Answer the following question given this paragraph: Solutions to Schrodinger's equation involve four special numbers called quantum numbers . (Three of the numbers, , , and , come from Schrodinger's equation, and the fourth one comes from an extension of the theory). These four numbers completely describe the energy of an electron. Each electron has exactly four quantum numbers, and no two electrons have the same four numbers. The statement that no two electrons can have the same four quantum numbers is known as the Pauli exclusion principle . Q: Solutions to schrodinger's equation involve four special numbers called what? Choices: - gravity numbers - linear numbers - light numbers - quantum numbers A:
quantum numbers

Answer the following question given this paragraph: You couldn't survive without your skin. It has many important functions. In several ways, it helps maintain homeostasis. The main function of the skin is controlling what enters and leaves the body. It prevents the loss of too much water from the body. It also prevents bacteria and other microorganisms from entering the body. Melanin in the epidermis absorbs ultraviolet light. This prevents the light from reaching and damaging the dermis. Q: What is the largest organ of the human body? Choices: - your lungs - your brain - your blood - your skin A:
your skin

Answer the following question given this paragraph: Heat is the transfer of thermal energy between substances. Thermal energy is the kinetic energy of moving particles of matter, measured by their temperature. Thermal energy always moves from matter with greater thermal energy to matter with less thermal energy, so it moves from warmer to cooler substances. You can see this in the Figure below . Faster-moving particles of the warmer substance bump into and transfer some of their energy to slower-moving particles of the cooler substance. Thermal energy is transferred in this way until both substances have the same thermal energy and temperature. For a visual introduction to these concepts, watch the animation "Temperature vs. Heat" at this URL:. Q: Kinetic energy of moving particles of matter, measured by their temperatures are known as: Choices: - visible energy - atmospheric energy - solar energy - thermal energy A:
thermal energy

Answer the following question given this paragraph: Primary Batteries Primary batteries are single-use batteries because they cannot be recharged. A common primary battery is the dry cell (Figure 17.10). The dry cell is a zinc-carbon battery. The zinc can serves as both a container and the negative electrode. The positive electrode is a rod made of carbon that is surrounded by a paste of manganese(IV) oxide, zinc chloride, ammonium chloride, carbon powder, and a small amount of water. The reaction at the anode can be represented as the ordinary oxidation of zinc: Zn(s) Zn 2+(aq) + 2e . Q: Primary batteries are single-use batteries because they cannot be what? Choices: - UP ticked. - refreshed - plugged - recharged A:
recharged
