The basic function of an automobile's carburetor is to atomize the gasoline and mix it
with air to promote rapid combustion. Assume that 40 cm? of gasoline is atomized
into N spherical droplets. Each droplet has a radius of 2.0 x 10-5 m. Find the total
surface area of these N spherical droplets.
In determining the volume of an irregular shaped object with a graduated cylinder, any air bubbles sticking to the surface of the object when it is submerged cause systematic errors. Will this error give a density that is too high or too low?
Assume we had accidentally submerged our cube in such a fashion that cube lightly touches the bottom surface of the beaker. Which of the following describes the effect of this poor experimental technique?
a.
The apparent mass is too small and the calculated density is now too large.
b.
The apparent mass is too large and the calculated density is now too small.
c.
The apparent mass is too small and the calculated density is now too large.
d.
