Life Cycle of a Star for medium mass stars

Answers

Answer 1
A star's life cycle is determined by its mass. The larger the mass, the shorter the life cycle. It is now called a main sequence star and will remain in this stage, shining for millions or billions of years to come. As the main sequence star glows, hydrogen in the core is converted into helium by nuclear fusion.

The celerity (speed) of a deep water wave with a wavelength of 100m and a period of 10 seconds is: (choose correct answer)
options:
100m/s
10m/s
1000m/s
1m/s

Answers

Answer:

I think option 3 as I guess

The celerity (speed) of a deep water wave with a wavelength of 100m and a period of 10 seconds is 1000m/s. Hence, option C is correct.

What is wavelength?

A waveform signal that is carried in space or down a wire has a wavelength, which is the separation between two identical places (adjacent crests) in the consecutive cycles. This length is typically defined in wireless systems in meters (m), centimeters (cm), or millimeters (mm) (mm).

The wavelength, which will also apply to troughs, is the separation between two wave crests. The frequency is measured in cycles per second (Hz), which is the quantity of vibrations that cross a specific area in a second.

Examples of wavelengths. The wavelength range of all visible light is 400 to 700 nanometers (nm). The wavelength of yellow light is 570 nanometers or such. "Redder than red" or infrared energy is energy with a wavelength that is too long to see.

Thus, option C is correct.

Which of the following processes causes the Earth's tectonic plates to move?
A. the daily cycle of high and low tides
B. convection currents in the Earth's mantle
c. the continuous flow of ocean currents
D. high pressure in the atmosphere

Answers

B. Convection currents in the earths mantle

Convection currents in the Earth's mantle processes causes the Earth's tectonic plates to move. Option (b) is correct.

What do you mean by Tides?

The twice daily regular rise and fall of ocean water is known as a tide. The tides are caused by the sun and moon's powerful gravitational pull on the surface of the earth.

The molten rock in the mantle, below the crust, is known as magma. Convection currents are created by the intense heat and pressure that exists within the earth. The tectonic plates that make up the earth's crust shift as a result of these currents.

The science of rock and other material movement beneath the surface of the Earth is known as plate tectonics. Huge rock slabs known as tectonic plates cover the partially molten Earth's mantle, which is located under the crust.

Therefore, Option (b) is correct. Convection currents in the Earth's mantle.

Indicate three shortcoming of hachures.​

Answers

Answer:

Hachures don't indicate the Absolut heights thus regions like the hills and plateaus don't have the same elevation. In the hilly countries, the hachures obstruct the details of topography. They take a long time to drawn and are costly.

Explanation:

A hachure is a mode of relief representation. It shows the orientation of the slope and thickness over the density. It provides a sense of steepness. They represent forms of shading ad can be sued with different maps. These are done traditionally in mono color.

Hachures are lines drawn in the direction of the steepest slope. Thicker, shorter strokes symbolize steeper slopes, whereas thinner, longer and farther spaced strokes reflect gentler slopes.

Hachures do not show absolute heights, places such as hills and plateaus do not have the same elevation.The hachures impede the intricacies of topography in hilly countries.They cost a lot of money and take a long time to draw.

Both systems set specific property boundaries for landholders. However, the metes-and-bounds system is more orderly and efficient.

Both systems require geometric calculations to survey property lines. However, the township-and-range system uses simplified calculation to create a more ordered landscape.

Both systems require geometric calculations to survey property lines. However, only properties surveyed with the metes-and-bounds system can be subdivided into smaller plots.

Civil and criminal cases are heard in secular courts, while the Sharia courts handle personal, family and religious matters in cases between Muslims or between Muslims and non-Muslims. Non-Muslim communities have their own religious courts using their own religious law. Secular legal systems are legal systems without religion, but not without God. Secularization means not using the name of God as a legal concept. God is no longer the starting point of a secular legal system, but he can continue being a source of light for it.
