    • Potential- Energy at rest Kinetic- Energy at motion

    • Potential- Energy at motion Kinetic- Energy at rest

    Correct Answer
    A. Potential- Energy at rest Kinetic- Energy at motion
    Explanation
    Potential energy is the energy that an object possesses due to its position or condition. It is the energy that is stored and available to be converted into other forms of energy. When an object is at rest, it has potential energy. On the other hand, kinetic energy is the energy possessed by an object due to its motion. When an object is in motion, it has kinetic energy. Therefore, the correct answer is "Potential- Energy at rest, Kinetic- Energy at motion."

    Give at least one clue of chemical reaction/change.

    • Formation of bubbles

    • Freezing

    • Melting

    Correct Answer
    A. Formation of bubbles
    Explanation
    The formation of bubbles is a clue of a chemical reaction or change. When bubbles are formed, it indicates the release of gas, which is often a result of a chemical reaction. This can occur due to the decomposition of a compound, the reaction between two substances, or the release of gas as a byproduct. Bubbles can also be formed when a liquid is heated, causing it to vaporize and release gas. Therefore, the formation of bubbles is a clear indication of a chemical reaction or change taking place.

    Nuclear Energy comes mainly from:

    • Uraniun

    • Uranium

    • Coal

    • Fire

    Correct Answer
    A. Uranium
    Explanation
    Nuclear energy primarily comes from uranium. Uranium is a radioactive element that undergoes nuclear fission, a process in which its atomic nucleus splits into smaller parts, releasing a tremendous amount of energy. This energy is harnessed in nuclear power plants to generate electricity. Uranium is a commonly used fuel in nuclear reactors due to its high energy density and abundance. Coal and fire are not sources of nuclear energy; they are used in other forms of energy production such as thermal power plants.

    The Law of conservation of energy says that:

    • Energy can only be conserved not made nor destroyed

    • Energy can only be made and destroyed.

    • Energy can only be transformed, not made nor destroyed

    Correct Answer
    A. Energy can only be transformed, not made nor destroyed
    Explanation
    The correct answer is "energy can only be transformed, not made nor destroyed." This is based on the Law of Conservation of Energy, which states that energy can neither be created nor destroyed, but it can only change from one form to another. This principle is also known as the First Law of Thermodynamics. It means that the total amount of energy in a closed system remains constant, although it can be converted from one form to another, such as from potential energy to kinetic energy or from electrical energy to thermal energy.

    The nitrogen in the atmosphere can be transformed into ________________ by nitrogen fixing bacteria.

    Correct Answer
    ammonia
    nitrate
    Explanation
    Nitrogen fixing bacteria have the ability to convert atmospheric nitrogen into ammonia and nitrate. These bacteria have enzymes called nitrogenases that can break the strong triple bond between nitrogen atoms, allowing them to combine with hydrogen to form ammonia (NH3). Ammonia can then be further converted into nitrate (NO3-) through a process called nitrification, which is also carried out by certain bacteria. Therefore, both ammonia and nitrate can be produced by nitrogen fixing bacteria from atmospheric nitrogen.

    What are the two main things that power up the water cycle?

    • Gravity

    • Water

    • Sun

    Correct Answer(s)
    A. Gravity
    A. Sun
    Explanation
    The water cycle is powered by two main factors: gravity and the sun. Gravity plays a crucial role in the water cycle as it pulls water down from the atmosphere back to the Earth's surface, causing precipitation. The sun provides the energy needed for the water cycle to occur. It heats the Earth's surface, causing evaporation of water from bodies of water, plants, and soil. This evaporated water then rises into the atmosphere, where it cools and condenses to form clouds. Eventually, the condensed water droplets fall back to the Earth as precipitation, completing the water cycle.

    All electromagnetic radiations travel at an estimated speed of:

    • 300000 meters per second

    • 300000000 km/second

    • 300000000 m/second

    Correct Answer
    A. 300000000 m/second
    Explanation
    The correct answer is 300000000 m/second. This is because all electromagnetic radiations, including visible light, radio waves, and X-rays, travel at the same speed in a vacuum, which is approximately 300000000 meters per second. This speed is often referred to as the speed of light and is a fundamental constant in physics.

    Examples of Non- renewable sources?

    • Biomass

    • Coal

    • Nuclear Plants

    • Geothermal

    • Hot spring

    • Radiation

    Correct Answer(s)
    A. Coal
    A. Nuclear Plants
    Explanation
    The correct answer is Coal and Nuclear Plants. Both coal and nuclear plants are examples of non-renewable sources of energy. Coal is a fossil fuel that is formed from the remains of plants that lived and died millions of years ago. It is extracted from the earth and burned to generate electricity. However, coal is a finite resource and its combustion releases harmful pollutants into the atmosphere. Nuclear plants, on the other hand, use nuclear reactions to produce energy. They rely on uranium, a non-renewable element, as fuel. The process involves splitting uranium atoms, which releases a large amount of energy. However, uranium is also a limited resource, and the waste produced by nuclear plants is highly radioactive and requires careful disposal.
