Day 29: MH SSC Class 10 Science and Technology I

5 questions (7 parts). Try each one first, then open its answer.

  1. Question 1

    Gravitation. Asked once: Mar 2024 (same type asked 2 times)

    Q3(vii)
    The orbit of a satellite is exactly 35780 km above the earth's surface and its tangential velocity is 3.08 km/s. How much time the satellite will take to complete one revolution around the earth? (Radius of earth =6400= 6400 km.)

  2. Question 2

    Metallurgy. Asked once: Mar 2022 (same type asked 2 times)

    Answer the following:
    Q2(B)(iv)(b)
    What impurities are present in aluminium ore?

  3. Question 3

    Periodic Classification of Elements. Asked once: Mar 2025 (same type asked 2 times)

    Q3(ii)
    Write the name and symbol of the element from the description: (a) The most electronegative atom. (b) The atom having smallest atomic mass. (c) The noble gas with the smallest atomic radius.

  4. Question 4 (case study, 3 parts)

    Refraction of Light. Asked once: Mar 2019 (same type asked 2 times)

    Observations made by Swarali while doing experiments are given below. Based on these, write answers to the questions: Swarali found that a light ray travelling from a denser medium to a rarer medium goes away from the normal. If the angle of incidence (i) is raised by Swarali, the angle of refraction (r) went on increasing. However, after a certain value of the angle of incidence, the light ray is seen to return back into the denser medium.
    Q4(2)(i)
    What is the specific value of ∠i\angle i called?
    Q4(2)(ii)
    What is the process of reflection of the incident ray back into the denser medium called?
    Q4(2)(iii)
    Draw the diagrams of the three observations made by Swarali.

  5. Question 5

    Gravitation. Asked once: Mar 2019 (same type asked 2 times)

    Q3(1)
    What would be the value of 'g' on the surface of the earth if its mass were twice and its radius half of what it is now?
