Ans: C) Solid
Explanation: We will look into different states
A) Liquid : In liquid state molecules are not very tightly bound to each other. So, they have no fixed shape . They take the shape of container in which they are kept.
B) Gas : In gaseous state molecules are very loosely bound so they have very less intermolecular forces so they have much more freedom of movement.So, it will be also not correct.
D) Plasma : In Plasma state approximately equal amount of positive or negative charges are there, although its a type of hot ionized gaseous state but but due its different properties then other gases it is considered the 'fourth' state. And it also can't maintain it's definite shape and volume.So we will eliminate that also.
C) Solid : Finally we are left with solid state. Here molecules are tightly bound to each other . So, it doesn't change its shape and volume when kept in different container.
So 'Solid' state is the correct choice.
Hope it helps!!!
Answer:
I dont think the universe has a center because there is such a vast majority of stars, planets, and galaxys that havent even been discovered that space could be endless. so no i dont think there is a center to the universe.
Explanation:
Answer: r^-1
Explanation:
V = (k × Q) / r, where V is electric potential, k is constant and r is distance from charge.
Since Q will not change, it can be considered a constant too.
So, we can write V ∝ 1/r
which is same as V ∝ r^-1
Answer:
Explanation:
From the question we are told that
The wavelength is 
The length of the of the plate is 
The radius of the wire is 
Generally the diameter of the wire which is the distance between the glass plates is mathematically represented as
=> 
=> 
Generally the condition for constructive interference is mathematically represented as
=> 
=> 
=>
The ball is using an reaction and opposite reaction, so when you dribble a basketball you push the ball with downward force and the ground pushes the ball back up thus making the opposite reaction.
