1. You are asked to find the weight of a paper clip as accurately as possible and given ten paper clips and a scale that has a precision of 0.1 g. (A paper clip weighs about 1 g.) Which of the following proceedures would give you the most precise measurement the weight of a paper clip?
Weigh each paper clip individually, average the values and calculate the standard error.
or
Place all ten paper clips on the scale at once, then divide the value and the precision of the scale by ten.
EXPLAIN WHY!
Homework Answers
Place all ten paper clips on the scale at once, then divide the
value and the precision of the scale by ten
this way max error in each weight of paper clip = 0.1/10 = 0.01
gm
if we measure them indivisually possible error each time = 0.1
gm

1. What do volumetric glassware measure? What types of volumetric glassware will you be using in this experiment? 2. What is density? How is it calculated? 3.Define meniscus. State how you use the meniscus in making volumetric measurements. Draw a sketch of a meniscus for water in a graduated cylinder. 4. Define accuracy and precision. Explain what the “reliability of a measurement” means. (These concepts can be found in Chapter 1 of your text.) 5. Why will you calculate accurate...

It is possible, using basic lab equipment, to observe the force that a magnet exerts on current in a wire. Equipment:DC Power Supply (3A preferred), Long Banana wire, Large Pasco C Magnet, 1 gm sensitivity food scale. (There will only be a few systems set up. Your TA's will direct you in sharing their use.) Theory: The force due to a magnetic field on a straight wire carrying a current in a uniform B field is: F = iL x...

4. Suppose that a student performed the experiment and calculations perfectly as directed except that, unknown to the student, the balance was not zeroed but weighed 0.100 g too high throughout the experiment. Would the calculated val- ue for the density of the unknown liquid be correct? That is, would it be equal to, higher than, or lower than the true value.

Lindsay Smyth, a 15 year old young woman, was admitted by her pediatrician for evaluation. Her parents, who are divorced, came with her to the hospital. The client lives with her mother and has no siblings. She has no past psychiatric history or other medical problems. Her pediatrician and her parents report that the client has lost 40lbs in the past year. Despite this weight loss, she has continued to go to school and to excel academically. She also jogs...
