No. The companion is wrong.
You are shivering because, since it's cold outside, your body is becoming incapable of maintaining the the same temperature outside ad well as inside.
So, in order to compensate, your body uses mechanism of shivering in order to produce more heat by constricting the blood flow in vessels.
Therefore, you shiver from cold.
The isobars in the conventional series that will be needed

To add, an isobar is <span>a line on a map connecting points having the

I'm not too sure since the graduated cylinder was missing and I really don't know how to do it then. But give this a shot. Are you sure it wasn't a graduated cylinder, because I have no idea what that means
Answer:
a= - 6.667 m/s²
Explanation:
Given that
The initial speed of the box ,u= 20 m/s
The final speed of the box ,v= 0 m/s
The distance cover by box ,s= 30 m
Lets take the acceleration of the box = a
We know that
v²= u ² + 2 a s
Now by putting the values in the above equation we get
0²=20² + 2 a x 30

a= - 6.667 m/s²
Negative sign indicates that velocity and acceleration are in opposite direction.
Therefore the acceleration of the box will be - 6.667 m/s² .
