Answer:
Total Energy Input = Total Energy Output / Efficiency
Explanation:
The expression written above is not true about the energy conversion devices.The energy conversion devices convert energy from one form to another for of energy for example :- take a light bulb it converts electric energy to heat and light.There is no efficiency involved in the energy conversion devices.
Answer:
Option A i.e.,Disable the superfetch to improve performance is the correct option.
Explanation:
The following option is correct because when the user is trying to maintain the performance of their system then, he observe that the following tool that is Task Manager display that the superfetch using the CPU time in high rate then, he decided to disable the Window service tool that is superfetch to increase the responding time of the system for improving the performance.
Answer:
1) Choose Slide
2) Transition Tab
3) Transition To This Slide
4) Select New Transition
Explanation:
There are 4 main steps that Evie needs to take in order to accomplish this. First, she needs to choose the slide that she wants to apply the transition to. Secondly, she needs to click on the Transitions Tab at the top of the application. Thirdly, she needs to go to the "Transition to this Slide" section of the tab.

Answer:
19.71 ms
Explanation:
The disk rotates at 3600 rpm, hence the time for one revolution = 60 / 3600 rpm = 16.67 ms.
Hence time to read or write on a sector = time for one revolution / number of sectors per track = 16.67 ms / 32 sectors = 0.52 ms
Head movement time from track 8 to track 9 = seek time = 2 ms
rotation time to head up sector 1 on track 8 to sector 1 on track 9 = 16.67 * 31/32 = 16.15 ms
The total time = sector read time +head movement time + rotational delay + sector write time = 0.52 ms + 2 ms + 16.15 ms + 0.52 ms = 19.19 ms
