The dummy is moving with a speed 0 km/h relative to the seat in which it is sitting.
If the relative speed was non-zero, the dummy would move away from its seat, which contradicts the problem formulation.
Answer: Option (a) is the correct answer.
Explanation:
Ionic compounds are the compounds whose atoms are combined together by transfer of electrons.
An ionic compound has partial positive charge on the cation and partial negative charge on anion.
For example, NaCl is an ionic compound whose atoms are arranged orderly due to the opposite charges on its atoms.
So, an ionic compound forms a neutral compound but not a neutral element.
Thus, we can conclude that ionic compounds form crystal structures.
when a hole is made at the bottom of the container then water will flow out of it
The speed of ejected water can be calculated by help of Bernuolli's equation and Equation of continuity.
By Bernoulli's equation we can write
Now by equation of continuity
from above equation we can say that speed at the top layer is almost negligible.
now again by equation of continuity
here we have
now speed is given by
Kinetic Energy is movement energy (most simplistic way I can put it) so its motion.
