The soft iron is a magnetic material hence it became an induced magnet and attracted the blade.
<h3>What is a magnetic substance?</h3>
The term magnetic substances is a substance that can be attracted b a magnet. Now we know that the soft iron is a magnetic material hence it became an induced magnet and attracted the blade.
Recall that a magnetic substance is a substance that can be attracted by a magnet. Wood can not be attracted by a magnet but soft iron cash attracted by a magnet hence it is a magnetic substance.
This is not possible in the case of the wooden block since it is not magnetic as such the the razor blade on the wooden block was attracted to the magnet while the other on the soft iron was not.

Answer:
0.42 meters/second
Explanation:
The total distance traveled by Mary is: 80 m + 125 m + 45 m = 250 m
We want the speed in meters/second, so we have to convert the 10 minutes elapsed during the trip into seconds. Then we need a conversion factor, 1 minute is equivalent to 60 seconds.
time = 10 minutes * (60 seconds/1 minute) = 600 seconds (notice that minute is cancelled because is multiplying and dividing)
Now, we can compute the average speed is as follows:
Average speed = total distance/time = 250 m/600 s = 0.42 m/s
Because specular reflection occurs with a mirror, while diffuse reflection occurs with aluminium or iron plate
Explanation:
Reflection is a phenomenon typical of waves (such as light wave), that occurs when a wave bounces off the surface of a certain material, going back into the original medium at a certain angle, without changing speed, frequency or wavelength.
The direction of the reflected ray is given by the law of reflection, which states that:
- The incoming ray, the reflected ray and the normal to the surface all lie on the same plane
- The angle of incidence is equal to the angle of reflection
Depending on the type of surface, two different types of reflection can occur:
- Specular reflection: this occurs when the surface is perfectly smooth. In such a case, all the incoming rays of light hit the surface with same angle of incidence, therefore they are reflected at the same angle. This means that a perfect and clear image of the original object can be formed: this is the case of a mirror.
- Diffuse reflection: when the surface is not smooth, the imperfections on the surface are such that the incoming rays of light hit the surface at different angles of incidence. As a result, the rays are reflected at different angles to each other, and therefore no clear image of the object is produced. This is the case of aluminium or iron plate.
