The wavelength is 2m.

Hence, Option c) 2m is the correct answer

Given that;

Frequency; [tex]f = 30Hz[/tex]

Speed; [tex]v = 60m/s[/tex]

Wavelength; [tex]\lambda =\ ?[/tex]

using the expression for the relations between wavelength, frequency and speed of wave:

[tex]\lambda = \frac{v}{f}[/tex]

Where [tex]\lambda[/tex] is wavelength, f is frequency and v is speed.

We substitute our given values into the equation

[tex]\lambda = \frac{60m/s}{30Hz}\\\\\lambda = \frac{60m/s}{30s^{-1}}\\\\\lambda = 2m[/tex]

The wavelength is 2m.

Hence, Option c) 2m is the correct answer.

The frequency of the moving wave is 30 Hz and if it is moving at the speed of 60 m/s then the wavelength will be equal to 2 m.

The distance between two identical locations (adjacent crests) in successive cycles is known as the wavelength, and it is used to describe waveform signals that are transmitted over wires or into space. Typically, in wireless systems, this length is specified in meters (m), centimeters (cm), or millimeters (mm).

The wavelength is more frequently described in nanometers (nm), which are units of 10⁻⁹ m, or angstroms, which are units of 10⁻¹⁰ m, for infrared (IR), visible light (UV), and gamma radiation.

As per the provided given data in the question,

Frequency, f = 30 Hz

Speed, v = 60 m/s

Then, the wavelength of the moving wave will be,

λ = v/f

= 60/30

λ = 2 meters.

Therefore, the wavelength will be 2 meters.

Explanation:

When water vapor in the air comes into contact with something cool, like the ceiling of a tent, its molecules slow down and get closer together. When that happens, the gaseous water vapor turns back into liquid water droplets. That's condensation!

Answer:

D.

Explanation:

it is indeed a representation of how the valence electrons in an element,coumpound, or ion are arranged.

to ensure you i was just quized on this and D is the correct anwser

A representation of the arrangement of valence electrons in an element, compound, or ion -  statement most completely describes a Lewis electron dot diagram. Hence, option (D) is correct.

If the compound's molecular formula is known, electron dot structures or Lewis dot formulas can be drawn.

It describes the type of bond and the placement of the atoms within the molecule that are joined together. In honor of American chemist Gilbert Newton Lewis, molecules are depicted as having a Lewis electron dot structure or simply a Lewis structure.

Lewis dot structures, also known as electron dot structures, are schematics that show the interatomic chemical bonds in a molecule. Additionally, they show how many lone pairs there are overall in each of the atoms that make up the molecule. Common names for Lewis dot structures include electron dot structures and Lewis structures. Lewis described an acid as an electron pair acceptor, while a base is an electron pair giver.

If you are saying How much does the tilt of the Earth affect the climate

This varies between a tilt of 22.1 and 24.5 degrees over a period of about 41,000 years. This trend not only affects the average temperature of the earth, but also how prominent the seasons are. Procession is a wobble in the earth's axis.

Answer:

The tilt of the Earth causes some places to be hit more by the sun's rays, while the topography affects wind travel.

Explanation:

Because of the way the Earth is tilted on its axis, some parts receive more heat due to being hit more directly by the sun's rays. This is the reason why the North pole is very cold since it doesn't get directly hit by the sun's rays. As for the topography, the way the wind travels is affected by mountains, and the temperature of winds are affected by the places the wind originated from. Also, high altitude places such as mountain summits are colder, while low altitude places are warmer. So, when an area is under direct sunlight, it causes warm climate, and when an area receives warm air because of its topography, it causes further heat.

Answer:

Net force = 0

Explanation:

Whenever there is an unbalanced force, it shows that the net force doesn’t = 0 because if net force = 0, then everything force is balanced by another force. If there is an unbalanced force, acceleration will occur in the direction the net force is towards.

Answer:

0.9m/s^2 (yours is 0.87, so choose that)

Explanation:

formula for centripetal acceleration:

v^2/r

to find v, we know that f=1/90s, and r=180m.

v=(2pir)/T

v=(2pi(180))/90

v=12.6m/s

now plug into a=v^2/r

a=(12.6)^2/180

a=0.9m/s^2
