Change in the pressure on the table.

Answer to Problem 91A
Pressure on the table will be increase.
Explanation of Solution
Introduction: Pressure is a perpendicular force applied per unit area on the surface.
Force exerted by a body is the weight of that body.
Since there is no change in the weight of the body pressure will be inversely proportional to the area.
If the area increases, pressure will decrease and if the area decreases, the pressure will increase.
Conclusion:Rectangular box with the small surface area on the table will exert more pressure on the table.

- Compare the slope of your Data Table 2 graph to the average wavelength (Ave, l) from Data Table 2 by calculating the % Difference. Is the % Difference calculated for the wavelength in Data Table 2 within an acceptable % error? Explain why or why not?arrow_forwardThe slope of a graph of velocity, v, vs frequency, f, is equal to wavelength, l. Compare the slope of your Data Table 1 graph to the average wavelength (Ave, l) from Data Table 1 by calculating the % Difference.arrow_forwardExamine the slope of the line on the graph created using the data in Data Table 4 of Period, T2 vs L, the slope of the line is a constant containing the acceleration due to gravity, g. Using the slope of your line, determine the experimental value for g. Compare the value you determined for g from the slope of the graph to the expected value of 9.81 m/s2 by calculating the percent error.arrow_forward
- From your examination of the graph created using the data in Data Table 4 of Period, T vs √L . What would you determine is the relationship between the period of a pendulum and the length of a pendulum?arrow_forwardIn a certain bimetallic strip, the brass strip is 0.100% longer than the steel strip at a temperature of 283°C. At what temperature do the two strips have the same length? Coefficients of linear expansion for steel α = 12.0 × 10−6 K−1 and for brass α = 19.0 × 10−6 K−1 (see Table 13.2).arrow_forwardReview Conceptual Example 2 before attempting this problem. Two slits are 0.158 mm apart. A mixture of red light (wavelength = 693 nm) and yellow-green light (wavelength = 567 nm) falls on the slits. A flat observation screen is located 2.42 m away. What is the distance on the screen between the third-order red fringe and the third-order yellow-green fringe? m = 3 m = 3 m = 0 m = 3 m = 3 Fringes on observation screenarrow_forward
- A film of oil lies on wet pavement. The refractive index of the oil exceeds that of the water. The film has the minimum nonzero thickness such that it appears dark due to destructive interference when viewed in visible light with wavelength 643 nm in vacuum. Assuming that the visible spectrum extends from 380 to 750 nm, what is the longest visible wavelength (in vacuum) for which the film will appear bright due to constructive interference?

UseArchimedes' principle to calculate the mass (in kg) of copper if the top of the wood surface is exactly at thewater's surface?arrow_forwardA filmmaker wants to achieve an interesting visual effect by filming a scene through a converging lens with a focal length of 50.0 m. The lens is placed betwen the camera and a horse, which canters toward the camera at a constant speed of 7.9 m/s. The camera starts rolling when the horse is 36.0 m from the lens. Find the average speed of the image of the horse (a) during the first 2.0 s after the camera starts rolling and (b) during the following 2.0 s.arrow_forward
