1 answer:
TEA [102]2 years ago
8 0

Answer:

Friction, normal force, and weight

Explanation:

If the book slows down, it means that there must be friction acting in the opposite direction of the direction the book is moving in.

Weight is caused by the gravitational pull of the Earth on the book, and normal force is the table pushing the book up because the book is pushing down on the table (3rd law.)

Note that weight and normal force is not the 3rd law action-reaction pair. The pair is the force of the book on the table and the force of the table on the book.

Mila [183]

Answer:

The blue light

Explanation:

Spectrums of visible light with longer wavelength are absorbed more quickly such as red than those with shorter wavelength. This contributes to why blue with higher energy and shorter wavelength is able to penetrate deeply compared to others that are easily absorbed. Blue light persist longer so it reaches the depth first while so of others are absorbed.

What is the rate at which an object moves but doesn't include direction?
Juli2301 [7.4K]
Great question !

The rate at which an object covers distance, without worrying
about the direction it's moving, is the object's SPEED .

When the direction is also given, then you have the object's VELOCITY.


This question is important.  It gives us a chance to point out that
"velocity" is not just a fancy word for speed that you use when you
want to sound smart.  There's actually an important difference between
'speed' and 'velocity'.
