Chapter 1, Problem Q1.4DQ
The U.S. National Institute of Standards and Technology (NIST) maintains several accurate copies of the international standard kilogram. Even after careful cleaning, these national standard kilograms are gaining mass at an average rate of about 1 μg/y (y = year) when compared every 10 years or so to the standard international kilogram. Does this apparent increase have any importance? Explain.

For about 10 years after the French Revolution, the French government attempted to base measures of time on multiples of ten: One
week consisted of 10 days, one day consisted of 10 hours, one hour consisted of 100 minutes, and one minute consisted of 100
seconds. What are the ratios of (a) the French decimal week to the standard week and (b) the French decimal second to the standard
second? Assume that the definition of a "day" remains the same.

A physicist needs to estimate the density of a cube (all sides of the cube have equal length). Density (in kg/m3)can be found by D = M L3 where M is the mass of the object (in kg) and L is the length of a side of the cube (in meters). Assume the mass M ∼ ·(µM = 1.0, σ2 M = 0.022 ) (i.e. 1.0±0.02) and assume the length L ∼ ·(µL = 0.1, σ2 L = 0.0052 ) (i.e. 0.1±0.005).Assume M and L are independent.(a) Approximate µD.(b) Approximate σD.(c) Write the estimate of the density, along with the estimated error, in engineering (i.e. ±) notation. Be sure tostate the units.

- In SI units, speeds are measured in meters per second (m/s). But, depending on where you live, you’re probably mole comfortable of thinking of speeds in terms of either kilometers per hour (km/h) or miles per hour (mi/h). In this problem, you will see that 1 m/s is roughly 4 km/h or 2 mi/h, which is handy to use when developing your physical Intuition.

Figure P1.6arrow_forwardThe SI units of mass density are kg/m3, but there are several other common units. One of the most commonly used units of mass density is gram per cubic centimeter, or g/cc. This is because pure water has a mass density of 1 g/cc. It turns out that 1 mL of liquid is equal to 1 cc of volume. So it is also possible to express the mass density of water as 1 g/mL. This makes water a useful tool since it is possible to use graduated cylinders to measure volumes.An object with a mass of 61.0 g displaces 785.0 ml of water when it is completely immersed.
