WILL RATE YOU!!!

Suppose you wanted to hang a frame imaged on the wall. The object will be hanging by two strings. Both of the strings attached are at the top of the framed imaged. The second string angel is 142 degrees (counter-clockwise from right) and the first string angel is 52 degrees (counterclockwise from right) and the tension is 48 N.

-Make a force diagram. What could be the tension in the second string?

-What must be the mass of the object hanging?

A real object is imaged by a thin lens (F=48mm). The image is located 300 mm from the object in air. Determine the possible locations of the lens. Determine the magnification and whether the image is upright or inverted and magnified or minified. What is the longest focal length lens that would produce 300 mm separation between the object and the image?

Physics Hang Glider You are flying a hang glider at 14 mph in the northeast direction (45°). The wind is blowing at 4 mph from due north. a) What is your airspeed? b) What angle (direction) are you flying? c) The wind increases to 14 mph from the north. Now what is your airspeed and what direction are you flying? If your destination is to the northeast, how would you change your speed or direction so you might make it...

Suppose an object is 4 sided marked as {1,2,3,.., 4. Now you toss this object 4 times. Let nS be the number of outcomes in this sample space. Let A be the event consisting of all outcomes in which 2 occurs at least once. How many outcomes are there in A? It is whole number. Computer follows comma rule when entering large numbers. For example, 1123 is entered as 1,123

Suppose that you as a researcher wanted to examine the impact of police officer rank on perceptions of friendliness by citizens in College Park, MD. Rank is measured as patrol officer, sergeant or captain, and citizen perception is captured by a scale ranging from -50 to 50 and measured in a survey given to 1,000 randomly selected people after an interaction with a police officer. 500 people talked to a patrol officer, 300 talked to a sergeant and 200 people...

Consider a “system with two lenses in tandem”. Suppose that you have an object that is located P1to the left of a lens with F1 focal length. Then suppose that you have a second lens with F2 focal length, and you place this lens D downstream of the first lens. Let us say that the final image of the optical system forms Q2 past the second lens. The two lenses are one after another, or in tandem. (a) Draw a...

You have a massless, ideal spring with an unknown spring constant ?. You hang the spring from the ceiling. You then attach a mass (? = 21.0 kg) to the spring, which causes it to fall a distance of 2.75 m before stopping immediately before hitting the floor. (a) What is ?? (b) Graph gravitational potential energy versus the position of the mass above the floor. (c) Graph elastic potential energy versus the position of the mass above the floor....

7) Suppose you wanted to test to see if the population mean of cotinine levels in the 40 smokers from question 6 (SEE BELOW FOR QUESTION 6) is equal to 225 ng/ml. Using the confidence interval method what would your decision be using: (3 pts) a) A 90% confidence interval estimate of the mean cotinine level of all smokers. b) A 98% confidence interval estimate of the mean cotinine level of all smokers. c) A 92% confidence interval estimate of...

3) Suppose you wanted to simulate possible profit outcomes, and you know that revenues have a 30% likelihood of being $2 million, 12% likelihood of being $3.5 million, 48% likelihood of being $4 million, and 10% likelihood of being $4.5 million. Furthermore, Costs have a 30% probability of being $3.25 million and a 70% probability of being $3.5 million. Using Excel, simulate 100 instances of profit. Calculate average, minimum, and maximum profits. Is 100 instances sufficient? Why or why not?

1. a) An apple weighs 1.12 N . When you hang it from the end of a long spring of force constant 1.57 N/m and negligible mass, it bounces up and down in SHM. If you stop the bouncing and let the apple swing from side to side through a small angle, the frequency of this simple pendulum is half the bounce frequency. (Because the angle is small, the back and forth swings do not cause any appreciable change in...
