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.
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.
The correct answer of second question is 25 is to 1 because The elephant has four foots each is 250cmsquare for 4 ft it is 1000 CM Show the pressure of elephant is 2000 by 1000 which the pressure is 2. The girls pressure is 50 / 1 which is equals to 50 50 /2 which is equals to 25 is to 1
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 😅
12:39 homework question answer (a) since the formula of pressure is f/a then the pressure exerted by the girl = 50/1 (applied force of 50 and area of 1) which is 50 pascals then pressure exerted by elephant = 2000/250 which is 200/25 which is 8 pascals ratio = 50:8 which can be represented as 50/8 which is 25/4 which can be written as 6.25:1
Bruther.....first of all SI Unit of pressure is Newton/msq and not Newton/cmsq so first you need to convert the cmsq into msq and then divide it by newtons.... second of all...the elephant has 4 legs and not 1 and the girl has 2 legs and not 1 so the answer would be 12.5:1

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
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
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.
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
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 .

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.
Ans is camel is having bigger feet than a horse which means the area of contact is more because the area of contact is more the pressure will be less. Horse's feet are smaller than that of a camel which means that area is less so pressure will be more thus the feet of the horse will go inside the sand
We use camels rather than horses as horse have small feet and exert more Pressure on sand hence they can't be used in deserts as they can't move while horses have padded feet which allow them to exert less pressure on sand
it is because camels have padded and broad feet which decreases the pressure acting upon the surface of the feet of the camel and the sand present in the desert.
It is difficult for a horse to walk in a dessert as compared to camel because foots of camels have big surface area than horse so the pressure of land will be less to it’s foot
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
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. 😊
Camels hooves have more area than the hooves of horses. So the pressure acts on the horse's hooves more than the camel's hooves, resulting in the sinking of the horse, making it difficult to walk

Mujhe bhi
12:39 homework question answer (a) since the formula of pressure is f/a
then the pressure exerted by the girl = 50/1 (applied force of 50 and area of 1) which is 50 pascals
then pressure exerted by elephant = 2000/250 which is 200/25 which is 8 pascals
ratio = 50:8 which can be represented as 50/8 which is 25/4 which can be written as 6.25:1
Hey, the answer is 12.5 : 1
The elephant has 4 legs not 1
Bruther.....first of all SI Unit of pressure is Newton/msq and not Newton/cmsq
so first you need to convert the cmsq into msq and then divide it by newtons....
second of all...the elephant has 4 legs and not 1 and the girl has 2 legs and not 1 so the answer would be 12.5:1
my bad

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

Because horse legs are so short but camel legs are so much longer than horse and in deserts attract the people in the soil
Because the surface area is less to horse then camel

Area - 250cm2
= 8

= 6.25:1 ans
it is 12.5/2 because girl has 2 legs and elephanthas 4 not 1
Ans is camel is having bigger feet than a horse which means the area of contact is more because the area of contact is more the pressure will be less. Horse's feet are smaller than that of a camel which means that area is less so pressure will be more thus the feet of the horse will go inside the sand
Hello
We use camels rather than horses as horse have small feet and exert more Pressure on sand hence they can't be used in deserts as they can't move while horses have padded feet which allow them to exert less pressure on sand
In the topic of muscular force on 4:26 sir showing his body💪🏻 😂😂
it is because camels have padded and broad feet which decreases the pressure acting upon the surface of the feet of the camel and the sand present in the desert.
It is difficult for a horse to walk in a dessert as compared to camel because foots of camels have big surface area than horse so the pressure of land will be less to it’s foot
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
1:22 starts video
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. 😊
Video starts at 1:19
Okie
Sir the horse 🐎 legs area is having less area which goes inside the sand and presure is high and the camels🐫 have big foot which have less pressure
A bad explanation , can explain a little more in detail
It is a revision video what do u think??
Camels hooves have more area than the hooves of horses. So the pressure acts on the horse's hooves more than the camel's hooves, resulting in the sinking of the horse, making it difficult to walk
