In question #5, the one where you have to label the three pictures,
all of your labels are correct !

Look at the 3rd picture, where the light is coming down slanted,
hitting some kind of surface, and bouncing away slanted.
You labelled that picture "reflection", and that's correct.

Now, look at the two angles marked in the picture .... the angle
between the arriving light and the surface, and the angle between
the departing light and the surface.

There is a statement in Science called the "Law of Reflection".
It simply says that those two angles are EQUAL.
I don't think we have to get into WHY right now.  I think that
at this point, your class is just trying to teach you what the law says. 
If you go on and study more physics in High School, then you'll learn
WHY the angles are equal.

If the light ray arrives and hits the mirror at a 40° angle,
then it'll leave the mirror at a 40° angle.  It's that simple.

The two angles are the ones marked equal in the picture
where you wrote 'reflection'.

What happens if you reverse the orientation of the permanent magnet? why?
belka [17]
If one reverse the orientation of a permanent magnet ITS MAGNETIZATION WILL BE PERMANENTLY REVERSED. This is because, the magnetic domains inside the permanent magnet aligned with the new applied field and increase with it while those domains that are anti aligned with that field will shrink.

A manufacturer supplies plastic cups that are placed under the legs of the chair
777dan777 [17]

A manufacturer supplies plastic cups that are placed under the legs of the chair. The manufacturer's claim is that there will be no marks of chair due to pushing or pulling on the floor.

<h3>Who is a manufacturer?</h3>

A manufacturer is a person who converts his idea of developing and constructing any item using some set of machines.

A manufacturer supplies plastic cups that are placed under the legs of the chair.

When there is a relative motion between two objects, friction force causes the opposition to this motion. Between chair and floor, there will be high magnitude of force. But if we insert plastic cups in the legs of chair, then the friction between cup and floor will be less. This keeps the floor protected form any scratches.

Learn more about manufacturer.

sasho [114]
<h2>The different forces acting on the ball while its in air</h2>

Amy throws a softball through the air. Applied, drag and gravitational forces are acting on the ball while it’s in the air. The softball experiences force as a result of Amy’s throw. As the ball moves, it experiences from the air it passes through.

It also experiences a downward pull because earth has the property to attract everything which is on the earth towards it. The ball is moving in the air but earth applies force on the ball to get back on the ground. Hence, in this way, gravitational force applies.

There is also a drag force which results due to friction that is present in the air. It resist to move ball in the air and there will also be applied force which is given by a person who throws by applying force.

A baseball has a momentum of 6.0 kg.m/s south and mass of 0.15kg. What’s the baseballs velocity?
Mashcka [7]

Answer:

<em>v=40 m/s south</em>

Explanation:

<u>Momentum </u>

It's a physical magnitude that measures the product of the mass by the velocity of a particle. Its units in the International System is kg.m/s and the formula is

p=m.v

Where m is the mass and v the velocity of the particle. If we wanted to solve for v, we have

\displaystyle v=\frac{p}{m}

The baseball has a momentum of 6.0 kg.m/s south and mass of 0.15kg, thus

\displaystyle v=\frac{6}{0.15}=40\ m/s

The velocity is directed to the south
