    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
    @aryamankaushik6864 Před 4 měsíci +13

    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.

    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 😅

    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

  • @shauryadhanekar

    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

  • @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

  • @randomguy-nx8rx
    @randomguy-nx8rx Před dnem

    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

    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
      @fardheennissar3654 Před 4 měsíci +1

      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 .

    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

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

  • @NishaMahendra-t5t
    @NishaMahendra-t5t Před 23 dny

    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

    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. 😊

    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

  • @AbhishekSingh-lc9ji
