A 600-kg car traveling at 30.0 m/s is going around a curve having a radius of 120 m that is banked at an angle of 25.0°. The coefficient of static friction between the car's tires and the road is 0.300. What is the magnitude of the force exerted by friction on the car?

Explanation:

Here the total force at the horizontal components will be equal to the centripetal force on the car. So we will have:

(1)

Now, the sum of forces at the vertical direction is equal to 0.

(2)          

Let's combine (1) and (2) to find f(fr)

I hope it helps you!

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.
