Abar magnet moves through a loop of wire with constant velocity, and the north pole enters the loop first the induced current will be greatest when the magnet is located so that the loop is

Loop must be near the end of the pole of bar magnet

Explanation:

As we know by Faraday's law of electromagnetic induction the induced EMF or induced current in the loop is given by

here we know that

now we know that as the magnet comes closer to the loop the magnetic field due to any of the pole of magnet will increase.

So here the maximum flux will pass through the magnet when magnet is closer to the loop.

So here when A bar magnet moves through a loop of wire with constant velocity, and the north pole enters the loop first the induced current will be greatest when the magnet is located so that the loop is when Loop must be near the end of the pole of bar magnet

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .
