Answer:
502.51 kg/m^3
Explanation:
Upthrust on object in water is 40 - 20 = 20 N
Upthrust is equal to the buoyancy forces given as
B = pgv
p is density of water 1000 kg/m^3
g = acceleration due to gravity 9.81 m/s^2
v is the volume of liquid displaced.
Therefore
B = 1000 x 9.81 x v
20 = 9810v
v = 2.038x10^-3 m^3
For Upthrust in unknown liquid, we have 40 - 30 = 10 N
Bouyancy force for the liquid will be
B = P x 9.81 x 2.038x10^-3
NB- the same volume of fluid will be displaced i.e 2.038x10^-3 m^3
Equating we have
10 = P x 9.81 x 2.038x10^-3
10 = 0.0199p
p = 10/0.0199 = 502.51 kg/m^3
Answer:
Option D is correct
Explanation:
There is no well substantiated explanation of the theory which has been confirmed by series of standard experiment and observation.
The ship leaving from the Greece will reach the Kuwait city by reaching the Medittareean sea, then going to Suez Canal. Afterward, the ship should move towards the Red Sea. From the red sea, it should go to the Arabain Sea, which will let it enter the Persian Gulf.
These appearances are communicated through families, most of
the time finished stories passed down from one generation to the next. This permits
for the culture and the principles/norms for the civilization to bear. These
stories permit for the philosophy to grip a common sense of individuality, particularly
in civilizations that have strong family bonds.
