Answer:
A model rocket is launched with an initial upward velocity of 215 ft/s.
Explanation:
Volcanoes that produce explosive eruptions tend to have thicker, more viscous magma, and a greater volume of gas. <span>Different types of volcanoes tend to produce different types of eruptions. Shield volcanoes, those with broad, gentle slopes, produce the quietest eruptions. The main difference is the shape of the volcano.

Explanation:
It is given that,
Distance, r = 3.5 m
Electric field due to an infinite wall of charges, E = 125 N/C
We need to find the electric field 1.5 meters from the wall, r' = 1.5 m. Let it is equal to E'. For an infinite wall of charge the electric field is given by :
It is clear that the electric field is inversely proportional to the distance. So,
E' = 291.67 N/C
So, the magnitude of the electric field 1.5 meters from the wall is 291.67 N/C. Hence, this is the required solution.
Answer:
Polar areas
Explanation:
From what I know Arctic, Antarctic, and polar air masses are cold. Polar (cold), Arctic (very cold), Equatorial (warm and very moist), and Tropical (warm).
- With the options you gave, you can immeditaly elimate 1. tropical areas and 2. an area where its summertime.
- Your then left with two options 1. an area where its wintertime and 2. polar areas
I then concluded that cold air masses tend to originate from POLAR AREAS.
