Answer: Option (A) is the correct answer.
Explanation:
When more and more energy is provided to a gas then its atoms move more rapidly.
This rapid and continuous movement converts the gas into hot ionized ions which have positively charged ions and negatively charged electrons.
Therefore, we can conclude that as the atoms move faster, the gas can change into a plasma.

Hey buddy, here is your answer. Hope it helps you.
Explanation:
Yes, weight of a body is not constant, it varies with the value of acceleration due to gravity, g. Weight of a body is zero, when it is taken to the centre of the earth or in the interplanetary space, where g=0. Mass is the total matter in a body, while weight is the force by which the body is attracted.
Weight is never constant while mass is. So we can have weight zero but with some mass. This will happen when an object is at the centre of earth, as g=0 at centre of earth , so weight will be 0 while mass will always be constant everywhere
Explanation:
Given that,
Fencing to be done, P = 400 m
Area of the rectangular garden, 
Let l is the length and b is the breadth of the garden. The area of the rectangle is given by :
............(1)
The perimeter of the garden is given by :
...............(2)
On solving equation (1) and (2), we get the value of l and b are as follows :
l = 90 m and b = 110 m
or
b = 90 m and l = 110 m
So, the dimension of the garden is 90 m by 110 m. Hence, this is the required solution.
Velocity is a derived quantity, which is derived from two fundamental quantities ilength ( displacement ) and time
it can be depicted as :
