What is the strength force DC? In the comics, the Strength Force is a cosmic force based around gravity and the force of motion. Its conduits are imbued with its powers by being enveloped by the Earth itself, acting as a sort of cocoon that causes them to undergo a rebirth. Who uses the strength […]

Is Sine a pendulum wave? Similar to what was observed for the mass on a spring, the position of the pendulum bob (measured along the arc relative to its rest position) is a function of the sine of the time. Is a pendulum sin or cos? The left/right part of a circle is a cosine […]

Why is a butterfly symmetrical? The line of symmetry is the imaginary line that divides something into two exactly equal and opposite parts. These two parts mirror each other; you can fold the figure in half and the two parts match exactly. Finish each butterfly so that one half matches the other, making them symmetrical. […]

What is the vision pathway? As visual information exits the occipital lobe, and as sound leaves the phonological network, it follows two main pathways, or “streams”. The ventral stream (also known as the “what pathway”) leads to the temporal lobe, which is involved with object and visual identification and recognition. How does the retina communicate […]

Can you lift or push a book lying on a table without touching it? We cannot push or lift a book lying on a table without touching it due to no interaction of objects because in performing these tasks we use muscular force. Since muscular force can be applied only when it is in contact […]

How do you know if an R group is polar or nonpolar? Just a recap, if you have on the end a Hydroxyl group, so OH. You have an Amino group, like an NH2, or you have a Sulfhydryl group, like an SH group on the end, then that would tell you that you have […]

How much does a differential cost? A typical rear differential repair costs anywhere between $200 and $400. These typical repairs would include your bearing, seals, and fluid changes. Of course, when a gear change is required, that’s when things get pricey. $1,500 is just the minimum you can expect to pay for new gears. What […]

Can we separate gravel sand and sugar? The sugar would dissolve in water. You could then pour off the solution and wash the remaining sand with a bit more water. Heat the water to evaporate it from the sugar, and the two are separated. How do you separate a sugar solution? The mixture of sugar-salt […]

How do you tell if a photon is emitted or absorbed? The color of the light emitted would result from the amount of energy as it moves through shells. Absorption is shown by the energy levels increasing as the photon gains energy. The wavelengths shown relate to the amount of energy in the photon. Can […]

How do you choose data for a graph? Choosing a graphing style by data type When comparing values, use column, bar, line and scatter-plot charts. When showing the distribution of data, use scatter-plot, line, column and bar charts. When analyzing trends in data, use line and column charts. How do you create a rank chart? […]
