Why does intensity decrease with distance? There is an inverse relationship between distance and light intensity – as the distance increases, light intensity decreases. This is because as the distance away from a light source increases, photons of light become spread over a wider area. How much louder is 70 dB to 50db? Yet that […]
What is chain reaction with example?
What is chain reaction with example? In chain reaction. Nuclear chain reactions are series of nuclear fissions (splitting of atomic nuclei), each initiated by a neutron produced in a preceding fission. For example, 21/2 neutrons on the average are released by the fission of each uranium-235 nucleus that absorbs a low-energy neutron. What is another […]
What are the three main types of body membranes?
What are the three main types of body membranes? There are three types of epithelial membranes: mucous, which contain glands; serous, which secrete fluid; and cutaneous which makes up the skin. What are the three functions of body membranes? Biological membranes have three primary functions: (1) they keep toxic substances out of the cell; (2) […]

Where is critical listening used?
Where is critical listening used? We can be said to be engaged in critical listening when the goal is to evaluate or scrutinise what is being said. Critical listening is a much more active behaviour than informational listening and usually involves some sort of problem solving or decision making. What is critical listening Where do […]
How do you calculate valve torque?
How do you calculate valve torque? Dynamic torque can be calculated from the formula Td = C (ΔP). Here, ΔP is the effective pressure drop across the valve at a given temperature and C is, once again, a constant. What is Torque valve? A torque-seated valve (e.g., gate valve) will use the torque switches to […]
Is powdered chocolate a solute?
Is powdered chocolate a solute? The solution of hot chocolate becomes one mixture rather than powder and water. The substance that is being dissolved in another substance is called the solute. In this example, the hot chocolate powder is the solute. Is chocolate powder dissolve in hot water easily? Explanation: Hot water has more energy […]
What is 10g LAN?
What is 10g LAN? 10 gigabit Ethernet is a telecommunication technology that offers data speeds up to 10 billion bits per second. 10 gigabit Ethernet (10-Gigabit Ethernet) is also known as 10GE, 10GbE or 10 GigE. The IEEE 802.3ae standard permits distances between physical locations up to 40 kilometers over a single-mode fiber. Who needs […]
Is there no noise in space?
Is there no noise in space? Unlike light, sound requires a medium to travel through. This simply means that in order to hear sound there has to be something for sound to travel through. In the vacuum of space, there are no (or very, very few) particles to vibrate, so sound cannot travel through this […]
