This process allows them to adapt to different environments and fulfill their ecological roles.

    A. Sekrup
    Explanation
    The principle of inclined plane is applied to the screw. The screw is a simple machine that consists of an inclined plane wrapped around a cylindrical shaft. When the screw is rotated, it moves through a material, allowing it to be easily inserted or extracted. The inclined plane of the screw allows for a greater force to be applied over a longer distance, making it an efficient tool for lifting or fastening objects.

    Inti bumi mempunyai panas sekitar

    • 5000 C

    • 4500 C

    • 4000 C

    • 3500 C

    Correct Answer
    A. 4500 C
    Explanation
    The correct answer is 4500 C. The Earth's core is estimated to have a temperature of around 4500 degrees Celsius. This high temperature is due to the heat generated by the radioactive decay of elements such as uranium and thorium, as well as the residual heat from the planet's formation. The core's extreme heat plays a crucial role in driving the convection currents that generate the Earth's magnetic field and power geological processes such as plate tectonics.
