The answer is refraction?

Ludmilka [50]4 years ago

The behavior of light makes it possible for you to see a spectrum of colors in a spray of water on a sunny day is refraction. The refractive index of a medium is dependent on the wavelength and hence light of different wavelength undergo refraction by different angle which causes the splitting of light beam in different color.

Since this is definitely a RIGHT triangle (the little square in the corner),
the hypotenuse is 15, 'h' is the side opposite the 38-degree angle, and

      sin(38°)  =  h / 15

Multiply each side by 15:     h = 15 sin(38°)

                                                =  15 (0.616)

                                             h  =    9.235

The fastest time ever run at Pikes Peak is 7:57. That’s way too long. If we removed all the curves, making a straight line from
anygoal [31]

Answer: 271.4 s

Explanation:

We are told the top speed (maximum speed) V_{max} the car has is:

V_{max}=203 mph=90.74 m/s taking into account 1 mile=1609.34 m

And the car's average acceleration a_{ave} is:

a_{ave}=0.091 g=2.93 ft/s^{2}=0.89 m/s^{2}

Since:

a_{ave}=\frac{V_{f}-V_{o}}{\Delta t} (1)

Where:

V_{f}=V_{max}=90.74 m/s is the car's final speed (top speed)

V_{o}=0 m/s because it starts from rest

\Delta t is the time it takes to reach the top speed

Finding this time:

\Delta t=\frac{V_{f}-V_{o}}{a_{ave}} (2)

\Delta t=\frac{90.74 m/s - 0 m/s}{0.89 m/s^{2}} (3)

\Delta t=t_{1}=101.95 s (4)

Now we have to find the distance d the car traveled at this maximum speed with the following equation:

V_{f}^{2}=V_{o}^{2} + 2a_{ave} d (5)

Isolating d:

d=\frac{V_{f}^{2}}{2a_{ave}} (6)

d=\frac{(90.74 m/s)^{2}}{2(0.89 m/s^{2})} (7)

d=4625.70 m (8)

On the other hand, we know the total distance D traveled by the car is:

D=12.42 miles = 19988.052 m

Hence the remaining distance is:

d_{remain}=D-d=19988.052 m - 4625.70 m (9)

d_{remain}=15362.35 m (10)

So, we can calculate the time t_{2} it took to this car to travel this remaining distance d_{remain} at its top speed V_{max}, with the following equation:

V_{max}=\frac{d_{remain}}{t_{2}} (11)

Isolating t_{2}:

t_{2}=\frac{d_{remain}}{V_{max}} (12)

t_{2}=\frac{15362.35 m}{90.74 m/s} (13)

t_{2}=169.45 s (14)

With this time t_{2} and the value of t_{1} calculated in (4) we can finally calculate the total time t_{TOTAL}:

t_{TOTAL}=t_{1}+ t_{2} (15)

t_{TOTAL}=101.95 s + 169.45 s (16)

t_{TOTAL}=271.4 s s

True or false the refraction of a wave is how many wavelengths pass a fixed point each second
Ksenya-84 [330]
False. That description fits the wave's 'frequency'. 
It has nothing to do with refraction.
