    Which of these is a conditional energy?

    • Dirty Energy

    • Swamp Energy

    • Kinetic Energy

    • Potential Energy

    Correct Answer
    A. Potential Energy
    Explanation
    Potential energy is a type of energy that is associated with an object's position or state. It is stored energy that has the potential to be converted into other forms of energy, such as kinetic energy. Unlike dirty energy or swamp energy, which are not specific types of energy, potential energy is a well-defined concept in physics. Therefore, potential energy is the correct answer as it meets the criteria of being a conditional energy.

    What law describes resistances?

    • Resistor's Law

    • Current's Law

    • Meter's Law

    • Ohm's Law

    Correct Answer
    A. Ohm's Law
    Explanation
    Ohm's Law describes the relationship between resistance, current, and voltage in an electrical circuit. It states that the current flowing through a conductor is directly proportional to the voltage applied across it and inversely proportional to the resistance of the conductor. This law is named after the German physicist Georg Simon Ohm, who first formulated it in 1827.

    What do electricians use to test circuits?

    • Continuity Tester

    • Ruler

    • Circus Peanuts

    • Thermometer

    Correct Answer
    A. Continuity Tester
    Explanation
    Electricians use a continuity tester to test circuits. This device is used to check if there is an uninterrupted path for the flow of electric current in a circuit. It helps to identify any breaks or faults in the circuit by indicating whether there is continuity or a break in the electrical connection. A ruler is not used for testing circuits, and a thermometer is used to measure temperature, not to test circuits. Circus peanuts have no relevance to testing circuits.

    What are circuits that have only one path for electricity to flow?

    • Series Circuits

    • Piston Circuits

    • Parallel Circuits

    • Closing Circuits

    Correct Answer
    A. Series Circuits
    Explanation
    Series circuits are circuits that have only one path for electricity to flow. In a series circuit, the components are connected end to end, forming a single loop. This means that the current flowing through each component is the same. If one component in a series circuit fails or is removed, the entire circuit is broken and no current can flow. Therefore, series circuits are characterized by having a single path for electricity to flow.

    What measurement is defined as using one kilowatt in one hour?

    • Joule

    • Amp

    • Volt

    • Kilowatt-Hour

    Correct Answer
    A. Kilowatt-Hour
    Explanation
    A kilowatt-hour is the correct measurement for using one kilowatt in one hour. It is a unit of energy equal to the amount of energy used by a one-kilowatt device in one hour. This measurement is commonly used to determine electricity consumption and billing.

    Who defined the radius of a black hole?

    • Keppler

    • Schwartzchild

    • Hawking

    • Einstein

    Correct Answer
    A. Schwartzchild
    Explanation
    Schwartzchild is the correct answer because he was the first to provide a mathematical solution to Einstein's field equations that described the geometry of a black hole. This solution, known as the Schwartzchild metric, includes a parameter called the Schwartzchild radius, which defines the size of the event horizon of a black hole. Therefore, Schwartzchild defined the radius of a black hole through his metric.

    How many quarks make up a proton?

    • Trick Question - There Aren't Any Quarks In A Proton

    • One

    • Two

    • Three

    Correct Answer
    A. Three
    Explanation
    A proton is made up of three quarks. Quarks are elementary particles that are the building blocks of protons and neutrons. Protons consist of two up quarks and one down quark, which gives them a positive charge. The combination of these three quarks creates the overall structure and properties of a proton.

    Why does your voice sounds higher after you breathe helium?

    • Helium Only Propagates Sound Waves With A High Pitch

    • Helium Constricts Your Vocal Cords

    • It Actually Doesn't.. It's An Auditory Illusion

    • The Speed And Density Of Helium Compared To Air

    Correct Answer
    A. The Speed And Density Of Helium Compared To Air
    Explanation
    Helium has a lower density and higher speed of sound compared to air. When we inhale helium, it replaces the air in our vocal tract. The lower density of helium causes the sound waves to travel faster, resulting in a higher pitch when they reach our ears. This change in the speed and density of the medium through which the sound waves propagate leads to the auditory illusion of a higher voice.

    Which is not true of concave lenses?

    • They're Used To Correct Near-Sightedness

    • Their Focal Length Is Defined To Be Negative

    • They Only Produce Virtual Images

    • They're Useful As Magnifying Lenses

    Correct Answer
    A. They're Useful As Magnifying Lenses
    Explanation
    Concave lenses are used to correct near-sightedness, so the statement "They're Used To Correct Near-Sightedness" is true. The focal length of a concave lens is defined to be negative, which means that the lens diverges light rays. This is also true. Concave lenses only produce virtual images, as the light rays appear to diverge from a virtual focal point. Lastly, concave lenses are not useful as magnifying lenses, as they cause objects to appear smaller. Therefore, the statement "They're Useful As Magnifying Lenses" is not true.

    What circuit is put on a piece of chemically bathed plastic?

    • Plasticizers

    • Artificial Circuits

    • Printed Circuit

    • Ringed Circuit

    Correct Answer
    A. Printed Circuit
    Explanation
    A printed circuit is a circuit that is created by printing conductive material onto a piece of chemically bathed plastic. This allows for the creation of a compact and efficient circuit that can be easily mass-produced. Plasticizers are substances added to plastic to increase its flexibility, but they are not circuits themselves. Artificial circuits and ringed circuits are not commonly used terms in the context of circuitry.

    What is an area where atomic magnets point in the same direction called?

    • Domination

    • Domain

    • Mass Area

    • Atomical Point

    Correct Answer
    A. Domain
    Explanation
    A domain is an area where atomic magnets point in the same direction. In a material, the arrangement of atomic magnets determines its magnetic properties. When the atomic magnets align and point in the same direction within a specific region, it forms a domain. Domains are important in understanding how magnetic materials behave and interact with magnetic fields.

    Paul Dirac, in his relativistic treatment of quantum mechanics, predicted what elementary particle later observed by Carl Anderson?

    • Positrons

    • Muons

    • Quarks

    • Hadrons

    Correct Answer
    A. Positrons
    Explanation
    In his relativistic treatment of quantum mechanics, Paul Dirac predicted the existence of a new elementary particle. This particle, later observed by Carl Anderson, is known as a positron. Positrons are the antiparticles of electrons, carrying a positive charge instead of a negative charge. Dirac's prediction of the positron was a significant contribution to the field of particle physics and provided further evidence for the existence of antimatter.

    Albert Einstein received the 1921 Nobel Prize for formulating the theory that explained what phenomenon?

    • Special Relativity

    • General Relativity

    • Blackbody Radiation

    • Photoelectric Effect

    Correct Answer
    A. Photoelectric Effect
    Explanation
    Albert Einstein received the 1921 Nobel Prize for formulating the theory of the photoelectric effect. This theory explained the phenomenon of how light can eject electrons from a material's surface. Einstein's work on the photoelectric effect provided strong evidence for the particle-like behavior of light and laid the foundation for the development of quantum mechanics.

    Which of the following is NOT true of static magnetic fields?

    • They Are Spherically Symmetric

    • They Deflect Charged Particles

    • They Can Be Produced By Current Loops

    • They Can Do No Work

    Correct Answer
    A. They Are Spherically Symmetric
    Explanation
    Static magnetic fields are not spherically symmetric. Spherical symmetry means that the field has the same strength and direction at all points on a sphere centered on the source of the field. However, static magnetic fields have a specific direction and strength that can vary at different points in space, depending on the source of the field. Therefore, they do not exhibit spherical symmetry.
