Star A - (color) red-orange (type) main sequence
Star B - (color) yellow (type) supergiant
Star C - (color) blue-white (type) white dwarf
Star D - (color) yellow (type) main sequence
*im pretty sure these are correct if I remember clearly*
Answer:
a) phere A has 8 negative charges and sphere B has 2 positive charges
b) each one has then 3 negative charges
Explanation:
In this case, it is asked to determine the charge of the spheres in two conditions
a) Before connecting the cable, sphere A has 8 negative charges and sphere B has 2 positive charges
b) After connecting the cable, as the spheres are metallic, the load is distributed, we have
q = 8 -2 = 6 negative charges
these charges are distributed between the two spheres, each one has then 3 negative charges
Answer:
W=1.5×10⁸J
Explanation:
first change the km to m then you get 10000m
- W=Fd
- W=15000*10000
- W=1.5×10⁸J
Power in most circuits could be analysed and broken down into two categories
-Power dissipated by resistive components
-Power delivered by the electrical sources.
If you are working with Alternate current (AC) sources, the analysis of the power consumed in the circuit will deal with complex numbers and the introduction of new terms such as active, reactive and apparent power.
All this depending on the frequency and the components used in the circuit.
the answer is a
Explanation:
it's a because 5n time 4 will give u 20n
