Whether it is possible to observe Venus in the sky throughout the entire night from central United States.
Answer to Problem 1RQ
Option (c)
Explanation of Solution
Venus is not a star but a second closest planet from the Sun in our solar system. Stars are located farther away in Milky Way galaxy but Venus is located within our Solar system. Stars has their own light while planets only reflect light from the Sun.
Venus is referred as the morning and evening star because it can be observed shining just before the sunrise in the east for few months and just after the sunset in the west for other months. This happens due to change in orbital position of Venus.
It is visible from Earth because it is close to Earth than other planets and it is also the brightest astronomical body after Sun and moon. It does not twinkle but glows with a silvery light.
Conclusion:
It is never possible to observe Venus in the sky throughout the entire night from central United States because it is only a morning and evening star. Thus option (c) is correct.
Venus is only visible before sunrise and after sunset so it is not sometimes possible to see it entire night. Thus option (a) is incorrect.
Since option (c) is correct. Thus option (b) is incorrect.

- 2. Consider the situation described in problem 1 where light emerges horizontally from ground level. Take k = 0.0020 m' and no = 1.0001 and find at which horizontal distance, x, the ray reaches a height of y = 1.5 m.arrow_forward2-3. Consider the situation of the reflection of a pulse at the interface of two string described in the previous problem. In addition to the net disturbances being equal at the junction, the slope of the net disturbances must also be equal at the junction at all times. Given that p1 = 4.0 g/m, H2 = 9.0 g/m and Aj = 0.50 cm find 2. A, (Answer: -0.10 cm) and 3. Ay.

- Look at the answer and please show all work step by steparrow_forward3. As a woman, who's eyes are h = 1.5 m above the ground, looks down the road sees a tree with height H = 9.0 m. Below the tree is what appears to be a reflection of the tree. The observation of this apparent reflection gives the illusion of water on the roadway. This effect is commonly called a mirage. Use the results of questions 1 and 2 and the principle of ray reversibility to analyze the diagram below. Assume that light leaving the top of the tree bends toward the horizontal until it just grazes ground level. After that, the ray bends upward eventually reaching the woman's eyes. The woman interprets this incoming light as if it came from an image of the tree. Determine the size, H', of the image.
