41. Electric and magnetic forces can both make certain objects move. For example, a positively charged particle will repel anoth
notsponge [240]

Answer:

Place the north pole of a magnet next to the north pole of another magnet.

Explanation:

Looking at the comments, we can see that the options are:

Place the south pole of a magnet next to the north pole of another magnet.

Place the north pole of a magnet next to the north pole of another magnet.

First, we know that a positively charged particle will repel another positively charged particle.

The same thing happens for magnetic forces (usually we define a magnetic flow from the south pole to the north pole, so we can define the south pole as the "positive" and the north pole as the "negative", but this is only notation and do not really matter), a south pole of a magnet will repel another south pole of a magnet (and the same happens for the north poles)

Then the correct option is:

Place the north pole of a magnet next to the north pole of another magnet.

A roller-coaster car has a mass of 1040 kg when fully loaded with passengers. As the car passes over the top of a circular hill
rusak2 [61]

Answer:

a.6373.5 N

b.-3837.6 N

Explanation:

Mass of roller coaster=m=1040 kg

Radius=r=24 ,

a.v=9.4m/s

Normal force=F_N

According to question

mg-F_N=\frac{mv^2}{r}

Where g=9.81 m/s^2

Substitute the values

1040\times 9.81-F_N=\frac{1040\times (9.4)^2}{24}

10202.4-F_N=3828.9

F_N=10202.4-3828.9=6373.5 N

b.v=18m/s

g=9.81 m/s^2

1040\times 9.81-F_N=\frac{1040\times (18)^2}{24}

10202.4-F_N=14040

F_N=10202.4-14040=-3837.6 N
