What are the name of the properties? Property (a, b and c are real numbers, variables or algebraic expressions) 1. Distributive Property a • (b + c) = a • b + a • c 2. Commutative Property of Addition a + b = b + a 3. Commutative Property of Multiplication a • b […]

Does UV light break down ozone? UV light will create ozone from atmospheric oxygen at short wavelengths of less than 240 nanometers (nm). UV light will also destroy ozone and break ozone back down into atomic oxygen (O) and diatomic oxygen (O2) at wavelengths from about 200 nm to 315 nm. How do you kill […]

Which is the healthiest sport? The 10 Healthiest Sports (1) Squash. Although squash players must be wary of flying racquets coming from their opponent’s direction, squash is a relatively safe game for beginners. (2) Rowing. (3) Rock Climbing. (4) Swimming. (5) Cross-Country Skiing. (6) Basketball. (7) Cycling. (8) Running. What are the positive and negative […]

How do I raise the pH in my pool without alkalinity? Use Aeration to Raise Pool pH (and not Alkalinity) You can’t, but you can raise pH without affecting Alkalinity. This is done by lowering the pH and Alkalinity with pH Decreaser, then raise the pH through aeration. Just add air! How do I fix […]

Do solar panels need to be cleaned? Your solar panels need to be exposed to sunlight in order to produce power. However, unless you live somewhere with high amounts of smog, dust, dirt or sand blowing around, solar panel cleaning is generally not necessary. Can you walk on solar panels? BUST – In theory you […]

What is E in drift velocity? In physics a drift velocity is the average velocity attained by charged particles, such as electrons, in a material due to an electric field. In general, an electron in a conductor will propagate randomly at the Fermi velocity, resulting in an average velocity of zero. Why is electron drift […]

What is the formula for displacement? Displacement (s) of an object equals, velocity (u) times time (t), plus ½ times acceleration (a) times time squared (t2). What is the area under displacement time graph? Important: The area between a velocity-time graph and the `time’ axis gives the displacement of the object. The slope is the […]

What are the three types of molecular models? Molecular models fall into three basic categories: ball-and-stick, skeletal, and space-filling. What are four types of molecular models? On this page: Ball and spoke models. Space-filling models. Crystal lattice models. What is the purpose of molecular models? Molecular modeling is rapidly growing according to its applications in […]

What are 2 types of cellular respiration? There are two main types of cellular respiration—aerobic respiration and anaerobic respiration. Aerobic respiration is a specific type of cellular respiration, in which oxygen (O2) is required to create ATP. What is the fundamental difference between photosynthesis and cellular respiration? What is the relationship between photosynthesis and cellular […]

What are two sides of a ray called? In plane geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. How do you name a 3 point line? Collinear is when you have three or more points on a […]
