Pulleys Work Questions:

Question #1:

HELP! CALCULUS RATES PROBLEM?

Q. A dish is pulled into a dock by means of a rope bespoken to a pulley on the dock. The fastening is attached to the bow of the boat at a saucer 10 ft. below the pulley. If the fastening is pulled through the machine at a rate of 20 ft./min, at what evaluate will the boat be approaching the dock when 125 ft. of rope is out?
NOTE: I WILL REWARD BEST ANSWER WILL 10 POINTS INSTANTLY TO WHOEVER ANSWERS CORRECTLY AND SOONEST! THANK YOU ALL, AND PLEASE SHOW WORK!

Question #2:

The rate at which work is done is called energy ?

True or simulated physics questions.
When the respond is false , gratify state why:

15. The rate at which work is finished is called energy

16. When we carry an object across a shack without lifting it or sitting it down we do no physical impact on it.

17. In physics, the amount of work done on an object is the creation of the force exerted on the goal times the instance the object moves.

18. The energy an goal has by morality of its motion is titled its kinetic energy.

19. The energy an goal has by virtue of its location is called its possibleness energy.

20. Energy transforms from digit form to added with no net expiration or gain.

21. The machine is a device for multiplying force or dynamical the content of force.

Question #3:

true or false physics questions. very simple, please help!?

When the respond is simulated , gratify land why:

15. The evaluate at which impact is done is titled forcefulness

16. When we carry an object crossways a shack without lifting it or sitting it down we do no fleshly impact on it.

17. In physics, the amount of impact finished on an object is the creation of the obligate exerted on the object times the instance the object moves.

18. The forcefulness an goal has by morality of its change is titled its kinetic energy.

19. The forcefulness an object has by virtue of its location is titled its possibleness energy.

20. Energy transforms from one modify to another with no net expiration or gain.

21. The pulley is a device for multiplying obligate or changing the direction of force.

Question #4:

Mechanical Advantage?

Using a force of 300N for 4 meters, and having a machinelike advantage with pulleys 6. How heavy is the car? What is the work of the pulleys?

Question #5:

If bolt in tensioner pulley is too loose or too tight, how long does it take to snap?

We took our 99 ford taurus into the shop for an oil pan gasket. Quoted 250. Paid 564. I asked them to to just countenance at a couple of other things, "they misunderstood" and intellection I desired the work to be done. FINE. They said there was lubricator all over the belt, so they clean it off. Brought it home weekday evening and didn't intend it again until Monday. Started it up and "service engine soon" light came on, called and they said to bring it in on Saturday. Tuesday... the decamp in the tensioner machine completely snapped off, feat it to revealing fluid everywhere. When I called the garage they said they never touched the track and then said they never took it out to clean but did wipe it down. So apparently it was touched in whatever artefact or another, my question is, if they tightened it likewise much or untangled it likewise much, how long-ish would it hit taken for the bolt to snap? And does this particular difficulty hap alot with cars??
the changeful unseaworthy is from the belt coming off and i believe it is from the radiator, and yes i get that they crapper decent it without attractive it off
this is the work they did: oil pan gasket, sway bar link, gas sensor,oil change, EPA,exhaust gasket, and an inspection.

Question #6:

Should I pay for a repair that wasn't fixed right the first time?

I went to a topical garage to hit a serpentine belt replaced. Drove my car home most 5km car worked fine. Around an hour after went to go somewhere, started my automobile and what a loud admit with a lateral of smoke, so I invoke of the car. After calling the garage to tell the repairman, he said he'd become discover and take a look. This went on for two weeks then eventually he showed up. 'Well I'll verify it to my shop and see what's wrong" he said. An distance or so after they convey with my car. 'Belt wasn't on properly" he said. 'Had to add your machine to make it fit" he said. "called the moneyman and they said it was the correct digit for your car" he said. Wanted paid again!! Now my car won't go more than a km then it jerks and stalls, never did that before. Takes me a while to get it feat again, so I have been mitt without transportation. Single employed low income mom here, cannot give to verify it elsewhere correct now. Any advice? What do you conceive most stipendiary twice for something they should have fixed correct when I paid them to in the first place?

Question #7:

conservation of mechanical energy problem?

this discourse seems ultimate enough, but i've been opened at it for the entire period and i couldn't attain any FCKIN sense discover of it.

a country of accumulation "M" is pulled up a smooth shape by added block "m." the pulley is ideal. the ramp is frictionless. rattling basic. the setup is something same the pic shown here:


however, the "drop height" for the hanging mass extends far beneath the height of the shape itself. so i surmisal it's same an shape set up over the bounds of a table or w/e.

now i need to prove finished work-energy theorems that rate = sqrt 2gh m-Msinφ / M m . i've derivative the formula for rate on a insipid incline, but i'm wondering if i did it wrong or something, because the formula i'm questionable to prove here is supposed to reduce to the aforementioned thing. it's driving me crazy. anyone get this?

Question #8:

Do feminists dispute that men are physically stronger, or that modern technology didn't always exist?

Because in my experience, modify most feminists pass that men are physically stronger, and indeed, this has been utilised to justify a aggregation of their double standards, much as "It's worse for a Negro to impact a woman because he's stronger," and so on.

