Answer:

Electric current is flow of electrons in a circuit.

Explanation:

Wires are made up of conductors such as copper or aluminum. Atoms of metal are made up of free electrons, which freely move from one atom to the next. If an electron is added in wire, a free electron is attracted to a proton to be neutral. Forcing electrons out of their orbits can cause a lack of electrons. Electrons, which continuously move in wire, are called Electric Current.

Cleaning pumps remove oil at the rate modeled by the function R, given by r of t equals 2 plus the cosine of the quantity pi tim

pychu [463]

Answer:

15.47 gallons

Explanation:

The pumps remove the oil at the rate modelled by

R(t) = 2 + cos(πt / 11) in gallon per hour

The oil removes in 6hours period is given by integral of R(t)

from t = 0 to t = 6

$Q = \int\limits^6_0 {R(t)} \, dt = \int\limits^6_0 {(2+ cos(\frac{\pi t}{11} })) \, dt$

$Q = [2t + \frac{sin(\frac{\pi t}{11}) }{\frac{\pi }{11} } ]_0^6$

$Q = [2(6) + \frac{11}{\pi } sin(\frac{6\pi }{11}) ] - [0 + \frac{11sin (0)}{\pi } ]$

$Q = [12 + \frac{11}{\pi } (0.9898)]\\\\Q = 12 + 3.465694\\\\Q = 15.465694\\\\Q = 15.47 gallons$

Why does the frequency of a siren get higher as an ambulance using that siren gets closer

Nadya [2.5K]

The frequency of a wave becomes higher due to the object moving at a fast pace coming towards you with shorter wavelengths (depending on the speed) aka the Doppler Effect.
Hope this helps
