Document Summary

Everybody in contemporary society has their point of view and perspective on any given subject. As a result of these divergent viewpoints and beliefs, healthy debates emerge, allowing society to progress. The disparity in perspectives on what people consider moral or immoral in the community is a hot topic. Hobbes and kant are two well-known philosophers who have opposing views on human nature and reasoning. Thomas hobbes provides a practical perspective on this problem, believing that when a person is in or has authority, they should do good. On the other hand, immanuel kant takes a robust rationalistic approach, believing that good comes from the desire for anything in life (hobbes & gaskin, 1998). This paper analyzes and contrasts thomas hobbes" and immanuel kant"s perspectives on what is desirable in a community. After analyzing their differing perspectives on what constitutes "excellent," the paper determines who has the more straightforward explanation.

A helium-neon laser (? = 633 nm), shown in Fig. P17.73, is builtwith a glass tube of inside diameter 1.0 mm. One mirror ispartially transmitting to allow the laser beam out. An electricaldischarge in the tube causes it to glow like a neon light. From anoptical perspective, the laser beam is a light wave that diffractsout through a 1.0-mm-diameter circular opening.

a. Explain why a laser beam canât be perfectly parallel, with nospreading.

b. The angle ?1 to the first minimum is called the divergence angleof a laser beam. What is the divergence angle of this laserbeam?

c. What is the diameter (in mm) of the laser beam after it travels3.0 m? d. What is the diameter of the laser beam after it travels1.0 km?

a candle is placed in front of a convex mirror.

A candle is placed in front of a convex mirror.

Figure6 of 6The figure labeled C shows two rays coming out of the top of the object in front of the concave mirror, forming an acute angle with the axis. Upper ray reflects parallel to the axis. And the lower ray reflects in the direction exactly opposite to its initial direction. There is a focus point F on the axis in front of the mirror and a center of the mirror’s curvature C between point F and the object. The image is smaller, than the object, located between points F and C, and inverted, its tip is formed by intersection of the reflected rays. The initial upper ray passes through point F and the initial upper ray passes through point C. The figure labeled C shows two rays coming out of the top of the object in front of the concave mirror, forming an acute angle with the axis. Upper ray reflects parallel to the axis. And the lower ray reflects in the direction exactly opposite to its initial direction. There is a focus point F on the axis in front of the mirror and a center of the mirror’s curvature C between point F and the object. The image is smaller, than the object, located between points F and C, and inverted, its tip is formed by intersection of the reflected rays. The initial upper ray passes through point F and the initial upper ray passes through point C.

Part A Consider the following diagrams noting that the scale is different between diagrams. In these diagrams, C and F represent the center of curvature and the focal point of the convex mirror, respectively. The image formed by the mirror is obtained using the ray tracing technique. Which diagram(s) are correct?(Figure 1) (Figure 2) (Figure 3) Type A if you think that only diagram A is correct, type AB if you think that only diagrams A and B are correct, and so on.

Part B If the radius of curvature of the convex mirror is 50.0 cm , at what distance do from the mirror must the candle be placed so that its image is formed 20 cm from the mirror? Express your answer in centimeters. View Available Hint(s) dod o d_o = cm The convex mirror is now replaced by a concave mirror with the same radius of curvature.

Part C Consider the following diagrams, where now C and F represent, respectively, the center of curvature and the focal point of the concave mirror. Again, the image formed by the mirror is found by ray tracing. Choose the correct diagram(s).(Figure 4) (Figure 5) (Figure 6) Type A if you think that only diagram A is correct, type AB if you think that only diagrams A and B are correct, and so on.

Part D Assuming that the candle remains at a distance do from the mirror (the same distance found in Part B), at what distance di from the mirror will its image form now? Express your answer in centimeters. View Available Hint(s) did i d_i = nothing cm

I tried to solve this problem twice but i can't get the rightresults.

If a person of mass M simply moved forward with speed V, hiskinetic energy would be 1/2MV² . However, in addition topossessing a forward motion, various parts of his body (such as thearms and legs) undergo rotation. Therefore, his total kineticenergy is the sum of the energy from his forward motion plus therotational kinetic energy of his arms and legs. The purpose of thisproblem is to see how much this rotational motion contributes tothe person's kinetic energy. Biomedical measurements show that thearms and hands together typically make up 13.0% of a person's mass,while the legs and feet together account for 37.0% . For a rough(but reasonable) calculation, we can model the arms and legs asthin uniform bars pivoting about the shoulder and hip,respectively. In a brisk walk, the arms and legs each move throughan angle of about Â±30^o (a total of 60^o ) fromthe vertical in approximately 1 second. We shall assume that theyare held straight, rather than being bent, which is not quite true.Let us consider a 75.0 person walking at 5.00km/h having arms70.0cm long and legs 90.0cm long.

A)What is the average angular velocity of his arms and legs?

B)Using the average angular velocity from part A, calculate theamount of rotational kinetic energy in this person's arms and legsas he walks.

C)What is the total kinetic energy due to both his forwardmotion and his rotation?

D)What percentage of his kinetic energy is due to the rotationof his legs and arms?

If you want to help, you don't need to solve the whole problem.Just explain how to solve. If you understand or know how to solvethis problem, please help.
