Consider the model of three states of matter. this is an example of a conceptual model. what does this model illustrate about these three states of matter? all but one could apply. a) the particles in a solid are arranged in a definite shape. b) the three states of matter are composed of individual atoms. c) the particles of a gas have have enough kinetic energy to escape from an uncovered container. d) the arrangement of particles in the three states of matter are related to the energy of those particles. e

this is poiselle's equation from fluid mechanic in physics. mech eng

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
