The chemical change occurred. Electrolysis is used by scientists to make chemical reactions that wouldnt normaly spontaniously ocur. In this case we are getting new gases from water molecul which is change in structure of elements ( we are getting new moleculs)
The relationship between wavelength
, frequency f and speed of light c for an electromagnetic wave is
Using the data of the problem, we find
Wavelength and frequency have a reciprocal relationship. If one doubles, the other halves.
Answer:
The time constant is
Explanation:
From the question we are told that
the time take to charge is
The mathematically representation for voltage potential of a capacitor at different time is
Where is the time constant
is the potential of the capacitor when it is full
So the capacitor potential will be 100% when it is full thus 100% = 1
and from the question we are told that the at the given time the potential of the capacitor is 85% = 0.85 of its final potential so
V = 0.85
Hence
