "Time Is Absolute".
Everyday use: Einstein's LAW of relativity says that time is not the same at all places and events.
Answer:
W = -2080 J
Explanation:
initial position vector of the object is given as

similarly final position vector is given as

now the displacement of the object is given as

now we will have


now the force on the object is given as

so here in order to find the work done
