Quite often advertisements appear for telescopes that extol their magnifying power.
a) Is this a good criterion for evaluating telescopes? Explain your answer.
b) What would be a better criterion for evaluating telescopes? Explain your answer.
(a)Yes , it is a good criterion for telescope because by using these parameter we can use different types of telescope according to our requirement. Because these are evaluated by company in the lab.
(b) A better criterion will be if company will give all the data all information about the telescope and then we can calculate the magnification by our hand and we can compare it with the given data on the telescope. It will be come approximately to the original value.
Magnification = focal length in cm / eye piece diameter in cm
Resolution = 116/D
D= diameter of telescope in mm

Define Light Gathering Power, Magnifying Power and Resolving power in your own words. Do the larger diameter telescopes have bigger or smaller resolving power? Explain why this is a good thing. Do the larger diameter telescopes have bigger or smaller magnifying power? Explain why this is a good thing.
Generally, advertisements for optical (visible light) telescopes frequently give a magnification for the instrument. Unfortunately, this is really not the best information to provide to consumers. Given what you've read about telescopes, identify at least one piece of information that advertisers should cite as criteria by which to evaluate a telescope? Explain your answer.
Telescopes that observe nonvisible types of light work on the same principles as visible telescopes, but they might require different technologies. For instance, instead of lenses or mirrors, a radio telescope (such as the one in the figure) uses technology similar to the television satellite dish you might install on your roof. As with visible light telescopes, bigger radio telescopes yield greater light-gathering power and better angular resolution. However, the angular resolution (θ) of a telescope also depends on the...
Often times when businessmen or women find themselves in positions of power, they use that power for personal gain instead of for the betterment of the company and its employees. Explain in your own words why you think this appears to happen quite often in today’s global marketplace? Do you think the problem is more prevalent than it was a decade ago? Two decades? Support your answer with sound research and real-life examples.
The telescopes on some commercial surveillance satellites can resolve objects on the ground as small as 91 cm across (see Google Earth), and the telescopes on military surveillance satellites reportedly can resolve objects as small as 14 cm across. Assume first that object resolution is determined entirely by Rayleigh's criterion and is not degraded by turbulence in the atmosphere. Also assume that the satellites are at a typical altitude of 403 km and that the wavelength of visible light is...
3. According to advertisements, a commercial hair dressing contains “protein”. Which of the following would be the best test to perform on the product to check this claim? a. The biuret test b. The Millon test c. The Hopkins-Cole test EXPLAIN YOUR ANSWER
The casino game of chuck-a-luck seems quite simple and that it would be a pretty good bet. In this game, three dice are rolled (usually inside a wire cage). You can bet a set amount, let's say $5, on a specific number 1-6. You win the amount of your bet for each appearance of your number on the dice. If the number does not appear, you lose your bet. For example, let's say you bet $5 on the number 3....
Your company has been struggling financially for quite some time now. You have a chance of meeting expectations and making a profit this quarter, which is sure to bolster your stock’s sagging price. But it depends on your using a waste disposal practice that is both unquestionably legal and unquestionably harmful to the environment. What would you decide to do and why? Give a "good, better, best" scenario from a leader's perspective.

(a) discuss the factors affecting group cohesiveness and explain how each of them would affect group cohesiveness. (18 marks) (b)Explain the relationship between group cohesiveness, performance norms and group performance. (8 marks)
