miss Akunina [59]

Answer:

The number of turns in the second coil is more than the coil 1.

Explanation:

The magnetic field lines are the imaginary path on which an isolated north pole moves if it is free to do so.

The tangent at any point to the magnetic field line, gives the direction of magnetic field at that point.

More be the crowd ness of magnetic field lines more is the strength of magnetic field.

Here the crowd ness of magnetic field lines is more in figure 2 , so the magnetic filed in figure 2 is more than 1. It shows that the number of turns in the second coil is more than the 1 and also the current in the coil 2 is more than 1 .

An arrow is shot at an initial velocity of 224 ft/sec from a height of 44 feet, ay what time will the arrow be 824 feet above th

Bingel [31]

The arrow is subject to the constant downward pull of gravity, so its vertical position over time is given by

$y=44\,\mathrm{ft}+\left(224\,\dfrac{\mathrm{ft}}{\mathrm s}\right)t+\dfrac12\left(-32.1\,\dfrac{\mathrm{ft}}{\mathrm s^2}\right)t^2$

We want to find $t$ for which $y=824\,\mathrm{ft}$ . You should find two solutions at $t=6.67\,\mathrm s$ and $t=7.29\,\mathrm s$ .
