The existence of atmosphere increases the average planetary temperature by more than 15°C, due to the greenhouse effect of some atmospheric compounds. The most important of them are water vapour (H2O), ozone (O3), carbon dioxide (CO2), and methane (CH4).
Answer:
Velocity of the passenger = 78.8[km/h]
Explanation:
In order to solve this problem, we must observe the train from a distant point of the train. In this way we can observe that the train moves at 80[km/h] relative to the ground.
In such a way that the passenger moves in a direction contrary to the movement of the train.
![v_{pass}=80-1.2\\ v_{pass}=78.8[km/h]](https://tex.z-dn.net/?f=v_%7Bpass%7D%3D80-1.2%5C%5C%20v_%7Bpass%7D%3D78.8%5Bkm%2Fh%5D)
The Observer located outside the train will see how the passenger moves away at 78.8 [km / h] and not at 80[km/h] which is the speed of the train.
Answer:

Explanation:
Potential across the electrochemical cell, V = 2 V
Current, I = 1 A
Time, t = 1000 s
Let n electrons move from the anode to the cathode. We know that electric current is calculated as :

Also, q = ne




So,
electrons move from the anode to the cathode in 1000 seconds.
Answer:
360
Explanation:
just add a 0 when using dm
The 1st one is basically B because it will stay in motion with the same speed and in the same direction unless acted on by an unbalanced force and the 2cd one is A because most of is transformed into thermos energy. hope this helps!
