Ans is Camels can walk easily in the desert because of their wide feet. Their wide feet allow the weight of their body to act on a larger surface of land reducing the pressure exerted on the land by the camel. As we know, pressure exerted and area are inversely proportional.

[@aryamankaushik6864]

in the first question: It is more difficult for the horse to walk in the sand because its feet are not broad as that of a camel. Which means less surface area, and pressure exerted on the sand is more hence the feet of the horse going inside the sand. Q-2) B 12.5:1 Hint to those who are solving: An elephant has 4 feet not 1.

THANKYOU SIR FOR BRINGING THIS SESSION FOR US!.. THIS CHAPTER IS COMING IN MY ANNUAL EXAMINATION ALSO!.... 😊😊

​@@amarnathtiwari2538 xxx what is this

[@Artsmosphere]

hi byjus, please bring sst for class 8 also like this

[@Priya_sharma49]

Hello sir thank you for this chapter and homework answer is :- 1. camels have broad feet than horse though which they can run easily while horses have solid feet so they sink easily in desert. 2. The ratio is 12.5 : 1 If there is any mistake please tell me sir 😅

[@KAVITAKUMARI-vy6wr]

yes ans of second question is 6.25 : 1

[@YashikaSolanki-nm5cc]

VERY NICE SESSION I LIKE THESE TYPE OF SESSIONS MY EXAMS R FROM 28 FEB TO 11 MAR I ALSO WANT EXEMPLER QUESTION SIR THANK U SOOOO MUCH.....!

[@YashikaSolanki-nm5cc]

IT IS EASIER FOR A CAMEL TO MOVE ON SAND THAN HORSE BECAUSE CAMEL HAS BROAD FEET HENCE LARGE AREA SO PRESSURE EXERTED WILL BE LESS

[@RouhanKhan-rf7cp]

Q1( b) 12.5 : 1 , Q2/ Ans The horse is unable to walk on the desert because it's feets have small area that exerts more pressure,but a camel walks easily on desert because it's feets are broad that increases area because of this pressure is low that is why camel walks easily in desert and not gets inside the sand .

[@mahrosh81]

Why

[@KunalSharma-hc2px]

What you're solving for The ratio of pressure exerted by the girl to that by the elephant. What's given in the problem The girl weighs 50 N The girl wears pencil heels sandals each of area 1cm square The elephant weighs 2000N The elephant stands on foot each of area 250cm square How to solve Calculate the pressure exerted by the girl and the elephant, then divide the pressure exerted by the girl by the pressure exerted by the elephant. Step 1 Calculate the pressure exerted by the girl. Pressure =force upon area Pressure = 50 N upon 1cm square Pressure = 50N/cm square Step 2 Calculate the pressure exerted by the elephant. Pressure = Force upon Area Pressure = 2000N upon 250cm square Pressure = 8N/cm square Step 3 Divide the pressure exerted by the girl by the pressure exerted by the elephant. 50N/cm square upon 8N/cm square = 6.25 Solution The ratio of pressure exerted by the girl to that by the elephant is 6.25.

[@fardheennissar3654]

this is completely wrong. Read the question properly. The girl is wearing pencil heel sandals EACH of 1cm^2 area. So the total area will be 2cm^2. Hence pressure exerted by the girl will be 25 N/cm^2. The elephant stands on feet EACH of 250 cm^2. So the total area will be 1000cm^2 (because the elephant has 4 feet). Hence pressure exerted by the elephant will be 2 N/cm^2. ratio will be 25:2, or 12.5:1

[@user-ku4dv2nj4b]

Bro both are wrong firstly we have to convert cm² into m²

[@fardheennissar3654]

@@user-ku4dv2nj4b that’s not needed.

11:24 Answer: the camels 🐫has large foot then horse 🐎 so they can walk on sand because the ptessure will be distributed on the sand but in the case of horse they have shor foot so they can stuck in the sand

[@sonujaiman9166]

28 March se kis kis ke tension start ho Rahi h RBSC Wale best of luck

[@allinon618]

My tension❤❤❤

[@shashikantsingh5315]

ans sir the camelhas large hooves which reduce the pressure but horse has small hooves which increse the pressure acted upon and the horse will sink down because the are is inversely propotional

[@sanskritigupta1197]

It is difficult for a horse to walk in the desert than a camel because the area of the camal's feet is bigger than horse so pressure will be less in camals feet than horse and his feet will not sink in the sand and camal can walk comfortably on sand

[@ahmedpasha9037]

Hi 2nd comment Byjus you are just wonderful you help a lot of young learners on this platform 🤠 hats of to you ❤🔥🔥

[@rahulmoredrawings5565]

Horse faces problem in walking on sand because it's hooves are not wide . In case of camel it vice versa.

[@naziyabegam5689]

Because horse legs are so short but camel legs are so much longer than horse and in deserts attract the people in the soil

[@KunalSharma-hc2px]

In the topic of muscular force on 4:26 sir showing his body💪🏻 😂😂

Hii princess

[@Ultimate_Gamer_011]

Thank you sir 😊

[@monamannat5007]

Thankyou sir for today's session

[@kavyaonish5519]

Camel is walk on the sand easily because the first reason I can say that they were say that there were camel those have habits to walk on the sand and the horse have habit on the land and the second and important reason that the camel have wide legs compare to the horse. 😊

[@goodstudy]

Sosc form fill Kiya tha kya

[@SB_BKUP]

sir i canbot find the notes through the link

[@adwaithmadhav3762]

weight(force) of the girl =50 N area = 1cm^2 = 0.0001m^2 pressure = 50/0.0001 = 500000 pascals weight(force) of the elephant = 2000 N area = 250cm^2 = 0.025m^2 pressure = 2000/0.025 = 80000 pascals Ans = 500000:80000 = 6.25:1

[@user-ku4dv2nj4b]

Bcz the camels have large and flat feet so the area is larger and force is smaller so it does not sink in the sand

[@aayushtyagi3587]

Sir you should speak hindi for more good explanation for some student❤

[@vishhalmodak163]

Sir can you please make video for class 9th 🙏

[@user-wp6bc8wn1u]

The feet of the horse are small which causes more pressure while the horse is loaded whereas the camel leg has more surface are causes less pressure.

Please sir class -8 complete science syllabus revision

[@nirmalarathi2525]

because camel foot area is more so pressure will be less whereas horse foot area is short thus pressure will be more and ques 2 answer will be b 12.5:1
