Answer:
We conclude that star moving toward observer.
Explanation:
According to the theory of doppler effect of light.
There are two kind of shift 1 ) Blue shift 2 ) Red shift, in which
1 ) if source of light moving toward observer so the apparent frequency of light increase( wavelength decrease ). This is which we call blue shift
2 ) if the distance between source and observer is increase, so the apparent frequency of light decrease ( wavelength increase ). This is which we call red shift.
Here, in our case wavelength of H-star is decrease so we can say that star moving toward observer ( Blue shift ).
Answer:
Negative
Explanation:
Liquid electrolyte inside battery has work to transfer the charge from one terminal to other terminal..
So here this is carried out by the charge which has more mobility and it must be more in numbers.
So here for more mobility we have to take the negative charge or free electrons present in the electrolyte which carry electricity from one terminal to other terminal with least resistance
so here correct answer would be
b.) Negative
An example helps clarify the difference between an analysis, a deter- mination and ... departments analyze samples of water to determine the concentration of ... moles of Cu2+, and cylinder 2 contains 20 mL, or 2.0 × 10.
I can't find the attached circuit.
Maximum power transfer occurs when the load impedance
is equal to the internal impedance of the power source.
