1.1 A company compares two temperature instruments daily: one coupled to a processor computer and the other used for visual control. Day-to-day variation is expected. On each of three days, the two instruments are used to measure the temperature. Ideally, these two instruments should agree. How many factors are there in this experiment? What are they? List the levels for each factor.

Question 1: Sally's pet lizard makes a weird groaning noise every couple of seconds. She notices that the number of groans per minute is very regular, but increases as the temperature increases. Further observations reveal that the number of groans per minute actually has a linear relationship with temperature over the normal range of temperatures in the lizard's natural environment. So she decides to make use of her lizard as a thermometer. Sally measures that the number of groans per minute at 10.0°C is 12, and the number of groans per minute at 45.0°C is 31. If she measures that the number of groans per minute in the lizard's usual aquarium is 24, what is the temperature in the aquarium, in degrees Celcius? You can check your answer using the Mastering Physics assignment. Math tip: A linear relationship between two quantities X and Y, means that for a change in X (which we usually call AX), the change in Y is given by AY = m AX, where m is some constant. In the range of X where this…

1. To determine the dynamic viscosity of a liquid you take repeated measurements of the liquid density and kinematic viscosity. These data are summarized in the following table: Avg. measurement Total Uncertainty P 999 kg/m³ ±0.5% V 1.23 mm²/s ±0.01 mm²/s kg Ns What is the dynamic viscosity? Give dynamic viscosity in units of; which is the same as ms 2. Determine the absolute and relative uncertainties in the dynamic viscosity.

Using the value of 0.55s ± 0.17s calculate the value for g and the value for uncertainty in g. Using the formula provided in image.
