What is H in Maxwell equations? The four Maxwell equations, corresponding to the four statements above, are: (1) div D = ρ, (2) div B = 0, (3) curl E = -dB/dt, and (4) curl H = dD/dt + J. Read More on This Topic. light: Maxwell’s equations. In the early 1860s, Maxwell completed a […]

Is burning of candle a reversible change?
Is burning of candle a reversible change? When a candle is burned, chemical reactions take place between the wax and oxygen. These chemical reactions release energy in the form of heat and light. These chemical reactions can’t be reversed back. What ways to change the materials? What are some ways of changing solid materials? Physical […]
Why is evaporation important how can it help you?
Why is evaporation important how can it help you? The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor. Evaporation is a very important part of the water cycle. Heat from the sun, or solar energy, powers the evaporation process. Once water evaporates, it also helps form […]
Which forest layer has the greatest amount of net primary productivity?
Which forest layer has the greatest amount of net primary productivity? Basic ideas – NPP in terrestrial ecosystems Tropical rain forests have high NPP and the highest biodiversities of any terrestrial ecosystems. The physical environment favours vast photosynthetic output and high growth rate. Which biomes are most affected by humans? Tropical dry forests and temperate […]
How much energy is used in photosynthesis?
How much energy is used in photosynthesis? The part of the solar spectrum used by plants has an estimated mean wavelength of 570 nm; therefore, the energy of light used during photosynthesis is approximately 28,600/570, or 50 kcal per einstein. What percentage of sunlight is used in photosynthesis? 3 percent What organisms use energy for […]
What is the maximum potential energy of the spring?
What is the maximum potential energy of the spring? When the kinetic energy is maximum, the potential energy is zero. This occurs when the velocity is maximum and the mass is at the equilibrium position. The potential energy is maximum when the speed is zero. What is the potential energy of a spring derive it? […]
What is a chain reaction simple definition?
What is a chain reaction simple definition? 1a : a series of events so related to each other that each one initiates the next. b : a number of events triggered by the same initial event. 2 : a self-sustaining chemical or nuclear reaction yielding energy or products that cause further reactions of the same […]
What element has 2 protons 2 neutrons?
What element has 2 protons 2 neutrons? Helium What did Chadwick prove? In 1932, Chadwick made a fundamental discovery in the domain of nuclear science: he proved the existence of neutrons – elementary particles devoid of any electrical charge. For this epoch-making discovery he was awarded the Hughes Medal of the Royal Society in 1932, […]
What are the two main functions of cell wall?
What are the two main functions of cell wall? The main function of the cell wall is to provide structural strength and support, and also provide a semi-permeable surface for molecules to pass in and out of the cell. Where are cell walls found? A cell wall is a fairly rigid layer surrounding a cell […]
