Catalysts are used in the oil industry to increase octane
ratings in gasoline. Octane ratings tell how much fuel has to be compressed to
promote better fuel ignition in some
cars. The catalytic effect that
would be most beneficial for the oil industry is that more products can be
formed from a given amount of material.
The correct answer for the question that is being presented above is this one: "a. the wavelength of light emitted by the star." The mass of a star can be determined by studying <span>the wavelength of light emitted by the star. It also has something to do with the gravitational force that it exerts.</span>
Answer:
a = 12 [m/s²]
Explanation:
To solve this problem we must use Newton's second law which tells us that the sum of forces on a body is equal to the product of mass by acceleration.
ΣF = m*a
where:
ΣF = sum of forces acting on a body [N] (units of Newtons)
m = mass = 0.5 [kg]
a = acceleration [m/s²]
Let's take the direction of positive forces to the right and negative forces directed to the left
2 + 8 - 4 = 0.5*a
6 = 0.5*a
a = 12 [m/s²]
Less than 7, Ph of 7 is neutral Acid Rain would be between 4 and 0.
