Answer:
a region around a magnet in which you can measure magnetic forces.
Explanation:
Magnetic field is the field that surrounds the magnet so that when a magnetic material is placed in that region then that magnetic material will experience some magnetic force on it
this magnetic force is given by
here we know that
m = magnetic pole strength
B = magnetic field strength
so correct answer will be
a region around a magnet in which you can measure magnetic forces.

The density of seawater at a depth where the pressure is 500 atm is
Explanation:
The relationship between bulk modulus and pressure is the following:
where
B is the bulk modulus
is the density at surface
is the variation of pressure
is the variation of density
In this problem, we have:
is the bulk modulus
is the change in pressure with respect to the surface (the pressure at the surface is 1 atm)
Therefore, we can find the density of the water where the pressure is 500 atm as follows:
