What is the rate of change on a graph? A rate of change relates a change in an output quantity to a change in an input quantity. The average rate of change is determined using only the beginning and ending data. See (Figure). Identifying points that mark the interval on a graph can be used […]

Is biome a ecosystem? A biome is a large region of the world that has similar plants, animals and other organisms that are adapted to the terrain and weather of that region. An ecosystem is the interaction of plants and animals with nonliving things and each other. Is ecosystem bigger than community? The population, which […]

What is meant by components of velocity? Determining the Components of a Velocity Vector The two parts of a vector are known as components and describe the influence of that vector in a single direction. If a projectile is launched at an angle to the horizontal, then the initial velocity of the projectile has both […]

How do you convert C to F fast? If you find yourself needing to quickly convert Celsius to Fahrenheit, here is a simple trick you can use: multiply the temperature in degrees Celsius by 2, and then add 30 to get the (estimated) temperature in degrees Fahrenheit. How do you calculate C to F? To […]

How do the equations y MX and Y KX compare? We can compare y = kx to the slope-intercept form of a line, y = mx + b. We can see that y = kx is a linear equation with slope k and y-intercept 0. This tells us that the graph of a direct variation […]

What happens when two neutral charged objects are rubbed together? When an atom has an equal number of protons and electrons, the charges cancel each other and the atom is said to be neutral. Rubbed together in a dry environment, some items have lost electrons and become positively charged, while others have gained electrons and […]

How do you analyze timbre? There are many ways to analyse timbre. Some of the components we might describe include: The strength of the note’s harmonics, and how these change over time (think of a muted trumpet, or wah-wah guitar) Overtones and noise components (including clicks, scrapes and breaths) What is the difference between tone […]

What type of epithelial tissue looks stratified but is not? Pseudostratified columnar epithelium is a type of epithelium that appears to be stratified but instead consists of a single layer of irregularly shaped and differently sized columnar cells. In pseudostratified epithelium, nuclei of neighboring cells appear at different levels rather than clustered in the basal […]

What is the effect of changing temperature on the pressure? As the temperature increases, the particles move faster, and therefore have greater speeds, so greater momentum and therefore greater force when they collide with the walls, so the pressure increases. What is the relationship between air pressure and temperature? Air pressure is influenced by temperature […]

Is a guitar string a standing wave? A guitar string sound consists of standing waves: the fundamental and overtones. The fundamental wavelengh is twice the length of the vibrating part of the string. What type of wave does a guitar make? Longitudinal Waves What is the frequency of low E on a guitar? 82 Hz […]
