Answer:
Gs = 2.647
e = 0.7986
Explanation:
We know that moist unit weight of soil is given as
where, = moist unit weight of the soil
Gs = specific gravity of the soil
S = degree of saturation
e = void ratio
= unit weight of water = 9.81 kN/m3
From data given we know that:
At 50% saturation,
puttng all value to get Gs value;
Gs - 1.194*e = 1.694 .........(1)
for saturaion 75%, unit weight = 17.71 KN/m3
Gs - 1.055*e = 1.805 .........(2)
solving both equations (1) and (2), we obtained;
Gs = 2.647
e = 0.7986
Answer:
(b) BC → A
Explanation:
For given instance of S, certain dependencies (that is to say, A → B and B → C) can be said that they are not violated by this instance of S.
It can be said that an FD holds with respect to a relationship is to make a claim about all appropriate instances of S.
BC → A does not hold over S. To confirm, let's look at the tuples (1, 2, 3) and (4, 2, 3).
Hence, the answer is (b) BC → A.
Answer:
• Corona discharge means <u> </u><u>neutralization</u><u> </u><u>of</u><u> </u><u>charge</u><u> </u><u>action</u><u> </u><u>at</u><u> </u><u>a</u><u> </u><u>sharp</u><u> </u><u>point</u>
example; a pear shaped conductor, lightening conductor, van de graaf generator.
Explanation:
• In corona discharge, When a sharp conductor is placed somewhere in open space. The charges of opposite chrage attract the opposite ions in the air around that conductor.
• This increases the charge density and electric field intensity at the sharp point, this neutralises the charge at sharp point hence a discharge known as corona discharge occurs.
