Answer:
270°
Explanation:
A full rotation is 360° so half (2/4) of it is 180° meaning a quarter (1/4) is 90°
So you can do 90+90+90=270
or 180+90=270

Answer:
E = 2.48 eV
Explanation:
The energy of a photon is given by the following formula:
E = hυ
where,
E = Energy of Photon = ?
h = Plank's Constant = 6.626 x 10⁻³⁴ J.s
υ = frequency of photon = c/λ
Therefore,
E = hc/λ
where,
c = speed of light = 3 x 10⁸ m/s
λ = wavelength of light = 500 nm = 5 x 10⁻⁷ m
Therefore,
E = (6.626 x 10⁻³⁴ J.s)(3 x 10⁸ m/s)/(5 x 10⁻⁷ m)
E = (3.97 x 10⁻¹⁹ J)(1 eV/1.6 x 10⁻¹⁹ J)
<u>E = 2.48 eV</u>
Answer:
The ozone appears in Antarctica during the Arctic spring.
Explanation:
From September to early December, strong winds start to circulate around the Arctic and creates an atmospheric container.
