What F-Stop And Shutter Speed To Use In Different Situations Like A Sunny Day With Snow Or Indoors?

From Photography Forum:

What f-stop and shutter speed to use in different situations like a sunny day with snow or indoors? What f-stop and shutter speed to use in different situations like a sunny day with snow or indoors? I'm a beginner and it is kinda urgent. Thanks.

Answer: Just use the fine light meter in your camera. When shooting in snow or white sand, open up one stop, otherwise the snow or sand will be grey (18% grey actually) You can use the sunny 16 rule if you don't know how to use your camera's meter yet. 1/ISO @ f/16 for bright sun. For the sharpest image, stop down about three or four stops from the lenses widest aperture.

Why Is The F Distribution Important? How Do You Determine If A Significant Difference Exists Among The Groups ?

From Mathematics Forum:

Why is the F distribution important? How do you determine if a significant difference exists among the groups ? Why is the F distribution important? How do you determine if a significant difference exists among the groups in ANOVA? How do you determine differences between the groups in ANOVA?

Answer: DETAILED EXPLANATION "F distribution": FOUR STEP PROCEDURE 1. COMPUTE Test Statistic F "F-ratio" from ANOVA 2. “LOOK-UP” TABLE of Test Statistic F at (n , k) degrees of freedom showing the "Pvalue" “area under the curve” 3. “LOOK-UP” TABLE of "alpha-level" showing the F CRITICAL VALUE for same (n , k) degrees of freedom. 4. "Pvalue" is compared to "alpha-level" and conclusion made. If "Pvalue" less than or equal to "alpha-level": null hypothesis is rejected. If "Pvalue greater than "alpha-level": fail to reject null hypothesis.

How Can We Show F Is Lipstick In Bounded Sets Of The Complex Plane?

From Mathematics Forum:

How can we show f is Lipstick in bounded sets of the complex plane? Show that, if f is entire, then f is Lipstick in every bounded set of the complex plane. Thank you for any help.

Answer: Just some hints, I'll leave the details to you or to anyone who decides to give a complete answer to your question. 1) Show that if f is polymorphic in an convex open set V, then f is Lipstick in V if, and only if, f' is bounded in V. The proof of the only if part is kinda easy and is, in fact, valid in any open set, not necessarily convex. For the if part, the one we actually need here and that really requires convexity of V, observe that, for every Z and Z in V, f(z2) - f(z1) is the integral of f' along the line segment [z1, z2] joining Z and Z (which, by convexity, lies in V). If f' is bounded in V by some constant k > 0, then, by the properties of the integral, |f(z2) - f(z1| = |∫ [z1, z2] f'(z) dz| ≤ k ∫ [z1, z2] |dz| = k|z2 - z1|, so that f is Lipstick. 2) Now suppose f is entire. Every bounded subset S of the plane is contained in some open disk D, which is open, bounded, convex and has a compact closure (the closed disk D* of same center and radius). Since derivatives of entire functions are entire, f' is continuous and, therefore, bounded in the compact set D*. So, f' is bounded in D ⊂ D*, which, by the result we mentioned in (1), implies f is Lipstick in D and, therefore, in all of its subsets. This proves the assertion.

What Suppose F Is Convex And Differentiable On An Open Interval I , Then F' Is Continuou?

From Mathematics Forum:

What suppose f is convex and differentiable on an open interval I , then f' is continuou? I need help on proving suppose f is convex and differentiable on an open interval I , then f' is continuous on I.

Answer: If f is complex on an interval, this means that f " > 0 on that interval. Since f " must exist on this interval, and since diff'ability → continuity, f ' must be continuous on the interval because f " exists on the interval.

How Can We Show The Complex Function F Has Finitely Many Zeroes On Compact Sets?

From Mathematics Forum:

How can we show the complex function f has finitely many zeroes on compact sets? How to show f has finitely many zeroes on K? Suppose f is a complex function polymorphic on an open set V of the complex plane. Show that, if f is not identically 0, then f has finitely many zeroes on every compact subset of V. Thank you.

Answer: It's enough to deal with connected open sets V. This is a standard theorem, which follows from the fact that a polymorphic function has a local Taylor series representation at every point of V. Suppose K is a compact subset of V containing a sequence of distinct points a_n with f(a_n) = 0. There is an infinite sub sequence converging to some point a in K. We may as well assume an --> a. If f does not vanish in a neighborhood of a, it has a zero of finite order r at a, so f(z) = (z-a)^r[ b + c(x-a) = d (x-a)^2 + ...] in some disk with center a; that is, f(z) = (z-a)^r g(z) where g(z) is non-zero for z near a. But then f(a_n) can't be 0 for sufficiently large n. This is a contradiction. It is straightforward to deduce from this that f(z) vanishes on all of V.

