The correct option for the statement “Sedimentary rocks often contain the remains of ancient life forms-fossils. And fossils in these rocks help us understand.”

Answer to Problem 10RAT
The correct option for the statement “Sedimentary rocks often contain the remains of ancient life forms-fossils. And fossils in these rocks help us understand” is option (d).
Explanation of Solution
The fossils are used in the study of geology as they are made of remains of organic species from the past. They help to determine the Earth’s geologic history. They can indicate that from where and how sediment is formed or deposited. They additionally assist in classifying same kind of rocks from distinct places that are of comparable geologic age. Hence, fossils are very useful in the study of geology.
Conclusion:
Therefore, the correct option for the statement “Sedimentary rocks often contain the remains of ancient life forms-fossils. And fossils in these rocks help us understand” is option (d).

- 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

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_forward

Using the slope of your line calculate the value of g and compare it to 9.8.arrow_forwardAn 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_forward
