Answer:
4
Explanation:
4. speed, because there is a mention of time
Speed v/s Velocity:Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement. Velocity is speed with a direction. For example: The Dog runs at 9 km/h (kilometers per hour) is a speed. But saying he runs 9 km/h Westwards is a velocity.Thus, the correct option is 4 since no direction is given so it cannot be velocity.

someone made a copy of an analog wave in a digital wave compare the copies with the original waves and explain which type of waves more reliable way to encode code to transmit information
Answer:
Digital waves are more reliable due to the fact that most modern-day tech, such as phones and computers use digital codes such as numbers and graphs, in that case using digital code would be a lot easier to use.
Hope this is helped :)
The digital wave is more reliable to encode and transmit information.
If we carefully analyze the image provided here, we can clearly see some differences in both the waves.
One side of the image represents the original analog wave and the copied analog wave. While the other side of the image represents the original digital wave and the copied digital wave.The copy of the analog wave looks distorted, because the analog wave picks up noise which are high frequency unwanted signals produced by circuits, whereas the copy of the digital wave is free of distortion. Here the digital wave has an advantage over analog wave.Since the digital wave is less prone to be affected by noise, there is relatively nominal data or information loss. They are also easy to separate from other digital signals. Their encoding and decoding is easier than analog waves.Hence the above factors make the digital signals or waves more reliable than analog waves.

Which statement describes how globes represent Earth’s surface?
O They model all of Earth’s surface.
O They are flat and two dimensional.
O They represent underwater features using symbols.
O They provide detailed information about towns or cities.
"They model all of Earth’s surface" This statement describes how globes represent Earth’s surface. The correct option is A.
What is a globe?A globe is a three-dimensional(3D) representation of the Earth's surface.
It is a spherical model that accurately depicts the Earth's shape, size, and features, including continents, oceans, mountains, and other physical features.
Globes are often used as educational tools to teach geography, navigation, and other related subjects. They are useful for understanding the relationship between different parts of the world and visualizing the Earth. Unlike flat maps, globes do not distort the size or shape of land masses, and they accurately represent the distances between different locations.
The Earth's globe is also a three-dimensional(3D) representation of the Earth's surface that accurately Shows the Earth's actual dimensions, and continents, oceans, mountains, and other physical features.
The Earth's globe is a sphere, or a ball, with a diameter of approximately 12,742 kilometers (7,918 miles).
It is the only planet in our solar system known to support life, and it is home to a vast array of diverse ecosystems and species.
Here in the question,
The statement that describes how globes represent Earth's surface is: "They model all of Earth's surface." Globes are three-dimensional models of the Earth that show the planet's entire surface. Unlike maps, globes represent the Earth's surface accurately in terms of shape, distance, and direction.
Note: They do not use symbols to represent underwater features or provide detailed information about towns or cities.
Therefore, The globe represents the model of all of the earth's surface.

Explain the relationship between wavelength and frequency in the electromagnetic spectrum.
Answer:
The wavelength and frequency of light are closely related. The higher the frequency, the shorter the wavelength
Explanation:
The wavelength and frequency of an electromagnetic wave are inversely proportional to each other.
What is Wavelength and frequency?Wavelength is the distance between any two identical points or adjacent crests in the adjacent cycles of a waveform signal which is propagated in space or along a wire. In the wireless systems, this length is usually specified in the units of meters (m), centimeters (cm) or millimeters (mm).
Frequency is the rate at which the current changes its direction per second time. Frequency is measured in the units of hertz (Hz), an international unit of measure where, 1 hertz is equal to 1 cycle per second of time.
The wavelength in an electromagnetic spectrum is inversely proportional to the frequency of the wave. The shorter the wavelength, the higher the frequency of the wave. Because, all light waves move at the same speed in a vacuum medium, the number of wave crests passing at a given spot in one second is determined by the wavelength of the wave.
