At least $25 \mu \mathrm{g}$ of tetrahydrocannabinol $(\mathrm{THC}),$ the active ingredient in marijuana, is required to produce intoxication. The molecular formula of $\mathrm{THC}$ is $\mathrm{C}_{21} \mathrm{H}_{30} \mathrm{O}_{2}$. How many moles of THC does this 25 \mug represent? How many molecules? (b) Caffeine, a stimulant found in coffee, contains $49.5 \% \mathrm{C}$, $5.15 \% \mathrm{H}, 28.9 \% \mathrm{~N},$ and $16.5 \% \mathrm{O}$ by mass and has a molar mass of $195 \mathrm{~g} / \mathrm{mol}$. (c) Monosodium glutamate (MSG), a flavor enhancer in certain foods, contains $35.51 \% \mathrm{C}, 4.77 \% \mathrm{H}, 37.85 \% \mathrm{O},$ $8.29 \% \mathrm{~N},$ and $13.60 \% \mathrm{Na},$ and has a molar mass of $169 \mathrm{~g} / \mathrm{mol}$

The question in this there is a car which is traveling with certain speed, overtaking another car with certain exploration which was initially a twist. Okay, so we have to assume the length of each card with five m. So we need to find the total distance used to. I use an overtaking. Okay, if this is carvin okay, this is carbon, let us say uh which was initially at rest. Okay, initially at rest and then I started moving with execution of to meet a person in a square and this is the second car which was moving which was moving with speed of 20 m plus again with constant exploration of course 20 m purse again. And let us say after time T they're overtaking complete 20 m purse again. So this car or thinking complete. So it will be like this. Let's see if this car is A. Does it be A and B. Yeah. Okay. Mhm. No, we'll be assuming that at Equal to zero overtaking starts and at equal to t overtaking ends which means a distance covered distance covered by both the cars in time. T should be equal, which means distance traveled by. This car will be 20 and two T. Because of its constant speed and distance covered by this car will be using as equal to U. T. Place half a. T squared. So in this case distance covered will be you were zero. So half 80 square. So too the square. So simply obviously this is a T. Square. So both both distances should be the same in this case and should be the same. But We have to add these five m and five m All we can say five m for this car and five metaphor this car. And then you're making the distances to be equal. So we should be writing Squire place 10 equal to 20 T, which means do you square minus 20? T Plus 10 should be equal to zero. So he will be according to the quality formula minus b 20 plus minus B squared. So 400 -40 divided by to a 20 plus minus 360. 60. And the route divide by two. Well, this would be 20 plus -18 points 97 divided by two. There would be two times Which would be after taking a negative sign. It will be 20-. They didn't find 97 x two Which is 0.51 in two seconds. And if it is a positive sign could be 20 place it in point 97 x two, ridiculous, 18.97, Divide by two. I was 18.975 which is 19 point for it. Fire statement. Okay, so now These are two values of two values of T 1st value That is 0.5 and three seconds will be event the overtaking has been completed And T to 19.4 8/7 corresponds to the same situation. Action. Okay, sure. The distance would be Okay. Total distance covered would be 22. Okay. Okay, so and the total distance covered would pay 2018 to 19.485 seconds, 17- 19.45 seconds. The candidate nine point seven yeah. Okay. Meters And plus the length of the car with a five minutes 394.7 meters. So they should be the answer. Thank you. An option # eight. Thanks.

