Air mass abbreviated Cp has cold temperature and dry moisture.
Explanation:
Air mass abbreviated Cp means regions of continental polar or continental arctic. So mostly in the northern hemisphere where the temperature is very low like in Alaska, the mass of air is termed as Cp. At those low temperature, the temperature is very cold and so the moisture present in the air in those regions will be dry in nature. Mostly, they originate in the northern hemisphere like in canada, Alaska and then they will spread toward the south and east directions.
So they air masses present in those cooler regions are extremely cold and has dry moisture.
Answer:
The angle between the red and blue light inside the glass is 1.9°.
Explanation:
Given that,
Refractive index
For blue = 1.64
For red = 1.54
Incident angle = 48°
We need to calculate the angle between the red and blue light inside the glass
Using Snell's law
For blue ray,
For red ray,
We need to calculate the angle between the red and blue
Put the value into the formula
Hence, The angle between the red and blue light inside the glass is 1.9°.
Answer:
The speed of the bag just before it reaches the ground is 21.71 m/s.
Explanation:
The speed of the bag can be found using the following equation:
Where:
is the final speed =?
is the initial speed = 7.7 m/s
g: is the gravity = 9.81 m/s²
y: is the height = 21 m
Therefore, the speed of the bag just before it reaches the ground is 21.71 m/s.
I hope it helps you!
Answer:
100 m displacement east and total distance of 300 m
Explanation: Let's break this down, if the sprinter runs 200 meters west, then 100 meters east, than her displacement would be 100 meters east, since that deviates from her initial direction. Her total distance is the 200 meters west plus 100 meters east
