Are hot crusts more or less dense? It can get quite hot deep in the Earth’s crust. In fact, it can get so hot that the rocks that make up the crust can actually begin to melt. This molten material is called magma. It is less dense than the surrounding rock so it tends to […]

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 […]

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 […]

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 […]
