What happens to the force when the distance is doubled? So as two objects are separated from each other, the force of gravitational attraction between them also decreases. If the separation distance between two objects is doubled (increased by a factor of 2), then the force of gravitational attraction is decreased by a factor of […]
Which type of reaction occurs in the core of a nuclear?
Which type of reaction occurs in the core of a nuclear? Nuclear reactors are the heart of a nuclear power plant. They contain and control nuclear chain reactions that produce heat through a physical process called fission. That heat is used to make steam that spins a turbine to create electricity. Why is it important […]
In which states can convection occur?
In which states can convection occur? Convection is the transfer of heat energy through the movement of fluid particles. Hence, convection cannot take place in solids, since the solid particles are not fluid. Thus, convection only takes place in liquids and gases. Where can you see convection in everyday life? 13 Examples Of Convection In […]
Do plants and animals have a rough ER?
Do plants and animals have a rough ER? Endoplasmic reticulum is an organelle found in both eukaryotic animal and plant cells. It often appears as two interconnected sub-compartments, namely rough ER and smooth ER. Both types consist of membrane enclosed, interconnected flattened tubes. What is the function of RER and SER? Difference between Smooth and […]
What is the least complex level of organization of the human body?
What is the least complex level of organization of the human body? Summarizing: The major levels of organization in the body, from the simplest to the most complex are: atoms, molecules, organelles, cells, tissues, organs, organ systems, and the human organism. What is the lowest level of organization in the nervous system? Cells are the […]
How can we find out near which end is North Pole located in a bar magnet?
How can we find out near which end is North Pole located in a bar magnet? Answer. Location of the poles of as magnet can be determined by suspending it freely. A freely suspended bar magnet always points in north−south direction. The end that points towards north direction is the north pole of the magnet […]
What is control and what are the six reasons control is needed?
What is control and what are the six reasons control is needed? (1) To Adapt to change and uncertainity. (2)To Discover Irregularities & Errors. (3) To Reduce costs, Increase Productivity, or Add Value. (4)To Detect Opportunities. (5) To Deal with Complexity. What is the first step of the control process? Controlling involves ensuring that performance […]
Why do you think groundwater investigation is important?
Why do you think groundwater investigation is important? The viability of groundwater sources and exploitation methods depend on the water quality. Therefore, investigation of groundwater quality and result assessment and interpretation are very important in deciding management policy. What is groundwater monitoring? Typical groundwater monitoring wells are used to enhance environmental protection at landfills. WM […]
Is nuclear binding energy positive or negative?
Is nuclear binding energy positive or negative? Nuclear binding energy is the energy required to split a nucleus of an atom into its component parts: protons and neutrons, or, collectively, the nucleons. The binding energy of nuclei is always a positive number, since all nuclei require net energy to separate them into individual protons and […]
Do phones cause headaches?
Do phones cause headaches? Long hours looking at television, computers, tablets, cell phones, and video games can lead to exhaustion, lack of circulation, and eyestrain, which can cause headaches. Rarely is eyestrain the sole cause of headaches. If we suspect that eyestrain is a problem, we may recommend an ophthalmological exam. Why do I get […]