Hello and welcome to this video solution of numerous. This question is based on circular motion. So we are given that a car is traveling on a straight road at sudden velocity and it moved over a hump in the road. Okay, let us tablet the given parameters which is first velocity of the car, which is given us nine m/s. Now it is also said that the hump may be considered as the arc of a circle of radius 11 m. So let's say the radius of the hump is given us 11 m. Okay, so now we are asked to find out what is the apparent weight of a woman whose weight was 600 Newton will be once he writes over this hump. So the weight of the Metformin is given us it's 100 Newton. Now let us draw this scenario. So you have got a road and there is a hump like that. So now when you move, when the car moves over it, the thing that will happen is let's say you've got a deal that is moving over now due to the circular movement of this, of the trajectory of this car. It will be living in a circular manner over the summer. So of course the net force that will act yes towards this center of the whole. Huh? So this is equal to the centripetal force. And we have got to other forces. One is the weight of the woman which is also acting town works. And the normal reaction in due to this home. So let me denote the normal reaction has them. Also we have to we have to know that the normal reaction is actually the apparent weight of the woman. The senate. To remember now we have to now to get the value of the brand with uh which is actually asked in the question uh this weekend calculated by using the net force which is given us the net force. The net force is equal to wait minus the normal reaction. And this net force is nothing but the centripetal force great minus the normal reaction. Now to calculate centripetal force, we need to apply the mass of the woman V. Squared by our and here we have The weight w. is already given up 600 minus the normal reaction on that point. So here we need to find out the mass which is nothing but the weight of the woman by the explosion nuclear peace. So I'm just terribly writing it has 600 By 9.8 rate. So this gives us a mass of the woman woman Times the velocity is given as nine m For a second. So nine squared by the radius. The radius is 11. Now this is equal to 600 minus and from here we get an equal to let us calculate It's 1 49. Yeah, it does. Yeah. Thus we see that the original weight of the woman was 600 million. And while moving along along this hump, It has reduced to 1 14 8. So the apparent weight is 1:49 Newtons. So this answer, good option questioning. Right now let's move on to the second part B where it is asked that what must be the speed of the card or what is hub so that she experiences witnesses for weightlessness. You have to remember that the normal reaction must be equal to zero. Now we play the same equation here. Yeah, if you see Fc equal to F. C. Equal to w minus. Embry. No. Here we have an equal to zero. So F. C. We know that M. V. Squared by our I don't know, is equal to wait. Let me write us MG. Because the path will get can tell consent on both sides. Now. We have got to be equal to go to work here. This gives us equal to 9.8 times our insulation rate. Yes, that gives us 10.4 meters. Perfect. So when the car was moving at 10.4 m/s, then the woman has felt a weightlessness. So this is the answer to part B. I hope this is clear to you and have a very good rest.

Should we have to get you into balletic Wythe in the dark? Forces have proposed 20 piece choir. So had indeed this one. So force. No, Billy, Do you want tea into one? Soon square you and darker.

In this problem, we're even the most acquire is equal to 1500 kg on the spit off. The car is equal toe, 5.0 m first scanned and the coefficient of friction is equal. Toe their 0.6 on the consumption of energy Doing while driving on ST is equal toe 15 miles Bergen and and we know that energy off on Galen is equal to 1.4 multiplied. I think about a job. This is the energy content We cannot continue. One goodness in the first book is experience constraints. So exploration with with zero So you consider it for vertical direction, cortical direction, political action, some all forces in my direction. We go toe and minus empty. Where is normal? Force is 20 or we can say that and is a good energy. Penny's got em is 1500 AM is equal to between 100 Casey on Jeez, Gatto 9.8. Which a person can spare. So when you Paris you get I won't force the car too. 14,700 Newton? No, for his introduction for his intel direction. So all forces the next passion is good too. F a minus freshman force. They go to zero where F a is equal to Proposition Force, which can written is cough inter fiction very normal force and cautioned of regions with ponzu six. Multiple have unknown force 14,000 certainly gluten. When we saw this, we get a pension force is equal to Well, you're proposing force F A is equal to it. Includes 80 punitive, which is the answer. The first part of this question while in the second part. But because you know that always got toe force with speed, which is called 882. You didn't like 5.0 m per second. When you place, we get powers for the foot 1004 110. What is virgins? Goto F D. Where if he's eating and drinking on distances 15 months and the one mile contains 1609 m formal. So why don't we? We go to 21 for three major. No, we confined efficiency very in formula work, then directed by New Jersey, which is good to 1.4 and have a think about it so and working is $21.3 million and one before but I think the edge of the making is 140 individual. When you saw this, you get to 25 percentage efficiency is equal to 15% which is the answer of the second part of this question.
