How many multiple choice question do you have to get right to pass the NYS Living Environment Regent?
On most LE regents exams, there are between 41 and 43 multiple choice questions (in the first 2 sections). A has 30, and B-1 has 11-13. If you get 41-43 correct, your score ranges from a 66-69, so yes, technically, you can pass form just multiple choice, but don't risk it.
If I mark all answers 'C' in an MCQ (Multiple Choice Questions) exam, what is the probability of passing the exam?
This question touches on the over-all strategy of “testmanship,” which applies a generic answer strategy in addition to whatever knowledge of the subject matter you actually have.This assumes the MCQ you face is relevant to some course of study you are involved with, or some area of knowledge with which you have a working familiarity -but no special expertise.Here’s the over-all approach:Before you start answering, scan the whole test to get an indication of the questioning strategy. Do not assume you must answer the questions in order -unless that’s a test condition.Go ahead and answer the questions where you have a good degree of confidence that you know the answer. Those are your “gimmies.” Let us say that this gives you 25% of the test.Now scan the questions for choices which you know or strongly suspect to be wrong. The more questions with wrong answers, the better, because your actual odds of a correct answer will be between the “possible” answers. If you’ve narrowed it down to two, then your odds on a sheer guess or coin flip are 50–50. Let us suppose that such questions account for half of the test. If so, you pick up another 25% or thereabouts. But don’t guess randomly -make an effort to determine which choice is more probably correct. That give you a slight edge.That leaves 25% of the test which have few or no known wrong answers. In a 4 choice test, your odds on a guess are 25%. Again, use what you DO know to get an edge.Watch out for answers such as “neither A nor D” or “Both C and B.” Hit the BOTH answers first, for any question where you have ruled out at least one answer.Be aware that the wording of some questions may give you a strong clue as to the answer to a subsequent question.Ignore suspicious patterns to answers, such as “all the answers are “B.”In general, apply the above instructions in the order they are given. The idea is to grab the low-hanging fruit first, then work your way up the “tree,” to more difficult material.This website: General knowledge quizzes has many MCQ’s in various areas where you may practice. In a general knowledge test I just took, I scored 9 out of 10 correct, using the strategies above. There were 2 questions which included known wrong answers, improving my odds on a “guess.” There were 2 on which I was completely clueless.Bottom line: some knowledge of subject matter is essential, but knowing how to take the test can be critical.Hope that helps.
PHYSICS LAST QUESTION NEED HELP DUE TODAY!?
I'll help with c C is mgh which is mass * gravity * height, it's the formula for potential energy which is how much energy that object has at a specific height so you would do .14 * 9.8(gravity on earth) * 3.5 which is the height
Can anyone solve this PHYSICS question?? please?!?!?
Vf^2 = Vo^2 + 2ax where Vf = terminal velocity (here 0) Vo = initial velocity (here 110 km/h) a = max acceleration = -3.0 x 10^2 m/s^2 x = barrier thickness (solve for this first) reflection of equation Vo^2 + 2ax = Vf^2 subtraction of Vo^2 from each side 2ax = Vf^2 - Vo^2 and division by 2a x = (Vf^2-Vo^2)/2a now just plug numbers in AFTER changing the units to mks on Vo: Vo = 110 km/h * 1000m/km * 1h/3600s = 30.6 m/s V0^2 = 934 m^2/s^2 so x = (0 m^2/s^2 - 934m^2/s^2)/(2*(-3.0 x 10^2m/s^2)) = 1.56 m (after unit cancellation) but with the number of significant digits used in your problem (2), x = 1.6 m
I need to know how many regents does a student need to pass to get a regular high school diploma?
Regents is this big city test in New York....and I've been told there's an amount of regents a student need to get a local diploma, a regents diploma or a advanced diploma.....but so far I'm going for the local because i didn't pass that much regents....so i really need to know how many regents i have to pass to get a local diploma, because right now i just want to get out of high school, it don't really matter to me what kind of diploma i have....
What did you think of the 2011 Physics Regents?
thought it was rly easy. electron positron one you had to use e=mc^2. electrostatic force is 2f in opposite direction bcuz the charge was 2 times bigger and if you just look at the equation for electrostatic force it is directly related to charge. angle for last question was the angle to the normal whatever that was. and the lines should have been firther apart in the box bcuz if the speed decreases the wavelength increases.
Do significant figures matter on the AP Physics exams?
Yes and no. Yes, in that you may lose some points if you don't put the correct number of significant figures. No, in that if you do, it won't be many points. It's more important to show your work and what led to your answer. From the AP Physics B Scoring Guidelines: "Strict rules regarding significant digits are usually not applied to numerical answers. However, in some cases answers containing too many digits may be penalized. In general, two to four significant digits are acceptable. Numerical answers that differ from the published answer due to differences in rounding throughout the question typically earn full credit. Exceptions to these guidelines usually occur when rounding makes a difference in obtaining a reasonable answer. For example, suppose a solution requires subtracting two numbers that should have five significant figures and that differ starting with the fourth digit (e.g., 20.295 and 20.278). Rounding to three digits will lose the accuracy required to determine the difference in the numbers, and some credit may be lost."
Hey can you do my High School Physics homework?
My Physics teacher has out done himself, he managed to make ABSOLUTELY NO SENSE TO ME, usually I get what he's talking about through his THICK Greek accent but this time.. Anyway I need to do this homework so yeah could you do it and then explain why so maybe I'll understand? (4 Questions, multiple choice, explain your answer) 1Which factor, when doubled would produce the greatest change in the magnitude of the centripetal force acting on the cart? A.Mass of the cart B.Radius of curvature of the path C. Velocity of the cart D. Weight of the cart 2. As the time taken for a car to make one lap around a circular track decreases, the centripetal acceleration of the car... A. Decreases B. Increases C. Remains the same 3. Which best describes the tangential acceleration of a cart moving at a constant speed in a horizontal circle? A. 0.0m/s^2 B. 9.8m/s^2 C. Constant and directed radially toward the center of the curvature D. Constant and directed radially away from the center of curvature 4.Which best describes the centripetal acceleration of a ball of mass m moving at constant speed v in a horizontal circular path or radius r? A. Zero B. Constant in direction, but changing in magnitude C. Constant in magnitude, but changing in direction D. Changing in both magnitude and direction My teacher demands explanations with each answer so he KNOWS you didn't copy from someone else so please explain (this will also help me understand it)
