The answer is D. 3.33 A
In parallel connected devices, circuits are also placed parallel. It is known that in parallel circuits, total voltage is equal to the voltage of each device.
So, we know that:
Device 1 - R1 = 12 ohms
Device 2 - R2 = 4 ohms
Total voltage - V = 40V = V1 = V2
If V = I × R, for the first device is V1 = I1/R1.
⇒ I1 = V1 ÷ R1
⇒ I1 = 40 V ÷ 12 ohms
⇒ I1 = 3,33 A
<span>The ways for lessening the effect of increased carbon include reducing the components of the carbon footprint (the amount of carbon dioxide and other carbon compounds emitted due to the consumption of fossil fuels).</span> Air travel is one of the main components of the carbon footprint. <span>The solution for reducing the amount of carbon dioxide in the air is to burn fewer fossil fuels, but it is very difficult because the burning of fossil fuels is necessary for heating, electricity generation and transport.</span>
Power stations that burn fossil fuels to produce electricity are one of the main contributors of carbon dioxide in the atmosphere and the way to reduce it is to use less electricity which can be done by turning down the heating at home, insulating home, <span>using low-energy lamps etc.</span>
Answer: The vascular plants are set apart in two main ways: Vascular plants have vascular tissues, which circulate resources through the plant. This feature allows vascular plants to grow to a larger size than non-vascular plants, which lack these specialized conducting tissues and are therefore restricted to relatively small sizes.
What I’m going to need more info about that
