Acar weighing 10.1 kn and traveling at 11.5 m/s without negative lift attempts to round an unbanked curve with a radius of 65.0 m. (a) what magnitude of the frictional force on the tires is required to keep the car on its circular path?

a) 2095N

Explanation:

M = w/g = 10100/9.8 = 1.03 x 10^3 kg

Normal force = Gravitational force

Fn = M x g

Friction is

f = m x v^2 / r = 1.03 x 10^3 x (11.5)^2 / 65

F = 2.10 x 10^3 N

N/b to calculate maximum friction force,

Fmax = Us x mg

Fmax = Us x 10100N

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

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.
