What the motion of an object that has an acceleration of 0 m/s
Degger [83]
<span>Everything in the system is stable and therefore the objects motion is stable. That is to say it is not changing what it is already doing. As far as i know zero times zero is still zero. In that case then the motion must be constant or stable.</span>

Which describes the type of image formed by a plane mirror?
guajiro [1.7K]

Answer:

It is a copy of an object and appears to be coming from behind the mirror.

Explanation:

  1. The plane mirror has a flat surface, where of its surface is polished to reflect the light.
  2. The plane mirror shows the image as the same size of the object.
  3. The image produced by the plane mirror is virtual and erect.
  4. But the orientation of the image formed changes the left and right.
  5. Hence,the image appears to be coming from behind the mirror.

A 13.3 kg box sliding across the ground
adelina 88 [10]

Answer:

<em>0.25</em>

Explanation:

According to newtons law of motion

\sum F_x = ma

F_f =  ma

nR = ma

nmg = ma

ng = a

n = a/g

g is the acceleration due to gravity

Given

a = 2.42m/s²

g = 9.8m/s²

Substitute into the formula;

n = 2.42/9.8

n = 0.25

<em>Hence the coefficient of kinetic friction is 0.25</em>

Len [333]

The process of digestion breaks down proteins into smaller molecules that are used to rebuild other proteins. During digestion, proteins undergo chemical changes.

<u>Option: D</u>

<u>Explanation:</u>

Proteins are broken down into amino acids considered the foundational element. When issued, these tiny molecules can then be consumed into the bloodstream via the gut wall. An enzyme is a protein which can regulate biochemical response rate. An enzyme integrates a water molecule around the bond in enzymatic hydrolysis processes which allows it to split.

The bonds which hold together the amino acids are recognized as peptide bonds. A hydrolysis process comparable to that included in splitting up carbohydrates is required to break the peptide bonds within a protein. Enzymes identified as proteases are required for the protein to disintegrate.
