Explanation:
Both Distance and displacement deals the distance of the object but they differ distinct is scalr quantity and displacement is vector quantity or have Direction
Answer:
The closer two charged objects are the stronger the electrical force between them.
Like charges repel and opposite charges attract.
The further away two charged objects are the weaker the electrical force between them.
Explanation:
Coulomb's law tells us about the electric force/electrostatic force/Coulomb force between two charged particles. The force (F) between the particles Q and q, separated by a distance r is given as,
where k = Coulomb constant.
It is evident from the equation that closer the charged particle force will be more. As the distance between the charge increases the force will be weaker. Also the like charges will repel and opposite charges will attract.
I would say B. A stable home and varied activities
Answer:
Answer
Advantages of alcohol over Mercury
(a) Freezing point of alcohol is −117∘
C and hence can record very low temperature For example in Arctic and Antarctic regions temperature may fall below −80∘
C which cannot be measured by mercury thermometer because mercury freezes at−39 ∘ C
(b) The expansion of alcohol per degree rise in temperature is much more around six times more then that of mercury and hence is more sensitive
(c) it can be coloured brightly by adding some dye in it and hence is easily detectable
