An unbanked (flat) curve of radius 150 m is rated for a maximum speed of 32.5 m/s. At what maximum speed, in m/s, should a flat

Rasek [7]

Answer:

The maximum speed is 21.39 m/s.

Explanation:

Given;

radius of the flat curve, r₁ = 150 m

maximum speed, $v_{max}$ = 32.5 m/s

The maximum acceleration on the unbanked curve is calculated as;

$a_c_{max} = \frac{V_{max}^2}{r} \\\\a_c_{max} = \frac{32.5^2}{150} \\\\a_c_{max} = 7.04 \ m/s^2$

the radius of the second flat curve, r₂ = 65.0 m

the maximum speed this unbanked curve should be rated is calculated as;

$a_c_{max} = \frac{V_{max}^2}{r_2} \\\\V_{max}^2 = a_c_{max} \ \times \ r_2\\\\V_{max} = \sqrt{a_c_{max} \ \times \ r_2} \\\\V_{max} =\sqrt{7.04 \ \times \ 65} \\\\V_{max} = 21.39 \ m/s$

Therefore, the maximum speed is 21.39 m/s.

Which medium caused the most bending of light as it passed through?

babunello [35]

I wasn't there observing the experiment while you and your class
performed it, so I don't really know how it was set up, or what
happened.

But I can tell you this: Light doesn't bend while passing through
any medium. It only bends at the boundary where one medium
meets a different one.

Which properties can be used to determine whether a substance is a liquid or a plasma? Check all that apply.

Annette [7]

A liquid is a phase of a substance that is characterized by being flowing and has no shape. The molecules of this substance are far apart but much closer than the particles in a gas. Plasma is a state of a substance that consists of ionized gas. So, it in the phase of a gas and has a charge. We can therefore distinguish the two by checking which substance has a charge.
