What do Isometries preserve? An isometry is a transformation that preserves the relative distance between points. Under an isometry, the image of a point is its final position. What are the four types of Isometries? There are four types: translations, rotations, reflections, and glide reflections (see below under classification of Euclidean plane isometries). The set […]
What two forces limit the height of capillary action will take water up a tube?
What two forces limit the height of capillary action will take water up a tube? Capillary action occurs when the adhesion to the walls is stronger than the cohesive forces between the liquid molecules. The height to which capillary action will take water in a uniform circular tube (picture to right) is limited by surface […]
What plant and animal cells have in common?
What plant and animal cells have in common? Animal cells and plant cells share the common components of a nucleus, cytoplasm, mitochondria and a cell membrane. Plant cells have three extra components, a vacuole, chloroplast and a cell wall. What is unique to plant cells? The plant cell has a cell wall, chloroplasts, plastids, and […]

What is the types of igneous rock?
What is the types of igneous rock? The two main categories of igneous rocks are extrusive and intrusive. Extrusive rocks are formed on the surface of the Earth from lava, which is magma that has emerged from underground. Intrusive rocks are formed from magma that cools and solidifies within the crust of the planet. What […]
What is the mechanism of action of risperidone?
What is the mechanism of action of risperidone? Risperidone is an SGA with a high 5-HT2A/D2 ratio (it has a higher affinity for 5-HT2A receptors than for D2 receptors). According to the dopamine theory of schizophrenia, the mechanism of action of risperidone might involve a reduction of dopaminergic neurotransmission in the mesolimbic pathway. Is 2 […]

Does lift increase with speed?
Does lift increase with speed? Drag versus speed. method of increasing lift is by increasing velocity if the AOA is held constant just short of the “critical,” or stalling, AOA (assuming no flaps or other high lift devices). Lift and drag also vary directly with the density of the air. Does lift increase with Reynolds […]
