When a relationship between two different things is shown in a fraction it is a ratio.
hope this helps :)
Answer:
Amoebas have projections called pseudopods
Explanation:
Pseudopodia is the locomatary organ of amoeba. It helps them in movement and transportation.
Answer:
It stays the same.
Explanation:
Entropy of a system either increases or remains constant in any process, it never decreases.
Answer:
ΔE = 1.031 eV
Explanation:
For this exercise let's calculate the energy of the photons using Planck's equation
E = h f
wavelength and frequency are related
c = λ f
f = c /λ
let's substitute
E = h c /λ
let's calculate
E = 6.63 10⁻³⁴ 3 10⁸/1064 10⁻⁹
E = 1.869 10⁻¹⁹ J
let's reduce to eV
E = 1.869 10⁻¹⁹ J (1 eV / 1.6 10⁻¹⁹ J)
E = 1.168 eV
therefore the electron affinity is
ΔE = E - 0.137
ΔE = 1.168 - 0.137
ΔE = 1.031 eV
