Answer:
the acceleration of A is three times that of B
A.
Polarized glasses allow vertical light in, blocking horizontal light so that most of the glare is eliminated.
The best conclusion that can be drawn is that D) A current does not flow in the wire
Answer:
a. mass density
Explanation:
<em>Land and sea breeze that occur near the shore are due to the variation of mass density of air with change in temperature.</em>
- When the air gets heated it becomes rarer in density and thus rises up in the atmosphere and its space is occupied by a cooler and denser air that flows to the place.
<em>During the day the land is warmer than the sea so the sea breeze blows and during the night the water bodies are warmer than the land so the land breeze blows.</em>
Both speed and velocity measures the distance traveled per unit time.
The difference between speed and velocity is that, speed is a scalar quantity which only has a magnitude and does not have a direction.
Velocity is a vector quantity and hence has both magnitude and direction.
In the 1st and 2nd case no direction is specified. So the answer is speed in these two cases.
In the 3rd and 4th case both magnitude and direction have been mentioned. Hence the answer is velocity in these two cases.
