Answer:
This change in quantity demanded is caused by a change in the demand price. It is illustrated by a movement along a given demand curve. In fact, the only way to induce a change in quantity demanded is with a change in the price.
Explanation:
Answer: B. Turning on your hazard lights.
Explanation:
Because...
that indicates the drive behind you to go in front of you and indicator lights that flash in unison to warn other drivers that the vehicle is a temporary obstruction.

Answer with Explanation:
Stress is defined as the force acting per unit area on a material.
Mathematically
where
is the stress , is an infinitesimal force that acts on an infinitesimal area
When a body is under stress it's dimensions change and this change in dimensions is known as strain.
Mathematically
where
strain in the object
is the change in any dimension of the body
Now in the above relation of stress, the area involved also changes when the body is loaded as the load produces strain which changes the dimensions of the body.
Now while calculating the stress if we use the original area of the cross section of the body prior to loading the stress that we calculate is the engineering stress and the strain associated with it is the engineering strain.
On the other hand if we use the true cross section of the body when it is loaded the stress that we calculate is the true stress and the strain associated with it is the true strain.
Mathematically they are related as
Thus the true stress is found to be larger than engineering stress.
Answer:
true
Explanation:
if it is not true it is false
