    The chemical symbol N stands for what element on the periodic table?

    • Nickel

    • Nitrogen

    • Neodymium

    • Neptumium

    • Nobelium

    Correct Answer
    A. Nitrogen
    Explanation
    The chemical symbol N stands for the element Nitrogen on the periodic table. Nitrogen is a nonmetallic element that is essential for life and makes up about 78% of Earth's atmosphere. It is commonly used in fertilizers, explosives, and various industrial processes. The symbol N was derived from the Latin word "nitrogenium" and is used internationally to represent this element.

    A fire needs heat and fuel to burn. What else does it need?

    • Water

    • Sand

    • Wood

    • Oxygen

    • A fire place

    Correct Answer
    A. Oxygen
    Explanation
    Oxygen is necessary for a fire to burn because it acts as an oxidizer, allowing the fuel to undergo combustion. Without oxygen, the fire cannot sustain itself and will eventually extinguish. Heat and fuel are also essential components for a fire, but without oxygen, the fire cannot continue to burn. Water, sand, and a fire place do not provide the necessary oxygen for combustion, so they are not correct answers.

    What is the definition of a hypothesis?

    • A educated guess

    • Something you use to cook

    • A way to measure temperature

    • A part of your body

    • A way to build a structure

    Correct Answer
    A. A educated guess
    Explanation
    A hypothesis is an educated guess because it is a proposed explanation or prediction based on prior knowledge and observations. It is a tentative statement that can be tested and verified through experimentation or further research. A hypothesis is not something you use to cook, measure temperature, a part of your body, or a way to build a structure.

    What is the name of the angle that is greater than 0 degrees but smaller than 90 degrees?

    • Right angle

    • Acute angle

    • Obtuse angle

    • Hypothesis Angle

    • Left angle

    Correct Answer
    A. Acute angle
    Explanation
    An acute angle is the name given to an angle that is greater than 0 degrees but smaller than 90 degrees. It is a type of angle that is smaller than a right angle and larger than a zero angle.

    What is Kinetic energy?

    • Stored energy

    • Motionless energy

    • Energy of Motion

    • Energy from the sun

    • Energy from the Earth's temperatures

    Correct Answer
    A. Energy of Motion
    Explanation
    Kinetic energy is the energy possessed by an object due to its motion. It is directly proportional to the mass and square of the velocity of the object. When an object is in motion, it has the ability to do work and transfer energy to other objects. Therefore, the correct answer is "Energy of Motion".

    Who invented the periodic table?

    • Dmitri Mendeleev

    • Neil Armstrong

    • Hilary Clinton

    • Albert Einstein

    • Thomas Edison

    Correct Answer
    A. Dmitri Mendeleev
    Explanation
    Dmitri Mendeleev is credited with inventing the periodic table. He was a Russian chemist who organized the elements based on their properties and atomic weights, creating a system that allowed for the prediction of undiscovered elements. Mendeleev's periodic table provided a framework for understanding and organizing the elements, and it has been widely used in the scientific community ever since its creation in 1869.

    How many natural satellites does Earth have?

    • 1

    • 2

    • 3

    • 4

    • 5

    Correct Answer
    A. 1
    Explanation
    Earth has one natural satellite, which is the Moon. The Moon orbits around the Earth and is the fifth-largest satellite in the solar system. It plays a significant role in various natural phenomena such as tides and the stabilization of Earth's rotation.

    How many picoseconds makeup one second?

    • 1

    • 1,000

    • 1,000,000

    • 1,000,000,000

    • 1,000,000,000,000

    Correct Answer
    A. 1,000,000,000,000
    Explanation
    One second is equivalent to 1,000,000,000,000 picoseconds. This is because a picosecond is a unit of time that is equal to one trillionth of a second. Therefore, when converting from seconds to picoseconds, we need to multiply by 1,000,000,000,000.
