What is the largest dimension of which you have personal knowledge? Have you run a mile? Hiked 10 miles? Run a marathon?
To tell about the largest dimension that we have personal knowledge. We need to tell about a mile,hiked 10 miles and run a marathon when we run a distance.
Answer to Problem 1RQ
The largest dimension based on personal knowledge is mile or kilometer. A normal person can easily run a mile in routine. For hike 10 miles, small practice is required but for run the marathon, regular practice is required based on gradual increase in the miles.
Explanation of Solution
The largest dimension based on personal knowledge is mile or kilometer because in a normal routine a person may walk or run 3 to 4 miles. There is another fact that the next dimension after kilometer is megameter which is 1000 times of kilometer (approximately is equal to the radius of the Earth). To run a megameter is impossible for any person at personal level in the World.
Yes, we (as a normal person) have run a mile in our routine. This is essential because a mile is equal to 1.6 kilometer (approximately) but when we hike this distance by 10 miles then it will not be so easy for a normal person. I have run 10 miles only once.
Normally, marathon run lies between 26 miles to 30 miles. I have never run a marathon because for this run, a regular practice is required. To achieve the target of marathon, we should start the run-practice from 5 miles and should increase the distance gradually on weekly basis.
Hence, we conclude that the largest dimension based on personal knowledge is mile or kilometer. A normal person can easily run a mile in routine. For hike 10 miles, small practice is required but for run the marathon, regular practice is required based on gradual increase in the miles.
Conclusion:
The largest dimension based on personal knowledge is mile or kilometer. A normal person can easily run a mile in routine. For hike 10 miles, small practice is required but for run the marathon, regular practice is required based on gradual increase in the miles.

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. (Answer: 0.40 cm)please I need to show all work step by step problems 2 and 3arrow_forward

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. (Answer 8.8 m) please show all work step by steparrow_forward
