Answer:
I1 = ε/R1
I2 = ε/R2
I3 = ε/R3
Explanation:
From the image, we see that the resistors are connected in parallel. This means that the voltage passing through them is the same.
Now, formula for current is; I = V/R
In this case, V which is voltage is denoted by ε.
Thus;
I1 = ε/R1
I2 = ε/R2
I3 = ε/R3
Carbon dioxide, nitrous oxide, methane and ozone are all greenhouse gases.
D. Advances in technology were needed to gather more evidence.
Explanation:
New technologies had to be developed to ascertain Wegener's claims.
The major flaw in Wegener's postulate was that the moving continents lacked a mechanism to drive them into motion.
His theory needed more scientific backing also.
- A major leap was made when new technologies used during the second world war was deployed to investigate the ocean floor.
- Sequences of magnetic anomalies were unraveled using equipment developed during the second world war
- This gave further proof to the idea of continental drift and it expanded the theory into a more broader and inclusive theory of plate tectonics.
