Answer:
well people find a hole on the ground and they can see water and that theu build the well around them but the answer is. C
Answer:
, it will sink
Explanation:
The density of an object is given by

where
m is the mass of the object
V is its volume
For the body in the problem, we have
m = 4 kg = 4000 g

Therefore, its density is

And the object will sink in water, because its density is larger than that of water, which is
. (an object sinks when its density is larger than that of water, otherwise it floats).
The sound absorption for wood is greater than the sound absorption coeffiecient for concrete at most frequencies, hence based on the coefficient of absorption for each material, wood is the best choice.
Answer:
Decreases ,,clockwise
Explanation:
When the switch is reopened then magnitude of magnetic flux through the loop will decreases and the direction of induced current will be clockwise (when seen from clockwise.
So the answer of the fill in the blank is decreases and clockwise.
Answer - B and B.
B) Decreases ,B)clockwise
