Farenheit is the best to measure accurate temperature because, It can go into the negatives(-) and unlimited positives(+). Celcius(C) only goes from 0-100°C Stating that water freezes at 0°C and Boils at 100°C. Farenheit has unlimited temperatures because as time goes by we continue making new discoveries in science.
I Hope This Helps!!! :)

Answer:
1. λ = 0.48 cm = 4800 μm
2. υ = 6.25 x 10¹⁰ Hz
3. E = 4.14 x 10⁻²³ J
Explanation:
1.
Since, the wavelength is defined as the distance between two consecutive or successive crests or troughs. Therefore, in this case the wavelength will be equal to:
Wavelength = λ = Distance between 5 successive crests/5
λ = 2.4 cm/5
<u>λ = 0.48 cm = 4800 μm</u>
<u></u>
2.
The frequency of photon can be given as:
υ = c/λ
where,
υ = frequency of photon = ?
c = speed of light = 3 x 10⁸ m/s
λ = wavelength = 0.48 cm = 0.0048 m
Therefore,
υ = (3 x 10⁸ m/s)/(0.0048 m)
<u>υ = 6.25 x 10¹⁰ Hz</u>
<u></u>
3.
Now, the energy of photon is given as:
E = hυ
where,
E = Energy = ?
h = Plank's Constant = 6.626 x 10⁻³⁴ J.s
Therefore,
E = (6.626 x 10⁻³⁴ J.s)(6.25 x 10¹⁰ Hz)
<u>E = 4.14 x 10⁻²³ J</u>
Answer:
All mammals share at least three characteristics not found in other animals: three middle ear bones, hair, and the production of milk by modified sweat glands called mammary glands. Hair has several functions, including insulation, color patterning, and aiding in the sense of touch.

Answer:
It is the third-lightest halogen, and is a fuming red-brownliquid at room temperature that evaporates readily to form a similarly coloured gas. Its properties are thus intermediate between those of chlorine and iodine. .
