A pump is required to lift a mass of 850 of water per minute from a well of depth 15.0 and eject it with a speed of 18.6 .
How much work is done per minute in lifting the water?
Take the free fall acceleration to be = 9.80 .
1.25×105 J
Correct



Part B
How much in giving the water the kinetic energy it has when ejected?
1.47×105 J
Correct



Part C
What must be the power output of the pump?
Take the free fall acceleration to be = 9.80 .

earth is it self a bigger magnet, which protects us from out side radiations. it means it is very strong reaching out to hundred miles in space. we need changing flux to generate a current , which is continously changing in case of earth. so we have all the tools for electricity production. we just need a coil. but this does not work as lot of coils are there but there is no electricity flowing from them. why??

im doing a Force and acceleration lab. I need to collect data for force friction. If I already have mass, distance, time, final velocity, acceleration, force(f=ma), (Fg=mg).

How do I solve for Force friction? What do i need in that list.

Question 2 (if possible)
How do you get Force myu (u) if I have mass, Fg, Ff(kinetic), and F.

How do you get Force myu in this case?
Thanks for your help

One website said that the advantage of a series circuit is that you can add more power devices, such as more batteries, and increase the force of the output. What does that actually mean?

Now, I've been thinking (I sometimes do that ya' know!): I mean, gee whiz, when those ballerinas pull their arms in, they really spin like crazy! So if we'd just sit our fat rear ends down (and stop hangin' out at the door waiting for quitting time), wouldn't time fly by so we could go home sooner? (Ouch, I just bit my tongue and cheek!)

And answer how you interpret the mechanism of the Mathematical Dance of the Origin and Evolution of the Species beyond man (one of Tarcísio Brito’s nine theses). Just get a piece of paper, a pen or a pencil. Draw a circle on the paper and draw a horizontal line dividing the circle into two halves. Draw a short curve line ended in an arrow to the right. Write on top: Our History. Do the same on the left, at the bottom part and write it down: Pre-History. Now get the pen or the pencil and go through the indication of the arrows. You have gone throw the Dance of the Cycle of Our History, alternated with the Cycle of Pre History. This dance reveals the infinite past alternated with the infinite future. (Where we came from and where we are going to).

I'm trying to do a microwave guide (10.5 GHz, wavelength: 2.85cm ) ..I've been searching and I still don't know if I should do a rectangular or a circular one , please help me to know wich one it's better ( there are also eliptical ones but I don't like those..it may be better but I'm too lazy to look at the theory behind :/, unless you are patient enough to explain it to me ..but it's faster to give me your reasons to choose among a circular and a rectangular one.
thanks!
