Answer:
c) depends only on the type of fluid
Explanation:
The pressure of a fluid at a specific depth is given by:
where
is the density of the fluid
g is the gravitational acceleration
h is the depth
We see that for a given depth h, the pressure of the fluid depends only on its density, so only on the type of fluid. Therefore, the correct choice is
a) depends only on the type of fluid
The other choices are wrong because:
b) the pressure is exerted in every direction
c) the pressure does not depend on the total volume of the fluid, but only on the depth h
If one reverse the orientation of a permanent magnet ITS MAGNETIZATION WILL BE PERMANENTLY REVERSED. This is because, the magnetic domains inside the permanent magnet aligned with the new applied field and increase with it while those domains that are anti aligned with that field will shrink.

Answer:
3.974 Joule
Explanation:
Diameter of ring = 7.7 cm
a = Distance from the center = d/2 = 3.85 cm = 0.0385 m
Q = Charge = 5 mC
q = Charge to move = 3.4 mC
k = Coulomb constant = 9×10⁹ Nm²/C²
Work done will be equal to Potential energy when mass is at center

∴ Work to move a tiny 3.4 mC charge from very far away to the center of the ring is 3.974 Joule
Answer:
Wc = 7.84 weight of crown
Ww = 7.84 - 6.86 = .98 weight of water displaced
Density = 7.84 / .98 = 8 crown is 8 X that of water
Since gold has a density of 19.3 that of water the crown is certainly not 100 percent (if any) gold
