Answer:
Explanation:
As we know that two resistors are in parallel
so we have
where we know that
so we have
now to find the rate of change we have
now from above equation we have
The final answer is 51.6 microC which is answer choice b:
Answer: d. I or II
Explanation: A traveling wave has speed that depends on characteristics of a medium. Characteristics like linear density (μ), which is defined as mass per length.
Tension or Force () is also related to the speed of a moving wave.
The relationship between tension and linear density and speed is ginve by the formula:
So, for the traveling waves generated on a string fixed at both ends described above, ways to increase wave speed would be:
1) Increase Tension and maintaining mass and length constant;
2) Longer string will decrease linear density, which will increase wave speed, due to their inversely proportional relationship;
Then, ways to increase the wave speed is
I. Using the same string but increasing tension
II. Using a longer string with the same μ and T.
B. a prism.
This is because the term "angle of deviation" is used to describe the angle at which the light bends compared to the normal of the ray of light
Electric current or electricity
