A car of mass M = 1000 kg traveling at 50.0 km/hour enters a banked turn covered with ice. The road is banked at an angle θ , an

kupik [55]

The radius of the curved road at the given condition is 54.1 m.

The given parameters:

<em>mass of the car, m = 1000 kg</em>
<em>speed of the car, v = 50 km/h = 13.89 m/s</em>
<em>banking angle, θ = 20⁰</em>

The normal force on the car due to banking curve is calculated as follows;

$Fcos(\theta) = mg$

The horizontal force on the car due to the banking curve is calculated as follows;

$Fsin(\theta) = \frac{mv^2}{r}$

<em>Divide </em><em>the second equation by the first;</em>

$\frac{Fsin(\theta)}{Fcos(\theta) } = \frac{mv^2}{rmg} \\\\tan(\theta) = \frac{v^2}{rg} \\\\r = \frac{v^2}{g \times tan(\theta)} \\\\r = \frac{13.89^2}{9.8 \times tan(20)} \\\\r = 54.1 \ m$

Thus, the radius of the curved road at the given condition is 54.1 m.

How does the north pole of a magnet respond to the poles of other magnets?

tensa zangetsu [6.8K]

Answer:

Explanation:

A magnet has a magnetic field around it which originates at the north pole and enters through the south pole.

In a magnet, like poles will repel each other and unlike poles will attract.

The north pole of one magnet will repel another north pole of another magnet.
North pole of one magnet will attract the south pole of another magnet.
This is the law of attraction and repulsion of magnet.
