Answer:
1. Nitrogen
2. Oxygen
3. Carbon dioxide
4. Water vapor
5. Ozone
Explanation:
The atmosphere composes of 78% nitrogen which occupies the largest percentage followed by oxygen which takes up 21%, Argon takes up 1% then other components such as water vapor occupy between 0-7% and ozone takes 0.0-0.01. Moreover, 0.01-0.1 is occupied by carbon dioxide. Therefore, the answers for 1-5 are as follows.
1. Nitrogen
2. Oxygen
3. Carbon dioxide
4. Water vapor
5. Ozone
Answer:
Acceleration of the plane, a = 5.4 g
Explanation:
It is given that,
Speed of the jet plane, v = 1890 km/h = 525 m/s
Radius of the arc, r = 5.20 km = 5200 m
The plane is moving in the circular path, the centripetal acceleration will act on it. It is given by :
We know that, the value of g is,
So, the acceleration of the plane is 5.4 g. Hence, this is the required solution.
Answer:
Explanation:
given data= 34.2 m/s
we have to convert it into km/s
as we know that
1 km=1000 m
so 1 m= 1/1000 =0.001 km
now we know that 1 min=60 sec
so 1 sec=1/60= 0.016 min
therefore
34.2m/s = 34.2*m/sec =34.2*0.001 km /0.016 min
so 34.2 m/s =2.1 km/min
I believe it’s A, i could be wrong tho 3
