A certain AM radio wave has a frequency of 1.12 x 106 Hz. Given that radio waves travel at 2.99 x 108 m/s, what is the wavelength of this radio wave? (Round your answer to three significant figures.) Answer in "m" units
Answer:
2.67×10² m
Explanation:
Applying
V = λf............... Equation 1
Where V = Velocity of radio wave, λ = wave length, f = frequency.
make λ the subject of the equation
λ = V/f................ Equation 2
From the question,
Given: V = 2.99×10⁸ m/s, f = 1.12×10⁶ Hz.
Substitute these values into equation 2
λ = (2.99×10⁸)/(1.12×10⁶)
λ = 2.66696×10² m
λ ≈ 2.67×10² m

which type of motion occur in a lift in one word
Pls answer
Answer:
Explanation:
Lift occurs when a moving flow of gas is turned by a solid object. The flow is turned in one direction, and the lift is generated in the opposite direction, according to Newton's Third Law of action and reaction. Because air is a gas and the molecules are free to move about, any solid surface can deflect a flow.
A force is acting on a 3-kg object during 5 seconds. If the object initially has a speed of 1.5m/s and after applying the force its speed is 4 m/s
Answer:
1.5 N
Explanation:
You've left us to guess what the question is. I will Assume it is what's the force?
Givens
m = 3 kg
vi = 1.5 m/s
vf = 4 m/s
t = 5 seconds
Formula
F = m * (vf - vi)/t
Solution
F = 3 * (4 - 1.5) / 5
F = 1.5 N

Answer:
At infinity the image is formed
When a lens produces light rays that are parallel, the image is: C. non-existent.
A ray diagram can be defined as the graphical representation of the possible paths light takes from one point (source) to another.
Hence, a ray diagram is a graphical representation of how light interacts with a boundary, so as to help us view a point on the image of an object.
Basically, the characteristics of an image produced from a lens or mirror can be determined by drawing a ray diagram of the possible paths taken by light.
On a ray diagram, an image produced from a lens is non-existent when the lens produces light rays that are parallel because the refracted rays of light neither diverge nor converge.
In conclusion, an image cannot be formed (non-existent) when a lens produces light rays that are parallel, due to refraction.

what effect does the earth's surface have on solar radiation?
A. The ground absorbs half the solar radiation and stored it as infrared radiation for centuries
B. Half of the solar radiation is absorbed and converted to infrared (heat)
C. Nearly all solar radiation is reflected back into space by the ground
Answer:
B.
Explanation:
Solar radiation that is not absorbed or reflected by the atmosphere (for example by clouds) reaches the surface of the Earth. The Earth absorbs most of the energy reaching its surface, a small fraction is reflected. In total approximately 70% of incoming radiation is absorbed by the atmosphere and the Earth’s surface while around 30% is reflected back to space and does not heat the surface. The Earth radiates energy at wavelengths much longer than the Sun because it is colder. Part of this longwave radiation is absorbed by greenhouse gases which then radiate energy into all directions, including downwards and thereby trapping heat in the atmosphere.
Hope this helps, sorry if it is incorrect. Have a great day/night!

A fisherman sees 7 wave crests go by in 10.0 s. The crests are 2.43 m apart. Find the period of the wave. (Unit = s)
Velocity of the wave is 1.7 m/s
Explanation:
As we know that the frequency of the wave is defined as the number of waves crossing a fixed point per second
So here we will have
Also we know that the distance between two consecutive crest or two consecutive trough is known as wavelength
So here the wavelength of the wave is given as
now we have
The wave period will be 1.42 s.
What is wave period?The time interval, expressed in seconds, separating two waves as they pass throughout a stationary point has been known as the wave period.
What is wave?A pulse seems to be a single disturbance, whereas a wave would be a persistent, repeated interruption of a medium.
Calculation of wave period
The frequency = 7 / 10 = 0.7 Hz
Wave period can be calculated by the formula:
Wave period = 1 / frequency
Put the value of frequency in above equation.
Wave period = 1 / 0.7
Wave period = 1.42 s
Therefore, the wave period will be 1.42 s
