You have a piece of metal of unknown origin and type. Provided you have the ability to measure the weight of the piece of metal both in air and in water (Wair, WH2O), and know the density of air and water (densityair,densitywater), determine the density and the specific gravity of the metal. Hint: draw a free body diagram for each fluid, and use Archimedes’ principle. Do not make any simplifying assumptions regarding density ratios -- until the end, when you...

Suppose you are to design a new porch light that has 3 modes of operation: OFF, ON continuously, and in the third mode it turns on and off based on its own motion detector. You desire to have this light work with existing house wiring. Describe two different ways that you could make the light work with an existing single-pole single-throw switch. Is one of your methods better than the other? Why? Note this can be done from a block...

(1.) Sample Lab-Based Question... In the physics laboratory you are given a metal block that is approximately the size of a brick. You are also given 2.0m long wood plank with a pulley* attached to the end of it. Your objective is to experimentally determine the coefficient of kinetic friction ( μ k ), between the metal block and wood plank. *Note: you do not necessarilly need to use the pulley. (a.) From the list below, select the additional equipment...

Determine the amount of torque that is needed to hold up a weight with the arm at shoulder level. Draw a free body diagram to represent it. Assume the following and show all work: Weight that is being held= 12 lbs Center of mass of the limb = 26 cm from shoulder joint Weight of limb= 8.5 lbs Angle of insertion of the deltoid is 15 degrees. Moment arm is 3 cm. Length of the limb = 65 cm Weight...

Show all work and diagrams necessary. Please make sure you show how you derive any equations you used!!! Which of the following statements best describes "free fall motion." Free fall motion describes any horizontal motion. Free fall motion is two dimensional motion. Free fall motion is a subset of projectile motion. Free fall motion is a subset of circular motion. A body can experience a static friction force in its direction of motion. True False If a normal force is...

Assume that you can impose a policy in a certain market that restricts how the firms will decide their output: simultaneously or sequentially. In this market there are only two identical firms, no threat of a new entry, and the output is homogenous. The market demand is d(p) = 300 - 6(p) and the firm’s marginal cost is MC = 5. You have to support your policy using quantitative results, not only your intuition (you will not get any credit...

You are on an amusement park ride with your back against the wall of a spinning vertical cylinder. The floor falls away and you are held up by static friction. Assume your mass is 80 kg. (a) Draw a free-body diagram of yourself. (Do this on paper. Your instructor may ask you to turn in this work.) (b) Use this diagram with Newton's laws to determine the force of friction on you. N (c) If the radius of the cylinder...

Male border collies tend to weight more than females. Can we use weight to predict whether a border collie is male or female? Suppose that the weights of fully-grown female border collies follow a normal distribution with mean 15 kilograms and SD 3 kilograms. Suppose also that the weights of fully-grown male border collies follow a normal distribution with mean 21 kilograms and SD 4 kilograms. Determine the probability that this prediction rule would mistakenly predict that a female border...
