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? Please read carefully.
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.

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s

i think its c if i'm wrong

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.

in order to follow the instructions and complete the statements, i need to use data from table c of your student guide. can you think of a way to let me see your student guide for a while ? i can't answer the question without the data in table c.
