A plant dying after being exposed to poison represents a physical change. True or false. (No links please.) Correct answers only..

False is the correct answer.

It is considered more of a chemical change because all of the cells inside the plant decompose (change chemicaly)

False

Explanation:

saw this on another question, it's because a flower that becomes a poisonous flower would be a chemical change. If it were to mix with the poison it would just become something new entirely.

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

amplitude

hope this
