I think it’s b because gravity pulls down or tword and that says moving away I could be wrong but I think it’s b
Please don't use a car's ignition coil as an example. Let's just say it's an ordinary transformer. If you connect 1800 volts AC to one side of the transformer and you get 12 volts out of the other side, then the turns of wire are in the same ratio as the voltages ... 1800/12 = 150.
A car coil doesn't work like an ordinary transformer. In a car, you put 12-volt pulses into one side, and you get voltage out of the other side that's high enough to fire spark plugs and ignite gasoline.
So you've actually got the primary and secondary windings labeled in reverse in the question, and you're actually using it as a step-DOWN transformer.
Answer:
cm
Explanation:
= height of the object = 2 cm
= height of the image
= distance of the object from the mirror = 30 cm
= focal length of the mirror = 25 cm
= image distance
using the mirror equation


cm
using the equation


cm
Answer:
Try and depend more on renewable energy sources. Use products that are more energy efficient. Make use of lighting control measures. Maintain climate change
First, we need to find the number of protons, which is the total mass divided by the mass of one proton:

protons
Then, the total charge is the number of protons times the charge of a single proton:
