Water pollution is a major problem resulting from the oil industry in eastern Alberta, Canada.
Hope it helps!
the basic measurements of length, volume, and mass are 1 meter, 1 meter³ and 1kilogram.
One 10-millionth of the distance from the North Pole to the equator would equal one meter.
A cube with sides of one meter has a volume of one meter³.
The mass of 1,000 cubic centimeters of water is very close to (and was originally intended to be exactly) one kilograms.
but today a more precise way to define is available in which:
1 meter is defined as the distance traveled by light in 1/3×10⁸ sec.
The weight of a specific platinum-iridium prototype held by the International Bureau of Weights and Measures is defined as 1 kg.
moreover these measurements are man made and are not absolute and therefore many new units of measurement can be defined as long as they are fundamentally same everywhere.

A galvanic cell is formed when two metals are immersed in solu- tions differing in concentration 1 when two different metals are immersed.
<h3>What is galvanic cell?</h3>
- The galvanic cell utilizes the ability to split the flow of electrons in the process of oxidization and reduction, compelling a half-reaction and connecting each with a wire so that a way can be formed for the flow of electrons via such wire.
- A galvanic cell is an electrochemical cell that transforms the chemical energy of a spontaneous redox response into electrical energy. It has an electrical possibility equal to 1.1 V. In galvanic cells, oxidation occurs at the anode and it is a negative plate. Lessening occurs at the cathode and it is a positive plate.
- A galvanic cell is an electrochemical cell that converts the free liveliness of a chemical method into electrical energy. A photogalvanic cell generates species photochemically which react resulting in an electrical current via an external circuit.

Because acceleration is constant, the acceleration of the car at any time is the same as its average acceleration over the duration. So
Now, we have that
so we end up with a distance traveled of
Answer:
n1 sin θ1 = n2 sin θ2 Snell's Law (θ1 is the angle of incidence)
sin θ2 = n1 / n2 * sin θ1
sin θ2 = 2.4 / 1.33 * sin θ1
sin θ2 = 1.80 * .407 = .734
θ2 = 47.2 deg
