Answer: D
Key thing to keep note, is "refraction"...
Look at some experiments on YouTube, it's helps me a lot.
Answer:
Privity of contract, Assignment
Explanation:
Privity of contract is the relationship that exist between the parties to a contract which allows them to sue each other meanwhile it prevents a third party from doing so. It is a common law principle which provides that a contract cannot confer rights or impose obligations upon any person who is not a part to the contract.
<u>Assignment:</u> This is the act of transferring all or part of one's rights arising under a contract to another another person.
Complete Question
An infinite sheet carries a uniform, positive charge per unit area. The electric field produced by the sheet is represented by parallel lines drawn with a density N lines per m2 that are perpendicular to and away from the sheet. The charge per unit area on the sheet is doubled. How should the density of the electric field lines be changed?
A It should stay the same
B It should be quadrupled.
C It should be quintupled
D It should be doubled.
E It should be tripled
Answer:
Option D is the correct option
Explanation:
Generally electric field is mathematically represented as
Where 
is the charge per unit area (Charge density )
From the question we are told that is doubled hence the
Looking the equation above we see that the value of the electric field will also double given that it is directly proportional to the charge density
Hence, 0.60+2.25eV is the solution to this problem
Answer:
a. arranging from least to higher pressure exerted by object B ,D A, C
b object B exert maximum pressure on surface because pressure is indirectly proportional to the surface area from the above figure we can easily conclude that object a have least surface area so, it exert more pressure on surface.
c.object C exert minimum pressure on surface because pressure is indirectly proportional to the surface area from the above figure we can easily conclude that object a have large surface area so, it exert less pressure on surface.
