Do ponds freeze all the way through? Ponds freeze from the top down and very rarely freeze solid all the way through. When you see a frozen pond it is only ice capped which will slow down the oxygen intake and ammonia release of the pond, but it does not stop it. Should I break […]
How does adhesion play a role in surface tension?
How does adhesion play a role in surface tension? Surface Tension makes them bead up. Adhesion keeps them attached to the leaves instead of running off. Why is cohesion and adhesion important to life? Why are cohesive and adhesive forces important for life? Cohesive and adhesive forces are important for the transport of water from […]
Can you have causation without correlation?
Can you have causation without correlation? Causation can occur without correlation when a lack of change in the variables is present. Lack of change in variables occurs most often with insufficient samples. In the most basic example, if we have a sample of 1, we have no correlation, because there’s no other data point to […]
Are all waves spherical?
Are all waves spherical? All the waves come from a single point source and are spherical. Spherical Wave: When waves are produced from a point source, they are spherical waves. What is a spherical wave? [′sfir·ə·kəl ′wāv] (physics) A wave whose equiphase surfaces form a family of concentric spheres; the direction of travel is always […]
What type of collisions are there?
What type of collisions are there? There are three different kinds of collisions, however, elastic, inelastic, and completely inelastic. Just to restate, momentum is conserved in all three kinds of collisions. What distinguishes the collisions is what happens to the kinetic energy. What is the most common type of collision physics? There are two general […]
Is the image formed by a compound microscope real or virtual?
Is the image formed by a compound microscope real or virtual? With the compound microscope, this intermediate image is real, formed by the objective lens. In all cases, the function of the eyepiece is to form a virtual, magnified image for your eye to view. What kind of image does a compound microscope form? A […]
What is the difference between a continuous spectrum and a bright line spectrum?
What is the difference between a continuous spectrum and a bright line spectrum? The main difference between continuous spectrum and line spectrum is that line spectra can be seen as either isolated emission lines or absorption lines, with huge gaps between them, whereas continuous spectra do not contain gaps and can be produced by superimposing […]
How much can the flash lift?
How much can the flash lift? He says about 400lbs. So we know he can at least do that. Technically he can generate an infinite amount of momentum and hit things with any force. Is the speed force real? The Flash’s speed comes from the speed force, something that doesn’t actually exist in the observed […]
Is it OK to add water to soap?
Is it OK to add water to soap? Liquid soaps contain a very strict amount of preservatives which prevent bacteria from multiplying in the dispenser. When you open the dispenser and add tap water, you may be adding bacteria as well. Plus the extra water reduces the effectiveness of the preservatives, meaning the bacteria can […]
What does 42 mean?
