What kind of substance has particles that are close together but can change shape depending on its container?
a. solid
b. plasma
c. liquid
d. gas

The correct answer is going the be liquid.

Just like any substance, water can exist in three different forms, called states: solid, liquid and gas. The state will change when the substance is heated. ... As a liquid, a substance has a fixed volume, but its shape changes to fill the shape of its container.

probably not if net force is zero

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
