Abar magnet is placed on a table so that the north pole faces right.

which statement describes the magnetic field lines 2 cm above the table?

they are pointing down into the table.
they are pointing right to left.
they are pointing left to right.
they are pointing up out of the table.

The correct answer is C. They are pointing right to left.

Explanation.

A magnet has two poles, a north pole and a south pole.  When dealing with magnets, we define the concept of a magnetic field. A magnetic field represents the effect of the magnet on magnetic materials and moving charges in the space around the magnet. For every magnet, the magnetic field lines always point away from the north pole of the magnet towards the south pole. Since the north pole of this magnet faces right, the magnetic field lines point towards the left.

The correct answer is C. They are pointing right to left.

c)as speed changes, wavelength and frequency change.

everything changes!

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
