Answer:
Work done, W = 0 J
Explanation:
It is given that,
Weight of the bucket, W = F = 35 N
It is lifted vertically 3 m and then returned to its original position. We need to find the work gravity do on the bucket during this process.
Work done when the bucket is lifted vertically, W₁ = -mgh
Work done when the bucket returned to its original position, W₂ = +mgh
Net work done, W = W₁ + W₂
W = 0 J
So, the work done on the bucket is zero. Hence, this is the required solution.
The terminology is somewhat arbitrary, however, In this case, you intentionally alter the angle, which then determines the resulting distance. The presumption of the experiment is that distance is DEPENDENT on the angle. The dependent variable will be the how far the rock went. The dependent variable is the variable that you are testing. The first sentence of description indicates that the experiment is to determine launch Θ vs range.The largest range value is to be determined, so the range is plotted on the Y-axis. Angle Θ is plotted on the X-axis. The distance depends on the launch of the angle so the answer will be (D) how far the rock went. It is the dependent variable.
Here is the first question
Answer:
The correct option is that both the ends will remain neutral.
Explanation:
As the rod is grounded all of the prolonged charge will be converted to ground so the overall charge on the rod in absence of the charged ball will be equal to zero.Such that the both ends will not bear any charge.
It is determined by the nature of the green light. Because lasers create light at almost a single frequency, green laser light would appear as a thin line of pure green. Other sources of "green" light emit light at a variety of frequencies, including yellow and blue, resulting in a strong green band in the center that fades into blue-green and yellow-green at the borders.
For example, here’s a graph of the spectrum of a green LED, showing the color range: Attachment #1
and here’s a graph of the transmission spectra of several standard photographic filters, including green: Attachment #2