But the way they go on about how there's no think ground men and women can't do the same jobs, I have to wonder if they're aware that throughout most of history, "work" meant a super amount of fleshly labor. It wasn't movement in an air-conditioned office, filing paperwork same it is today. Given this, and also given the demand of reliable relationship control, it seems exclusive natural that society would evolve to hit men employed and women in the home - and perhaps also to analyse men as slightly more important than women, as we were more essential to society in this regard.

Yet, rather than accept this basic, ordinary significance explanation for why gild evolved the way it did, feminists seem determined to insist that this has, in reality, been a large conspiracy of men wanting to bedevil women throughout the ages. Apparently, backwards when "work" meant hauling onerous shovels of combust every day, or hunting for ferocious animals with nothing but our fists and man-made spears, or selection downbound super trees, shipping them for individual miles, cutting them up, and assembling a house with them using nothing but our bleak hands and maybe a pulley, women were constantly begging for the chance to injure themselves this way too, but us evil, vile men insisted on oppressing them by demanding that exclusive we got to be tortured this way. I guess maybe we figured women were hogging all the injure with the pains of childbirth, and there wouldn't be any mitt over for ourselves unless we kept all the back-breaking work for us.
I conceive it's queer that you're locution I'm the digit who hasn't intellection that through, Cirbryn.
Kat: I concord that women's natural roles should be reputable more, and they were play in most the nonmodern ages, and reaching their peak in age times, but still continuing to the '50s. It wasn't men at least, not on a grandiose bit having a lack of respect for women's natural roles that led them to enter the workforce, it was feminists promoting that view, that those roles were somehow inferior to men's. I will acknowledge that maybe men should hit taken meliorate care to remember and appreciate those primary roles that they filled, or crusade might never have succeeded.

As for women wanting to start the men to establish they were confident of more, I would have to say they've failed miserably at that, presented how men still outperform them, and how the only reason they've been healthy to contend at all is because they've had to inconvenience us with things like assentient action and women-only scholarships or pressuring colleges to verify in a
certain sort of girls. At this point, I conceive it's instance for women to go backwards and feature "Okay we proven and failed, it's time to go backwards to our uncolored roles now."
But men don't difficulty each another for an "equal" shot at things. Men endeavor by the rules and acknowledge cause and effect. You talked most transfer others down, and it's women who are transfer more privileged men downbound in order for this "My fair share" deal.

Either way, I conceive it's essentially stupid to break up the family unit over some petty "I poverty to be equal," crap. But we're going off topic now, so you can e-mail me most this if you poverty to continue.
CIrbryn: No, actually, my question was very clearly about the pretence of feminists who claim women were oppressed, and not most whether women should work today, and everyone who feature this and didn't already have a chip on their margin apprehended that point. This is exactly why I said it's funny that you think I haven't thought this through. I'm not going to pay paragraphs feat back and forward with you patch you essay to dissect what I wrote and essay to argue that it meant something other than what everyone else understood it to mean. Everything I wrote was very clear.

Question #9:

Physics forces and work?

A ultimate machine: two pulleys unreal to support displace a heavy load. A fastening runs around digit massless, frictionless pulleys and the object hangs from digit pulley. You hold a obligate of ratio F on the liberated modify of the cloth and the object rises at a unceasing speed. Be sure to draw a rank free-body if it is needed to respond any part of this problem.

a If the pulley/object grouping is to move up a indifference h, through what distance must the applied obligate move? Express your answer in cost of h.
b How much impact is finished by the rope on the pulley/object system? Express your answer in cost of m and h.
c How much work do you do? Express your answer in cost of m and h.

Question #10:

I feel defeated. Impossible car problem. No one knows the answer. HELP!?

2002 author Mustang, V6, Base, 3.8L, 150,000miles

Everything I try on this car doesn't work. I've clean MAF, enrich body, IAC, EGR, replaced hoses, checked for leaks, replaced alternator, no analyse engine light, took to an exhaust place said cats were fine, kindling wind readings fine, render gauge employed fine, NO CHECK ENGINE LIGHT, meet done so such to this car. Yes the analyse engine light works, was on cod to a bad EGR pipe and absent PDFE sensor. I immobile that, light gone. I hit changed spark plugs, wires, and done lawful maintenance on it oil, FUEL FILTER, air filter, etc. .

It jerks and hesitates, stumbles and loses rpm when it's movement idle in my yard, stopped at a flushed light, and occasionally when I'm driving it. I had a feeling it was my alternator, so I disconnected the power cloth to it. It worked perfectly. I sequential a new one, put it on there, and it's ease doing the same thing. Pulley system and curved belt hit been denaturized idler pulley, machine tensioner .

NO ONE CAN FIGURE THIS OUT! It still jerks, idle changes in sound as it stumbles. Guys at Advanced Auto Parts said the alternator was making a loud whining noise, but it's sort new. It proven fine.

Why is it ease jerking/hesitating? RPM dip down, raise correct backwards up. Engine is very strong. Ran seafoam through it, good fuel, fuel injector cleaners... I don't see anything wrong with the electrical wiring coming from the alternator.

Please, just support me. I don't know what added to do. I feel defeated. Heck, I'll modify PayPal someone some change if they encounter discover what the difficulty is for me. I meet can't figure it out!!
