Describe at least two different objects that you think are
magnetic. Why do you think these objects are magnetic?

paper clips and scissors

Explanation:

Objects are made of atoms. However, in case of magnetic objects like the "paper clips" and "scissors," their atoms' magnetic fields are said to be arranged in alignment with each other. So, this means that their north magnetic pole and south magnetic pole are aligned with each other. These makes the magnetic objects different from non-magnetic objects, whose north and south magnetic poles are placed randomly.

So, this explains the answer.

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
