PART A)
Equivalent resistance in parallel is given as
now we have
PART B)
since potential difference across all resistance will remain same as all are in parallel
so here we can use ohm's law
As we know i = 7 A current flows through 15 ohm resistance
PART C)
Similarly ohm's law for 20 ohm resistance we can say
Answer:
The law of conservation of matter says that in chemical reactions, the total mass of the products must equal the total mass of the reactants.
Answer:
When you use your control remote, you can see that there is not a "material" thing that comes out of the control remote and goes to the TV, but there is actually energy that comes from the control remote (and this is why your control remote needs battery)
This energy is called an "electromagnetic wave" usually in the infrared range, this means that the energy that comes from the control remote has less energy than the visible red light (and this is why we can not see the light that comes out of the control remote), and this "signal" is read by the TV, in order to change of channel or change the volume.
You even can see that there is a sort of light (electromagnetic wave) coming out from it if you point with a camera to the small bulb that is in the front of the control remote.
Answer is Cation
whilst an anion is the one that is negatively charged after gaining electrons
