At what rate is the area of the triangle changing when the legs are m long? When the legs are 4 m long, the area of the triangle is changing at a rate of m^2/s. At what rate is the angle of elevation change? So the rate of change of the angle of elevation when […]
What actually happens during the total eclipse?
What actually happens during the total eclipse? A total eclipse occurs when the dark silhouette of the Moon completely obscures the intensely bright light of the Sun, allowing the much fainter solar corona to be visible. During any one eclipse, totality occurs at best only in a narrow track on the surface of Earth. This […]
How do you find the current in a loop?
How do you find the current in a loop? The loop equation can be used to find the current through the loop: I=VR1+R2+R3=12.00V1.00Ω+2.00Ω+3.00Ω=2.00A. Is current the same in a loop? If you have a circuit with a single loop, the current in every element is the same. In a single-loop circuit, all the elements are […]
What does the wave function ψ represent?
What does the wave function ψ represent? The wave function is a complex-valued probability amplitude, and the probabilities for the possible results of measurements made on the system can be derived from it. The most common symbols for a wave function are the Greek letters ψ and Ψ (lower-case and capital psi, respectively). What would […]
Is NADP+ a final electron acceptor?
Is NADP+ a final electron acceptor? The final electron acceptor is NADP. In oxygenic photosynthesis, the first electron donor is water, creating oxygen as a waste product. Cyclic phosphorylation is important to create ATP and maintain NADPH in the right proportion for the light-independent reactions. What is the final electron acceptor in photosynthesis and cellular […]
What is proper vector definition?
What is proper vector definition? Vector, in physics, a quantity that has both magnitude and direction. It is typically represented by an arrow whose direction is the same as that of the quantity and whose length is proportional to the quantity’s magnitude. Although a vector has magnitude and direction, it does not have position. What […]
What is the resistance and current through a 60W light bulb?
What can you see with 400X microscope?
What can you see with 400X microscope? At 400x magnification you will be able to see bacteria, blood cells and protozoans swimming around. At 1000x magnification you will be able to see these same items, but you will be able to see them even closer up. Which microscope is more powerful? electron microscope What is […]
What are three examples of acceleration?
What are three examples of acceleration? Examples An object was moving north at 10 meters per second. An apple is falling down. Jane is walking east at 3 kilometers per hour. Tom was walking east at 3 kilometers per hour. Sally was walking east at 3 kilometers per hour. Acceleration due to gravity. What is […]
What happens when you bring a compass near a magnet?
What happens when you bring a compass near a magnet? Notice that when the magnet is absent, the compass needle points north, but when the magnet is present, the needle points toward the magnet. This is because the compass needle is magnetized and mounted in a way that allows it to move in response to […]
