In which range is the peak wavelength of a star that is much hotter than the Sun most likely to be? A) radio waves B) infrared radiation C) microwaves D) ultraviolet light

Answers

Answer 1
Answer:

The range in which the peak wavelength of a star that is much hotter than the Sun most likely to be ultraviolet light. Therefore, option (D) is correct.

What is peak wavelength of star?

The peak wavelength is the wavelength at which a radiation source emits the most energy or has the highest intensity. It is related to the temperature of the source through Wien's law, as hotter sources emit shorter wavelengths of radiation.

The peak wavelength of a star is related to its temperature through Wien's law. Wien's law states that the wavelength of the peak intensity of a blackbody radiation curve is inversely proportional to its temperature. Therefore, hotter stars have shorter peak wavelengths than cooler stars. Since ultraviolet light has shorter wavelengths than visible light, stars that are much hotter than the Sun would have their peak wavelength in the ultraviolet range. Thus, the correct option is D) ultraviolet light.

Answers

Answer:

2 out of every 5 or 2/5

Explanation:

there are 200 black cats because there are 300 calico there are 500 total so it would be 200/500 or 2/5

True or false: the resistances measured in this experiment are large. typical values are more than 1000 ω.

Answers

The study of current is called electricity. There are different types of current and these are Alternative current and direct current.

The correct answer is mentioned below.

What is resistance?

  • Resistance is the opposition that a substance offers to the flow of electric current.  It is represented by the uppercase letter R.  
  • The standard unit of resistance is the ohm, sometimes written out as a word, and sometimes symbolized by the uppercase Greek letter omega

According to the question, Since resistance values are typically more than 1000 w so it is true that resistances measured in this experiment are large.

For more information about resistance, refer to the link:-

Dams are barriers that prevent the flow of water. They are created to provide flood control, recreational areas, water for irrigation, and hydroelectric power.Although dams serve many important purposes, they can also have a negative impact on the environment by
A.
preventing fish from moving along a river.
B.
serving as a place for people to have picnics.
C.
increasing fresh water sources for humans.
D.
providing new wildlife habitats.

Answers

Answer:

A. Preventing fish from moving along a river.

Explanation:

1. Dams create barriers and trap the water that builds up behind it. This prevents fish from moving along the river as there's a barrier in place and is just overall harder for the fish to move freely along a river because of it.

2. It's the only negative option as the others are all positive outcomes, while the question asks for a negative outcome instead.

Hope this helps!