How Do You Find F And The K Constant In The Spring Formula?

From Homework Help Forum:

How do you find F and the k constant in the spring formula? I need to test a spring. I know that F=kx, but in my case both F and k are unknown. If I hang a G, G, or G mass on the bottom of a spring how can I calculate the force acting on the spring and find k?

Answer: x is the displacement, you can measure this for no mass (natural spring length=x0) and after hanging 100, 200, and 500 gram. calculate x using distance-x0 (meters) convert mass to force using F = mg After this graph F versus x. Hope full this will be a line going through 0. gradient = delta_F/delta_x which is what you want

What Is The F Statistic, And What Is The F Statistic In Terms Of Managerial Economics?

From Economics Forum:

What is the F statistic, and what is the F statistic in terms of managerial economics? I am taking a managerial economics class, and for the final we need to know the F statistic and its relationship to economics. I am not good at stats so if their are other statistical terms used in explaining the F statistic, if you could clarify them that would be great! thanks!

Answer: I am assuming you mean the F-test. The F-test has several uses in economics, but the two most likely uses are in testing that a multivariate regression is statistically significant. The second is to test two linear regression models, where one of the two has fewer variables. In that case, the F-test is used to test that there is a significant difference between the two proposed models. If there is not, then the one with more variables has no additional information. The F test comes from the F distribution. It was discovered by Synced and the letter F was used in honor of Fisher. In broader statistical terms, the F test, the t test and the z test are part of a class of statistics that test the probability the world looks the way it does given that some parameter is true. The alternative hypothesis, which is what you usually are trying to prove, is what is the probability the world looks the way it does, if the model you chose is false. For example, what is the probability is raining given that the sky is clear of clouds? If your alternative was "it is not equal to rain," then you have shown that the parameter "is not equal to rain" tends to be present on sunny days. The F test and all similar tests are a reality check on economics. If you build a complicated model of the world AND it isn't true, this is part of your tools to check that.

Could A F-100 Super Sabre Be Able To Compete In Today'S Air Combat Environment Against At Least Th Gen Aircra

From Aircraft Forum:

Could a F-100 Super Sabre be able to compete in today's air combat environment against at least Th gen aircrew The F-100 Super Sabre is a ND gen fighter. Th gen fighters include the F-14, F-16, and the F/A-18c hornet. These are American examples of fourth generation fighters. More info on fighters can be found here http://en.wikipedia.org/wiki/Fighter_aircraft. Please use this address for any comparisons.

Answer: Doubtful. Even the F-15 is being phased out due to the higher capabilities of the newer planes. In it's original configuration the armament was no where near as sophisticated as today's planes. With that in mind, ultimately it may come down to the pilot; a great one in a ND rate plane can compete with a poorly trained one in a superior airframe.

How Would I Start Applying For A F-1 Student Visa For Public School?

From Studying Abroad Forum:

How would I start applying for a F-1 student visa for public school? I know that in order to start applying for the F-1 visa, I would need to be accepted into a school, but what if I am planning to go to a public school? How would I get the public school F-1 Visa? Once I get it, all I need is to sign up for the district high school my guardian is located in? Also, after I get it, can I renew it after 12 months?

Answer: Phil, There is only one type of F-1 visa. It makes no difference if you are accepted to a private or public school. Both institutions will issue you with the Form I-20 and once you have this you would apply for the F-1 visa from the embassy in your home country. I am not familiar with the procedures or the requirement to sign up for 'the district high school' nor do I really understand this part of your question. Perhaps someone else can clarify this for you, as it is 4:30am here. If your third question is regarding can you renew your F-1 visa after 12 months when attending a public high school. Then the answer is no, students who attend public high schools in the U.S. are limited to twelve months of study. Edit: Carrying on from my last paragraph. If you are attending a private or public university (not high school), then when you enter the United States on a student (F-1) visa, you will usually be admitted for the duration of your student status (often abbreviated in your passport or on your I-94 card as "D/S"). That means you may stay as long as you are a full time student, even if the F-1 visa in your passport expires while you are in America. If you were not admitted for the duration of your student status and want to renew your F-1 visa you will need to provide: - A passport valid for at least six months - Form DS-156, together with a Form DS-158. Some applicants will also be required to complete and sign Form DS-157. Blank forms are available without charge at all U.S. consular offices and on the Visa Services website under Visa Applications Forms - A receipt for visa processing fee. - A new I-20 or an I-20 that has been endorsed on the back by a school official within the past 12 months, stating your new length of studies.
