How do you solve for x and y in an angle?
If X and Y are sides of a right triangle, R is the hypoteneuse, and theta is the angle at the X-R vertex, then sin(theta) is Y / R and cosine(theta) is X / R. It follows, then, that X is R cosine(theta) and Y is R sin(theta)

In a plot of ln(k) vs. 1T a slope of and ndash4.3 x 102 K is obtained. What is the activation energy for this reaction?
The activation energy can be determined using the Arrhenius equation: ln(k) = -Ea/R x (1/T) + ln(A). From the given slope of -4.3 x 10^2 K, we have -Ea/R = -4.3 x 10^2, so Ea = 4.3 x 10^2*R, where R is the gas constant, 8.314 J/mol-K. Calculating Ea gives a value of approximately 3575 J/mol.
What is physical meaning of slope for voltages vs current graphs?
The slope of a voltage vs. current graph represents the resistance in the circuit. It indicates how the voltage changes with respect to the current flowing through the circuit. A steeper slope indicates higher resistance, while a shallower slope indicates lower resistance.
What does the slope of a graph potential difference vs current represent?
The slope of a graph of potential difference vs current represents the resistance of the component or circuit being analyzed. It is calculated using Ohm's Law: V = IR, where V is the potential difference, I is the current, and R is the resistance. A steeper slope indicates a higher resistance, while a shallower slope indicates a lower resistance.

What is the definition of R-ratio in fatigue analysis?
When looking a stress vs. time plot of the fluctuating stress diagram (that has the graph of the sine curve. The R ratio is the minimum stress divided by the maximum stress. R = (SIGMAmin/SIGMAmax)
The circling of one object about another?

It decreases Fg=Gm1m2/r^2
Use an Arrhenius plot to determine the activation barrier for the reaction?
To determine the activation energy barrier for a reaction using an Arrhenius plot, measure the rate constants at different temperatures and plot ln(k) against 1/T. The slope of the resulting line is equal to -Ea/R, where Ea is the activation energy and R is the gas constant. By rearranging this equation, you can calculate the activation energy barrier for the reaction.
What description of a scientific law that uses a math equation?
Law of Gravity: Fg = G(m1*m2)/r^2
What effect does R have on the sawtooth?
The constant R in the sawtooth wave formula affects the slope of the rising edge of the wave. A higher R value will result in a steeper rising edge, while a lower R value will create a more gradual slope.
Does a spiral staircase have a constant slope?
Previous answer: "No because the line is not straight and the points of the slop is in different ares." The above is ambiguous. You need to define the term slope. The slope of a helix (or any curve) is normally defined as the slope of a line that is tangent to the helix (curve). And then you need to define, slope with respect to what? Normally that would be slope with respect to a horizontal plane. That slope, by definition, is constant for a helix with a vertical axis. The value of the slope of such a helix is pitch / (2*pi*R), where R is the radius from the axis. Then you have to consider where on the staircase you are. A staircase is not a single helix. It has width, or different radii. If you are walking up stairs at a constant radius R from the axis (on a helix), then the slope is constant. In any case, the average slope of the stairs varies with the radius R on which you are walking, so that would not be a constant.
