A meandering stream has a single channel that winds snakelike through its valley, so that the distance 'as the stream flows' is greater than 'as the crow flies. ' As water flows around these curves, the outer edge of water is moving faster than the inner.

What is the relation between Physical states of solution and solvent
posledela

Explanation:

The solute does not have to be in the same physical state as the solvent, but the physical state of the solvent usually determines the state of the solution. As long as the solute and solvent combine to give a homogeneous solution, the solute is said to be soluble in the solvent.

You are given a sample of metal and asked to determine its specific heat. You weight the sample and find that its weight is 28.4
lidiya [134]

Answer:

The samples specific heat is 14.8 J/kg.K

Explanation:

Given that,

Weight = 28.4 N

Suppose, heat energy E=1.25\times10^{4}\ J

Temperature = 18°C

We need to calculate the samples specific heat

Using formula of specific heat

Q=mc\Delta T

c=\dfrac{Q}{m\Delta T}

Where, m = mass

c = specific heat

\Delta T = temperature

Q = heat

Put the value into the formula

c=\dfrac{1.25\times10^{4}}{\dfrac{28.4}{9.8}\times(18+273)}

c=14.8\ J/kg. K

Hence, The samples specific heat is 14.8 J/kg.K

The particles of a gas are actually _____. electrons or protons protons or neutrons atoms or elements atoms or molecules
miskamm [114]

<u>Answer</u>

atoms or molecules

<u>Explanation</u>

A pure gas such as argon or neon is made up of individual atoms. Other compound gasses such as oxygen or carbon dioxide are made up of elements.

Protons, neutrons and electrons are parts of an atom. They are not actually particles but charges.

The answer to the question is <em>atoms or molecules.</em>

A swimming duck paddles the water with its feet once per time interval of 1.6 s, producing surface waves with this period. The d
soldier1979 [14.2K]

Answer:

a. 0.275m/s

b. 1.08m

Explanation:

Since the duck the paddle the water at an interval of 1.6sec, we can determine the frequency of the wave formed using the equation

f=1/T

Where T is the period.

f=1/1.6

f=0.625Hz.

Also from the equation used in determining the speed of a wave

V=fλ,

v=0.625*0.2

v=0.125m/s

in the question it was stated that that the duck produce a wave moving at a speed of 0.40m/s.

Hence the speed of the duck is

v(duck)=0.40-0.125

v(duck)=0.275m/s

b. The distance between the crest behind the duck is the wavelength of the waves.

To determine this, the wavelength is expressed as

λ=v/f

but the speed in this case is the speed of the duck and the surface wave,as this account for the wave speed behind the duck,

Hence we have

λ=(0.40+0.275)/0.625

λ=1.08m.

The wavelength behind the duck is 1.08m
