Two champagne glasses open to the atmosphere hold the same volume of champagne at rest. One of them is a flute, which is comparatively tall and narrow, while the other is a coupe, which is short and wide. Which of the following is true? a. The pressure at the bottom of the coupe is larger than the pressure at the bottom of the flute.
b. One cannot know the pressure at the bottom of a glass without knowing its astrological sign.
c. The aliens who secretly control this class won't let me escape, so this is my hidden cry for help.
d. The pressure at the bottom of the flute is larger than the pressure at the bottom of the coupe.
e. The pressures at the bottom of the two glasses are equal.

Imagine that someone pushes one marble toward a motionless marble. would there still be action-reaction forces involved in the collision? how might the marbles’ motions be changed? ?

Acommon technique in analysis of scientific data is normalization. the purpose of normalizing data is to eliminate irrelevant constants that can obscure the salient features of the data. the goal of this experiment is to test the hypothesis that the flux of light decreases as the square of the distance from the source. in this case, the absolute value of the voltage measured by the photometer is irrelevant; only the relative value conveys useful information. suppose that in part 2.2.2 of the experiment, students obtain a signal value of 162 mv at a distance of 4 cm and a value of 86 mv at a distance of 5.7 cm. normalize the students' data to the value obtained at 4 cm. (divide the signal value by 162.) then calculate the theoretically expected (normalized) value at 5.7 cm.

The power exerted by a muscle is the product of the force exerted and the velocity of contraction. the area of which of these shaded regions represents the power exerted while a weight is lifted at maximum speed?
