To Explain:The slope of the graph.

Answer to Problem 72A
The slope will be zero.
Explanation of Solution
Introduction:
Slope is calculated by the ratio of the vertical change versus the horizontal change in the values of the variables when plotted on a graph.Slope measures the relation between two variables. Whether it is positive, negative or zero.
A positive slope represents a direct relation which means that when one variable increases, the other variable also increases. Negative slope represents an inverse relation which means that one variable increases, the other variable decreases. A slope of zero means that there is a constant relationship.
In this case value of the y axis is the same for each value of the independent variable, so the slope will be zero as the vertical change is zero.
Conclusion:
Hence, the slope is zero and y does not depend on x.

- Hi! I need help with these calculations for part i and part k for a physics Diffraction Lab. We used a slit width 0.4 mm to measure our pattern.arrow_forwardExamine the data and % error values in Data Table 3 where the angular displacement of the simple pendulum decreased but the mass of the pendulum bob and the length of the pendulum remained constant. Describe whether or not your data shows that the period of the pendulum depends on the angular displacement of the pendulum bob, to within a reasonable percent error.arrow_forwardIn addition to the anyalysis of the graph, show mathematically that the slope of that line is 2π/√g . Using the slope of your line calculate the value of g and compare it to 9.8.arrow_forward
- An object is placed 24.1 cm to the left of a diverging lens (f = -6.51 cm). A concave mirror (f= 14.8 cm) is placed 30.2 cm to the right of the lens to form an image of the first image formed by the lens. Find the final image distance, measured relative to the mirror. (b) Is the final image real or virtual? (c) Is the final image upright or inverted with respect to the original object?arrow_forwardConcept Simulation 26.4 provides the option of exploring the ray diagram that applies to this problem. The distance between an object and its image formed by a diverging lens is 5.90 cm. The focal length of the lens is -2.60 cm. Find (a) the image distance and (b) the object distance.arrow_forwardPls help ASAParrow_forward
