Your friend says that the mass of any object is distributed symmetrically around its center of mass. Design an experiment to test your friend's idea. You have a meter stick, a set of small objects of different masses, masking tape, and a mass measuring scale. Describe your experiment and predict the outcome based on your friend's idea.

C. leas t del Niu 3. Three students make measurements (in m) of the length of a rod using a meter stick. Each student's measurements are tabulated in the table below. Using your calculator in statistic mode calculate the mean L, standard deviation S and uncertainty u of the measurements. Student L1 L3 L2 1.4711 L4 1.4715 SD u Student 1 1.4717 1.4722 1,4716 t.4754 1.4710 1.4753 1.4759 1.4756 1.4749 Student 2 Student 3 1.4719 1.4723 1.4705 1.4719 Note that the actual length of the rod is determined by a laser measurement technique to be 1.4715 m (this should be considered the standard value). a) State how one determines the accuracy of a measurement. Apply your idea to the measurements of the three students above and state which student has the most accurate measurement.

2. In each measurement below, write your reading with the proper number of significant figures and uncertainty and draw the corresponding pdf. Always include units for physics quantities.

Please do help me in this mathematics of measurement subjec please. I promise to give a good feedback and perfect score.. Please i badly need it in 1 hour from now.

Direction: Analyze the diagram below. Solve for the unknown value.  note: please explain your answer thoroughly and do not forget to include the solution. thank you!

please follow instruction do not do it other way follow guess method only please    Solving problems in Physics, we must always use GUESS method.Guess stands for: Guess: G Here you write down what is given in the questionUnknown: U Here you list what you have to calculate, to solve for.Equations: E here you list all the formulas you need to use to solve the problemSubstitution: S This first letter S in the word, you will just substitute what is given in theformula. You do not calculate anything. The calculations will occur at the second S: Solve. Whatis very important here is to carry with you the units of measure in the formula. Not only thenumbers. This is very important, once again.Solve: S The last step, second S, you will solve what you plugged in the first S for Substitution.Very important here is to manipulate the units of measure such that the final units of measureto be proved by your work. This part is very important, since you will allow you to verify thatwhat you do is…
