In cloud formation, water vapor turns into water droplets which get bigger and bigger until it rains.

1 answer:

7 0

Basically there will be an increase in the air temperature in the clouds. Internally the water vapor is condensed in a cloud to fall like rain and release all the heat that it has inside. This heat is physically known as 'latent heat'. With this release of energy released as water vapor becomes drops of water, a microphysical process will be generated in the clouds that are responsible for controlling the conversion of water vapor into cloud particles and their respective rainfall.

The correct answer is A: Get Warmer.

A standing wave pattern is created on a string with mass density μ = 3.4 × 10-4 kg/m. A wave generator with frequency f = 61 Hz

uranmaximum [27]

Answer:

1) λ = 0.413 m , 2)v = 25,213 m / s , 3) T = 0.216 N , 4) m = 22.04 10-3 kg

Explanation:

1) The resonance occurs when the traveling wave bounces at the ends and the two waves are added, the ends as they are fixed have a node, the wavelength and the length of the string are related

λ = 2L / n n = 1, 2, 3 ...

In this case L = 0.62 m and n = 3

Let's calculate

λ = 2 0.62 / 3

λ = 0.413 m

2) the velocity related to wavelength and frequency

v = λ f

v = 0.413 61

v = 25,213 m / s

3) let's use the equation

v = √T /μ

T = v² μ

T = 25,213² 3.4 10⁻⁴

T = 0.216 N

4) the rope tension is proportional to the hanging weight

T-W = 0

T = W

W = m g

m = W / g

m = 0.216 / 9.8

m = 22.04 10-3 kg

5) n = 2

λ = 2 0.62 / 2

λ = 0.62 m

6) v = λ f

v = 0.62 61

v = 37.82 m / s

7) T = v² μ

T = 37.82² 3.4 10⁻⁴

T = 0.486 N

8) m = W / g

m = 0.486 / 9.8

m = 49.62 10⁻³ kg

9) n = 1

λ = 2 0.62

λ = 1.24 m

v = 1.24 61

v = 75.64 m / s

T = v² miu

T = 75.64² 3.4 10⁻⁴

T = 2.572 10⁻² N

m = 2.572 10⁻² / 9.8

m = 262.4 10⁻³ kg

A circular loop of flexible iron wire has an initial circumference of 167 cm, but its circumference is decreasing at a constant

Kisachek [45]

Answer:

Part a)

$EMF = 5.6 \times 10^{-3} V$

Part b)

Since the radius is decreasing so induced current will increase the flux through the coil

So it would be clockwise in direction

Explanation:

As we know that magnetic flux linked with the coil is given as

$\phi = \pi r^2 B$

now the rate of change in flux is given as

$\frac{d\phi}{dt} = 2\pi r \frac{dr}{dt} B$

now we know that circumference is decreasing at rate of 15 cm/s

so here we know the length of circumference as

$C = 2\pi r$

So rate of change in circumference is

$\frac{dC}{dt} = 2\pi \frac{dr}{dt}$

$\frac{1}{2\pi}(15 cm) = \frac{dr}{dt}$

final length of circumference at t = 8 s

$C = 167 - (15)(8) = 47$

Part a)

Now the induced EMF is given as

$EMF = (2\pi r)(\frac{1}{2\pi})(0.15)(0.5)$

$EMF = (0.47)(\frac{1}{2\pi})(0.15)(0.5)$

$EMF = 5.6 \times 10^{-3} V$

Part b)

Since the radius is decreasing so induced current will increase the flux through the coil

So it would be clockwise in direction

What is necessary for the production and transmission of sound?

Setler79 [48]

Vibration of a certain medium is necessary for the production of sound. For example vibratuon in the guitar's strings, vibration in vocal chord (when humans are speaking) etc etc.
Sound energy is the form of waves. Thus it requires a specific media to transmit itself. For instance sound travels fastest in solids. Sound also travels in liquids and air (gases). However, if there is no medium present. Sound will not travel.
Hope you get the answer :)
