In lab, your instructor generates a standing wave using a thin string of length L = 1.65 m fixed at both ends. You are told that

the standing wave is produced by the superposition of traveling and reflected waves, where the incident traveling waves propagate in the +x direction with an amplitude A = 3.65 mm and a speed vx = 13.5 m/s . The first antinode of the standing wave is a distance of x = 27.5 cm from the left end of the string, while a light bead is placed a distance of 13.8 cm to the right of the first antinode. What is the maximum transverse speed vy of the bead?

Answer:

The maximum transverse speed of the bead is 0.4 m/s

Explanation:

As we know that the Amplitude of the travelling wave is

A = 3.65 mm

Now the speed of the travelling wave is

v_x = 13.5 m/s

now we know that distance of first antinode from one end is 27.5 cm

so length of the loop of the standing wave is given as

\frac{\lambda}{4} = 27.5 cm

\lambda = 110 cm

now we have

N = \frac{2L}{\lambda}

N = \frac{2(1.65)}{1.10}

N = 3

now we have

R = 2A sin(kx)

R = 2(3.65) sin(\frac{2\pi}{1.10}x)

R = 7.3 sin(1.82 \pi x)

now at x = 13.8 cm

R = 7.3 sin(1.82 \pi (0.138))

R = 5.18 mm

now we have

f = \frac{v}{\lambda}

f = \frac{13.5}{1.1}

f = 12.27 Hz

now maximum speed is given as

v_y = R\omega

v_y = (5.18 \times 10^{-3})(2\pi(12.27))

v_y = 0.4 m/s

A granite monument has a volume of 25,365.4 cm3. The density of granite is 2.7 g/cm3. Use this information to calculate the mass
LiRa [457]
As density = mass/volume

So

Mass = density *volume

Mass = 25,365.4 * 2.7 = 68,486.58 g

<span>Mass of the granite monument to the nearest tenth = 68,485.6 g</span>

During metamorphism, what is the major effect of chemically active fluids?
xz_007 [3.2K]

Answer:

Option b

Explanation:

Metamorphism is the process where the variation of the geological texture resulting from the different arrangement of the minerals or the variation of minerals in protoliths, i.e., pre- existing rocks take place such that there occurs no change in state of the protolith, i.e., it does not melt into magma.

The change takes place as a result of the presence of chemically active fluids, heat and pressure.

There is a reaction between the chemically active fluid and the rock through which it passes and promotes the movement of the dissolved ions of silicate and promotes the growth of the mineral grains.

The rotational speeds of four generators are listed in RPM (revolutions per minute). Arrange the generators in order based on th
artcher [175]

with the same generator, so the only factor for producing the slectric field is only the speed. The faster the rotational speed of the generator the greater it produce electric field. So the sequence is 3000 rpm < 3200 rpm < 3400 rpm < 3600 rpm

It takes a slug 20 minutes to travel from the grass to the trash can , a trip of 15 meters. How far could the slug travel in 60
inn [45]

Answer:

45 meters

Explanation:

20 min = 15 meters

So if 20 x 3 = 60

you have to do 3 x 15 !

- which equals to 45 <3

Consider a force of 750 n (roughly the weight of an adult human). over what area (in cm2) would this force need to be applied in
polet [3.4K]
p = \frac{f}{a}
P=25x10^6 andF=750.So plug in everything to solve for A. which is 3x10^-5m^2 OR 0.3mm^2
