Will you please mark me as brainliest or thank me. i can’t post a question until someone does and i’m so confused on my question i really need you to please
Answer:
an expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s).
Answer:
λ = 5.75 10⁻⁷ mm
Explanation:
This is a slit interference exercise, we analyze each wavelength separately
λ = 657 nm indicate that the third dark pattern
a sin θ = (m + ½) lam
a sin θ = (3 + ½) 657 10⁻⁹
a sin θ = 2299.5 10⁻⁹ nm
for the other wavelength in the same place we have m = 4 bright
a sin θ = m lam
we substitute
2299.5 10⁻⁹ = 4 λ
λ =
λ = 5.75 10⁻⁷ mm
Although Alfred Wegener was considered as the "Father of the Plate Tectonics Theory", his theory was furthermore revised by Arthur Holmes. It was this scientist who suggested that the plate motions could be subjected from convection currents on the mantle. These convection currents would lead to the formation of different landforms.
Answer:
In positive feedback mechanism, the output is fed back to the system which further increases the output. Hence, it is known as positive feedback because it amplifies the output.
In the negative feedback mechanism, the output is fed back to the system which further decreases the the output. Hence, it is known as negative feedback because it reduces the output.
