Answer:
60 J
Explanation:
Given,
Work done to push the box = 100 J
Energy dissipated by friction = 40 J.
According to work energy theorem work done is equal to change in kinetic energy.
Change in Kinetic energy = Work done by student + Work done by friction
Change in Kinetic energy = 100 J - 40 J
Work done by the friction will be negative because it will act in opposite direction of force applied.
Change in Kinetic energy = 60 J
Answer:
I'm confusd waht u m me ljhnab
Explanation:
Answer:
Explanation:
The minimum depth occurs for the path that always takes the smaller portion of the
split, i.e., the nodes that takes α proportion of work from the parent node. The first
node in the path(after the root) gets α proportion of the work(the size of data
processed by this node is αn), the second one get (2)
so on. The recursion bottoms
out when the size of data becomes 1. Assume the recursion ends at level h, we have
(ℎ) = 1
h = log 1/ = lg(1/)/ lg = − lg / lg
Maximum depth m is similar with minimum depth
(1 − )() = 1
m = log1− 1/ = lg(1/)/ lg(1 − ) = − lg / lg(1 − )
Answer:
change your computer date/skip the videos
Explanation:
hi there! i've been using brainly for free for some time and found that there a few ways to bypass some of their free member restrictions.
first off, there's really not an easy way to skip the video, unless you want to get technical. however, i've found that you can drag on the grey video bar on the bottom of the ad to skip to the very end, thus getting you the answer you need very quickly!
also, brainly has a 7 day answer restriction in place, which you can easily bypass by changing the date on your computer! an easy way to do that is to hit the Windows key and type "date", after which a setting will pop up that reads "Date & time settings". click on that or hit enter. then, tick off the slider that says "Set time automatically", and go down to "Set the date and time manually", after which you'll hit "Change" and change the day to a couple days in the future. give it a second, refresh the brainly tab or re-search up your answer, and you should get a lot more daily answers! one thing i must say about this method is that your computer's date will no longer be accurate. to fix this, you'll have to re-tick the slider that reads "Set time automatically", and it should fix your clock.
one more thing is that, instead of sending your parent an email, you can try to send yourself that email! unless it's an advertisement for buying brainly premium, there also should be no reason to even send the email in the first place, so try to bypass that when you can.
i hope this helps you!
