Carmen runs each lap in 4 minutes. She will run less than 28 minutes today. What are the possible numbers of laps she will run t
drek231 [11]

Answer:

# of laps < 28, the number of laps will be less than 28.

1 lap = 4 minutes

28 laps = 112 minutes

Because we want less than 28 laps,

27 laps = 108 minutes

She can run any amount of laps less than 28.

Find (a) the amplitude, (b) the wavelength, (c) the period, and (d) the speed of a wave whose displacement is given by y= 1.5 co
leonid [27]

Answer with Step-by-step explanation:

We are given that displacement of wave

y=1.5cos(0.68x+37t)

Where y in cm  and t in sec.

a.Compare it with

y=Acos(kx+\omega t)

Amplitude of wave=A

We get A=1.5

Amplitude=A=1.5  cm

b.k=0.68

\frac{2\pi}{\lambda}=0.68

\lambda=\frac{2\times 3.14}{0.68}=9.2 cm

Using \pi=3.14

Wavelength of the wave=9.2 cm

c.Period=\frac{2\pi}{T}=\omega

\frac{2\pi}{T}=37

T=\frac{2\times 3.14}{37}=0.17 s

The period of the wave=0.17 s

Speed of the wave=\nu \lambda=\frac{\lambda}{T}=\frac{9.2}{0.17}

Speed of the wave=54.1 cm/s
