<span>Condensation is the change of
the substance from liquid to solid phase. Example of this is the formation of
ice. Vaporization is the change of substance from liquid to gas phase. Example of
this is the boiling of water. Deposition is the change of a substance from gas
to solid phase. Example of this is the formation of ice on a winter day. Sublimation
is the change of a substance from solid to gas phase. Example of this is dry
ice. The answer is letter C.</span>
Answer:The place to go for the answer to such an easy question is the SI Brochure, the document which defines the SI and all its units.
Answer:
v = 1.98 mph
Explanation:
Given that,
Speed to travel one mile is 100 mph
Speed to travel another mile is 1 mph
The formula used to find your average speed is given by :

Putting the values, we get :

v = 1.98 mph
So, yours average speed is 1.98 mph.
Answer:
Concentrating solar power (CSP) plants use mirrors to concentrate the sun's energy to drive traditional steam turbines or engines that create electricity.
Explanation:
The correct answer is
<span>c. one person exerts more force than the other so that the forces are unbalanced.
In fact, the door is initially at rest. In order to move the door, a net force different from zero should be applied, according to Newton's second law:
</span>

<span>where the term on the left is the resultant of the forces acting on the door, m is the door mass and a its acceleration.
In order to move the door, the acceleration must be different from zero. But this means that the resultant of the forces acting on it must be different from zero: this is possible only if the forces applied by the two persons are unbalanced, i.e. one person exerts more force than the other.</span>
