Answer:
Im pretty sure that 5N to the Right is correct answer
(of a river or road) follow a winding course
Wavelength of the light is 2.9 × 10⁻⁷ m.
<u>Explanation:</u>
Planck - Einstein equation shows the relationship between the energy of a photon and its frequency, and they are directly proportional to each other and it is given by the equation as E = hν,
where E is the energy of the photon
h is the Planck's constant = 6.626 × 10⁻³⁴ J s
ν is the frequency
From the above equation, we can find the frequency by rearranging the equation as,
ν =
= 
Now the frequency and the wavelength are in inverse relationship with each other.
ν × λ = c
It can be rearranged to get λ as,
λ = c / ν
= 
So wavelength is 2.9 × 10⁻⁷ m.
Answer:
Option (B)
Explanation:
Felsic magma refers to those magma that are comprised of more than 65% of silica content and are highly made up lighter elements like oxygen, silicon, sodium, aluminum, potassium, and are light-colored in comparison to the basic magma. Due to its high silica content, these are high viscosity magma and flows at a much slower rate. The felsic magma crystallizes at a relatively low-temperature rocks and the rocks that are formed from this type of magma have a specific gravity of less than 3.
Thus, the correct answer is option (B).
