A mountain climber, starting from rest, does work in climbing upward. At the if top, she is again at rest. In the process, her body generates $4.1 \times 10^{6} \mathrm{~J}$ of energy via metabolic processes. In fact, her body acts like a heat engine, the efficiency of which is given by Equation 15.11 as $e=|W| /\left|Q_{\mathrm{H}}\right|,$ where $|W|$ is the magnitude of the work and $\left|Q_{\mathrm{H}}\right|$ is the magnitude the input heat. (a) Is the $4.1 \times 10^{6} \mathrm{~J}$ of energy equal to $|W|$ or to $\left|Q_{\mathrm{H}}\right| ?$ (b) How is the work done in climbing upward related to the vertical height of the climb? Explain.
Problem The vertical height of the climb is $730 \mathrm{~m}$. The climber has a mass of $52 \mathrm{~kg}$. Find her efficiency as a heat engine.

Question. What idea? By burning off. How's Engram off that? How's end gums? All that each gram concludes. Student nine pillow galleries so 1000 ground will compute. How's end into nine in the for one, it's six jewels because one kilocalories goto for wondered six jewels and only 20% off. This amount of energy is utilized so we can write zero point so in tow this total amount of energy This is that propel utilized energy. Now they should be well to the work done by dies too. Then bourbon by that student is equal to increase in its gravitational potential. Energy in, uh in Chaminda is steps so we can read the mosque. 75 Indo 9.81 Indo that total height he s climb which is it be in 20.15 And if he has climb by nine end times then we can multiply this with and now on solving it we will get en equal. Do It was before wine He had me every good the students gravitational potential energy or the world Denbigh this student in end times Hilda total energy gain from the burning off the 1000 drum off that now that by water is equal to that increasing the potential energy which is 17 5 into 9.8 into a day in 20 point within. This is the total I upon that time begin just 65. So during this we will get up hours 1 36 works and we know that one horsepower is equal to 7 46 4th So this will be able to zero point one a 19 What hearts forward. This situation is not practical. And this way overturning the fat is not a practical way.

Here we have two equal toe and multiply C. I replied The F minus D i n divided by time require This gives the constant power that can give desired heating. Yeah, for the A, we have cure equal tow am and to see into, you know, do you have minus D A n divided by time required you never here because this gives the constant power Mhm. This keeps the constant follow that can give desired hitting. So thus plugging in value does plugging in values we have que quil too. 250 kz multiply for K G divided by K G minus. He multi play 65 c minus 25. See here By simplifying this, we get the value zero point 55 fight six k w just groveled. This is the answer No, For the next we have I am in to see into de capital T by d t and integrated by this we get no purity equal Tow em, See 30 now by solving days or we can write it as oh, look your duty divided by M c. Now integrated integration is done by the Simpson's rule. So we get the integrated value is integrated. Value ease. Integral value is call to 40 Zito, TV seven Okay, G on the integration is done by Simpson's rule. So for the next here, there, Delta T called 400 37 divided by 250 divided by for So this will be equal toe 40 point 037 c. Does the temperature equal to does? Temperature called toe? 25 plus 14 point. Yeah. 037 equal to 65 0.3 70 Patton. Mhm. This is the answer. Self be is the answer Now for the next. Yes. Yeah, home. We have 20 k w. Did you per minute called tau zero point? Yeah. 33 to me kw per second. Now we have de que bye de de equal toe 0.33 three when cute equal toe four right beauty, equal toe for so thus after 10 minute after in a minute, we get trick or do 100 The last 0.33 three d and we have we have delta. The equal toe. No Q d t divided by EMC now for explosion toe occur to equal to 75 c and we are already at Tickle Toe 65.37 c thus Delta equal to nine point 963 Celsius. Also, um, into sequel toe. Also, how do we have be equal to 75 c and already have tea? Equal toe 60 5.0 37 See on does a delta T 30 equal do 9.963? See here also we have I am in tow. See equal toe four into 250 equal toe 1000. Thus we have now log zero to t 100 the last zero 0.33 three d equal toe nine point 963 x That's multi play. Bye. 1000 equal toe 9963 Here now we have then 100 de plus zero point zero Sorry. 0.3 three Pity divided by two Do you square call to 9963 Solving this we get the equal toe 87 point zero to second, which will be equal to 1.45 minute Here this is now. That's after time that that lapsed after 10 minute I mean dead elapse. Thus time a call to 11.4. Five minute. Yeah, I'm sure this is the answer

Marcel Primaries 52 kilogram were taken distance covered by primaries 700 30 meter. So internal energy used to buy a climber doing motion is 491 times tended of our six a jewel So this energy is off then Bye Climb error through metabolic processes the collision for if you can see up primaries if you can see is a photo wrote down upon inputted we tickle toe working upon s climber newsies It's an analogy is input so we can write dildo you in place off inputted here world in by climate ese mg edge Here I am is a mess D's getting written expression This is MD is weird off climber times it use their distance There is a vertical distance The glamour has to do work two moves ahead to hide it A bomb Delta you here m iss 50 do kilogram value off these nine point and meter par sickens appear into what tickle hide covered by glamour is 730 meter a bomb and draining energy used is 491 times 10 to the power six do so This gives us if you can see equal to you Don't want 09 we want to express if you can see in person days For that we have to multiply it by 100 the physical to 0.9 Multiply 100 person dish The physical too nine barsam. So if you can see our feet Injun, there is a body off as you need is approximately 9%. This is efficiency. Have climber not it Lead Sorry for this.

Question number 36 like that's first calculate the energy required to climb it. He stares this energies 30 in so hi 0.1 pipe in the X elation due to gravity 9.8 into the moss off the person of diggity. This is the total gravitational potential energy required to complete one flight up 80 steps. So if and and flights are taking, then this is my big light but and and now this is the total energy that should be fun by £1 off that £1 off back means four by they wind six grams off that So this is multiplied by 1 g of fat gives 9 kg calories so multiplied by nine in Goa board one year six George And this is the total amount of energy liberated from £1 off that so only 20% off. This energy is used up as mechanical energy. So multiplying this by 0.2 This is very quiet expression again Do I sing it? This is the number of steps in a plight. This is the height This is excellent Shin due to gravity And this is the mosque off the person this is the bit off fat burn. It is amount off kilo calories for 186 jewels in one killer calorie and 0.2 times and the deep from practice used up in McGhan salinity. So solving this people get and equally toe while it one foreign three. This is the number off lives which should be taken do burns £1 off body fat This is done support by day and for five b that by what is be equality, total energy spent in one light that it's total energy spent in climbing off light off it be Stubbs. So this energy that be Indo 0.15 in the nine point it in the 50 you are dead by 65. This isn't quite it too 91 but and the writing it by 746 we will get zero point 1 to 2 hard spooling So this is not a practical way to lose the weight
