A crane lifts a 3.3 kg crate from the ground to a height of 1.6 metersIts held steady in that spot for 30 seconds, then lowered back to the groundI need to find how much work is done in each of the three stages1-raising it2-holding it3-lowering itI'm not sure what formula(s?) for work would work with all three.
You can'tYour desktop computer has no capability of sending signals through the airA wireless router can do it, but your desktop computer can'tYou can do the other way around (wireless through a cord) but not the other way around.
If your computer has both an Ethernet adapter and a wireless adapter, you can use Internet Connection Sharing - hit F1 on a blank spot on the desktop and look for ICS - it'll give you directions(It's the WORST way to do it - it's much better to use a wireless router.)
Remember, that Work Force displacement cos angle theta In this case, theta 0, so the work is simply force times displacementThe work to lift an object up is it's weight, so we have 3.3(9.8) as the forceOur work is then (3.3)(9.8)(1.6) While holding it, we are not moving it, hence the work is 0Lowering it, we are moving it -1.6 m, so the work is negative! THe end result is W-3.3(9.8)(1.6) The interesting this is you actually have not done any total work during the process! As your displacement is 0, your work done total is actually 0! But since you're only looking at each individual stage, it's not soyou'd end up with the same result if you simply added everything together.
