    Which of the following is one of the sacred books of Buddhism?

    Solutions

    The correct answer is option 4 i.e. Tripitaka.

    The Tripitaka (also known as the Tipitaka in Pali) is the earliest and most revered collection of Buddhist teachings, considered canonical by Theravada Buddhists. Referred to as the Pali Canon, it is written in Pali, an ancient Indian language closely resembling the language spoken by the Buddha himself. This sacred text encompasses the foundational teachings, discourses, and rules of monastic conduct in Buddhism. Its preservation in Pali reflects its historical significance and serves as a fundamental source of spiritual guidance and doctrinal authority within the Theravada tradition.

    Who among the following was not the founding member of All India Muslim League?

    Solutions

    The Correct answer is Option 4 i.e Kamran Khan.

    • All India Muslim League was a political party established in 1906 in British India.
    • It was found as an alternative political group to the Indian National Congress
    • It's founding members include Aga Khan II, Khwaja Salimullah , Waqar UL mulk , Hakim Ajmal Khan and Muhammad Ali Jinnah.
  • Question 4/10
    1 / -0.33

    The _______ Movement was initiated by Subhas Chandra Bose after resigning from the Indian National Congress.

    Solutions

    The correct answer is Option 2 i.e. Forward Bloc.

    The Forward Bloc Movement was initiated by Subhas Chandra Bose after resigning from the Indian National Congress in 1939. Disillusioned with the Congress leadership's approach towards achieving independence, Bose established the Forward Bloc to consolidate the political left and unite all anti-imperialist forces. The movement aimed to mobilize the masses for complete independence from British rule and played a significant role in invigorating the Indian freedom struggle with its radical and uncompromising stance.

  • Question 5/10
    1 / -0.33

    Who is the author of the book "Junglee Nama"?

    Solutions

    The correct answer is Option 4 i.e. Amitava Ghosh.

    • Jungle Nama is Amitav Ghosh’s verse adaptation of an episode from the legend of Bon Bibi, a tale popular in the villages of the Sundarban. 
    • The original print version of this legend, dating back to the nineteenth century, is composed in a Bengali verse meter known as dwipodi poyar.
  • Question 6/10
    1 / -0.33

    A resistor has a resistance of 100 ohms and is connected to a 20-volt battery. What is the power dissipated by the resistor?

    Solutions

    The correct answer is Option 3 i.e. 4 W

    To find the power dissipated by a resistor, you can use the formula P = V2/R, where P is power,  V is voltage, and R is resistance. In this case, with a resistance of 100 ohms connected to a 20-volt battery, the calculation is as follows:

    P= 202/100= 400/100= 4W

    Thus, the power dissipated by the resistor is 4 W. This means that 4 watts of electrical energy is converted into heat.

  • Question 7/10
    1 / -0.33

    In a circuit with two resistors in series, if one has a resistance of 5 ohms and the other has 10 ohms, what is the total resistance?

    Solutions

    The correct answer is Option 4 i.e. 15 ohms.

    In a circuit with two resistors in series, the total resistance is the sum of the individual resistances. If one resistor has a resistance of 5 ohms and the other has 10 ohms, the total resistance can be calculated as follows:

    RTotal = R1 + R2 = 5Ω+ 10Ω = 15Ω

    Thus, the total resistance in this circuit is 15 ohms. This principle is fundamental in circuit analysis.

  • Question 8/10
    1 / -0.33

    Match the columns:

    Instruments:

    1. Voltmeter
    2. Ammeter
    3. Galvanometer
    4. Ohmmeter

    Descriptions:

    a. A device that measures the magnitude of electric current
    b. A device that measures voltage
    c. A device that measures resistance
    d. A device that measures the direction and magnitude of current

    Which description matches each instrument?

    Solutions

    The correct answer is option 1 i.e. Voltmeter - b, Ammeter - a, Galvanometer - d, Ohmmeter - c.

    The correct matches are:

    Voltmeter - b (A device that measures voltage)

    Ammeter - a (A device that measures the magnitude of electric current)

    Galvanometer - d (A device that measures the direction and magnitude of current)

    Ohmmeter - c (A device that measures resistance)

  • Question 9/10
    1 / -0.33

    If the magnetic field through a loop of wire is increasing, what happens to the induced electromotive force (EMF) in the loop?

    Solutions

    The correct answer is option 3 i.e. The EMF increases.

    • Faraday’s Law states that a change in the magnetic field through a loop induces an EMF in the loop. An increasing magnetic field induces a greater EMF.
    • As the magnetic field through a loop increases, the rate of change of magnetic flux increases, and consequently, the induced EMF in the loop also increases.
    • This relationship is a direct result of Faraday’s Law of Induction and is fundamental to the operation of many electrical devices and systems that rely on electromagnetic induction.
  • Question 10/10
    1 / -0.33

    The SI unit of radioactivity, representing the activity of a quantity of radioactive material, is named after which scientist?

    Solutions

    The correct answer is Option 3 i.e. Becquerel.

    The SI unit of radioactivity, representing the activity of a quantity of radioactive material, is named after Henri Becquerel, a French physicist who discovered radioactivity in 1896. The unit is called the "becquerel" (Bq), defined as one radioactive decay event per second. It quantifies the rate of radioactive decay in a substance. This unit honors Becquerel's pioneering work in the field of radioactivity, which laid the foundation for further research in nuclear physics and medicine.
