In what way would readings from a digital thermometer be preferable to those from a liquid-based thermometer?

A digital thermometer is more preferable than a liquid-based thermometer because it gives accurate data than the liquid thermometer. Liquid thermometer is affected by the temperature, and when it does, the liquid expands and so des the material covering the thermometer. For the digital thermometer, it has less error because it already has a sensor inside it that determines the temperature of the substance.

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
