PIT_PIT [208]2 years ago
5 0

Answer:

1. Yes, BEVs or hydrogen fuel cell vehicles are a more promising transportation technology for the future.

2. Yes, car companies should be require to produce electric cars.

Explanation:

  • BEV stands for battery electric vehicle which is a type of electric vehicle. These vehicle and hydrogen fuel vehicles are a promising transportation technology for future as traditional vehicles along with other factors have polluted the earth so much that now we have to minimize the carbon footprint. The natural resources of fuel are also getting scare. So, these batteries assisted and eco-friendly are the need of the present and are vital in playing a important role in transportation in future.
  • Car companies should be require to produce electric cars as some companies like Tesla has already their electric car in the market lately. The countries in the scandinavian region have adopted the policy to promote and use this vehicles so company come forward to provide eco-friendly and price competitive vehicles so everyone can take the advantage.

A large fraction of the ultraviolet (UV) radiation coming from the sun is absorbed by the atmosphere. The main UV absorber in ou
irakobra [83]

Answer:

λ = 3.2 x 10⁻⁷ m = 320 nm

Explanation:

The relationship between the velocity of electromagnetic waves (UV rays) and the their frequency is:

v = fλ

where,

v = c = speed of the electromagnetic waves (UV rays) = speed of light

c = 3 x 10⁸ m/s

f = frequency of the electromagnetic waves (UV rays) = 9.38 x 10¹⁴ Hz

λ = wavelength of the electromagnetic waves (UV rays) = ?

Therefore, substituting the values in the relation, we get:

3 x 10⁸ m/s = (9.38 x 10¹⁴ Hz)(λ)

λ = (3 x 10⁸ m/s)/(9.38 x 10¹⁴ Hz)

<u>λ = 3.2 x 10⁻⁷ m = 320 nm</u>

So, the radiation of <u>320 nm</u> wavelength is absorbed by Ozone.

Why is it important that radioisotopes used in diagnostic tests have short half-lives? 20 A) These radioisotopes have a greater
LiRa [457]

Answer:

Option B) This minimizes the harmful side effects of the radiations

Explanation:

Half-life is the time taken for the decay of an radio-active atom in which it disintegrates such that it becomes half of its value at the beginning.... The nuclei should be in active mode for a longer duration sufficient for the treatment of the condition but these nuclei should have a sufficient  shorter half life so that they don't get enough time to cause any  damage to the health of the person other than treating the cause.

A shorter half life gives the assurance that the radiation after the treatment will leave the body without getting accumulated and cause harm to the body cells and other organs.
