What is the energy of one photon of red light that has a wavelength of 678 nm?

Vitek1552 [10]

Answer:

E = 2.93×10⁻¹⁹ J

Explanation:

Given data:

Wavelength of photon = 678 nm (678×10⁻⁹ m)

Energy of photon = ?

Solution:

Formula:

E = h c/λ

h = 6.63×10⁻³⁴ Js

c = 3×10⁸ m/s

E = 6.63×10⁻³⁴ Js × 3×10⁸ m/s / 678×10⁻⁹ m

E = 19.89 ×10⁻²⁶ Jm / 678×10⁻⁹ m

E = 0.0293×10⁻¹⁷ J

E = 2.93×10⁻¹⁹ J

The R group or side chain of the amino acid leucine is non-polar. The R group of serine is polar. Where would you expect to find

Pani-rosa [81]

Answer:

Serine will be on the exterior of the globular protein while leucine on the interior of the globular proteins

Explanation:

The nature or solubility of the side cham determines the poition of amino acid on the globular protein and it is either hydrophilic or hydrophobic.

Serine is an hydrophilic amino acid and so it is position on the surface of the globular protein (Exterior)

While Leucine side chain is hydrophobic in nature is positioned on the interior of the globular protein.

Find the density of a cube on Earth that weighs 1.5 kg and has a side-length of 10 cm.

Inga [223]

Answer:

1.5g/cm³

Explanation:

density=mass÷volume

mass= 1.5kg (change into g) = 1500g

volume of the cube = 10×10×10 = 1000cm³

density= divide 1500g÷1000cm = 1.5g/cm³

<h2>Density= 1.5g/cm³</h2>

YOUR WELCOME!
