Answer:

Velocity of wave = 2322 m /sec

Explanation:

We know that, Velocity of wave v = n λ

Given, n = 540 Hz, λ=4.3 m , v = ?

Putting the value of n and λ

Velocity of wave = 540 x 4.3 = 2322 m /sec

Answer:

V = 2322 M/s.

Explanation:

Wave velocity in common usage refers to speed, although, properly, velocity implies both speed and direction. The velocity of a wave is equal to the product of its wavelength and frequency (number of vibrations per second) and is independent of its intensity.

Wave speed is related to wavelength and wave frequency by the equation: Speed = Wavelength x Frequency. This equation can be used to calculate wave speed when wavelength and frequency are known.

For the calculation, use ( v= w × f) to figure out the velocity, there “w” is the wavelength, “f” is the frequency of the source, “c” is the constant speed of sound and “v” is the partcal velocity or waves velocity.

Lambda (uppercase/lowercase Λ λ), is the letter of the Greek alphabet, used to represent the "l" sound in Ancient and Modern Greek. In the system of Greek numerals, it has a value of 30. Letters that came from it include the Roman L and Cyrillic Л. It is used as shorthand as a symbol for wavelength.

- This is industry standard

V = f(λ)

V = 540(4.3)

V = 2322

14. The design for a rotating spacecraft below consists of two rings. The outer ring with a radius of 30 m holds the living quar

Zolol [24]

Answer:

$T= 11.0003$ s

Explanation:

From the question we are told that

The outer ring with a radius of 30 m

inner Gravity Approximately 9.80 m/s'

Outer Gravity Approximately 5.35 m/s.

Generally the equation for centripetal force is given mathematically as

Centripetal acceleration enables Rotation therefore?

$\omega ^2 r =Angular\ acc$

Considering the outer ring,

$\omega ^2 r = 9.8$

$\omega ^2= \frac{9.8}{30}$

$\omega = \sqrt{\frac{9.8}{30}}$

$\omega= 0.571 rad/s$

Therefore solving for Period T

Generally the equation for solving Period T is mathematically given as

$T= \frac{2\pi}{\omega}$

$T= \frac{2\pi}{0.571 rad/s}$

$T= 11.0003$ s

Groups of students are making measurements of small cars rolling across a table. the class has measuring tapes with markings in

TiliK225 [7]

To find the accurate measurement of small cars, the teacher asks students to make all the measurements in centimeters.

Centimeters Measurements:

A centimeter is a metric unit of measurement used for measuring the length of an object, It is written as cm
Centimeter is one hundredth of a meter, 1 meter is 0.01 cm.

Inches measurements:

An inch can be defined as a unit of length in the customary system of measurement. Length in inches is either represented by in or ''.
1 meter is equal to 39.37 inches

here, the cars are small objects.

The number of centimeters is always bigger,

because a centimeter unit is smaller than an inch unit, and it takes more of them when we are measuring.

Hence,

To find the accurate measurement of small cars, the teacher asks students to make all the measurements in centimeters.

The following best describes how an anthropogenic activity can increase ocean acidification?<br>

worty [1.4K]

Answer:

Emissions from power plants that burn fossil fuels increase atmospheric carbon dioxide, which is absorbed by the ocean.

Explanation:

Fossil fuels are burnt in power plants in order to produce energy. These fossil fuels contain carbon. Combustion of these fossil fuels emits oxides of carbon into the atmosphere. The oxides of carbon are carbon II oxide and carbon dioxide.

Carbon dioxide can be absorbed by the ocean to form carbonic acid according to the reaction equation;

CO2(aq) + H2O(l) ------> H2CO3(aq)

This is an anthropogenic activity which increases ocean acidification.

Boxes are transported from one location to another in a warehouse by means of a conveyor belt that moves with a constant speed o

krek1111 [17]

Answer:

P = 15.90 W

Explanation:

given,

speed of conveyor belt = 0.56 m/s

conveyor belt move up to = 2 m

angle made with the horizontal = 15°

mass of the box = 2.1 kg

rate is the force of the conveyor belt doing work on the box as the box moves up

P = F v cos ∅

P = 3 × 9.8 × 0.56 × cos 15°

P = 15.90 W
