If we had only a ruler and a clock as measuring devices, how could we measure the density of water?
Homework Answers
We simply can't. To measure the density you need to measure the mass and the volume. Now, ruler measures length and clock measures time. So, we can't measure the density.
We must need a balance and a marked flask to measure the density.

Instructions:
For this lab, you need a metric ruler or a metric measuring
tape. If you don’t have either, you can print one from the
internet, or download a ruler app on your phone. You also need
something relatively small and rectangular(something that is easy
to find at home). Some ideas: large rectangular eraser, box, book,
a loaf of bread, a Tupperware container, a binder, etc. If the
object is not exactly rectangular, estimated average
dimensions.

Four workers measure four different shafts with three different measuring devices. The measurements are 4.8 in, 4.75 in, 4.76 in and 4.764 in. a. Use the appropriate round-off rules to find the sum of the measurements b. Apply the maximum error to each measurement to find the minimum possible sum and the maximum possible sum. Does your answer from (a) lie between them?

We want to measure the perimeter of a rectangle ABCD. The error made in measuring the sides AB and CD has standard deviation 3cm. The error made in measuring the sides BC and AD has standard deviation 2cm. Assume that the errors made in measuring the four sides are independent random variables. (a) What is the standard deviation for the error of measurement of the perimeter of the rectangle if we measure sides AB and BC and multiply the sum...

Measuring distances to high precision is a critical goal in
engineering. Numerous devices to exist to perform such
measurements, with many involving laser light. Shining light
through a double slit will provide such a ruler if (1) the
wavelength of the light beam and slit separation is known and (2)
the distance the minima/maxima appearing on the screen can be
measured. But this in itself requires a physical measurement of
distance on the object, which may not be practical. In...

Question 12: In this lab we ignored the contribution to torque of the ruler that has been moved off- center. In reality, the portion of the ruler to the right of the central pivot pulls down and provides a clockwise torque, while the portion of the ruler to the left of the central pivot provides a counter clockwise torque. Describe two ways you could calculate the contribution of the ruler to the torque. You may assume you have access to...
