Is the parent or daughter radioactive? Radioactive Isotopes The radioactive decay of a parent isotope (the original element) leads to the formation of stable daughter product, also known as daughter isotope. As time passes, the number of parent isotopes decreases and the number of daughter isotopes increases (Figure below). Which method is used to date […]
Do wind turbines increase global warming?
Do wind turbines increase global warming? The conversion of wind energy to electricity does not release greenhouse gases and so does not contribute to global warming. Small amounts of greenhouse gases are released during the manufacturing and transportation of the wind turbines to their installation site. Do windmills cause global warming? A study published today […]
What causes a resistor to become non ohmic?
What causes a resistor to become non ohmic? As more current flows through a resistor, it generates more and more heat. This heat, when it becomes excessive, can cause the resistor to become non-Ohmic and the resistance would also increase. Even ordinary wires are also considered as Ohmic conductors. Are capacitors resistors? Capacitor vs Resistor […]
What is use of electromagnet Class 7?
What is use of electromagnet Class 7? An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. The magnetic field disappears when the current is turned off. Electromagnets usually consist of a large number of closely spaced turns of wire or coilthat create the magnetic field. What […]
Is Piano easier than guitar?
Is Piano easier than guitar? Granted, the piano does become tricky later on when you start to play rhythmically independent notes between different fingers and hands. With guitar, playing tends to get easier over time as students often grasp chords and learn several songs faster than a piano student might. Which instrument is hardest to […]
What does a steep line in a distance time graph show?
What does a steep line in a distance time graph show? A sloping line on a distance-time graph shows that the object is moving. The steeper the line (and the greater the gradient) the faster the object is moving. Calculate the speed of the object represented by the green line in the graph, from 0 […]
What are the six properties of liquids?
What are the six properties of liquids? Properties of Liquids Capillary Action. Cohesive and Adhesive Forces. Contact Angles. Surface Tension. Unusual Properties of Water. Vapor Pressure. Viscosity Viscosity is another type of bulk property defined as a liquid’s resistance to flow. Wetting Agents. What are three properties of liquids? 1 Answer Liquids are almost incompressible. […]
How do you calculate bonding pairs?
How do you calculate bonding pairs? Count the number of atoms bonded to the central atom and multiply by 8 to account for full octets on all atoms involved; 2 bonded I atoms account for 16 valence electrons. There are three lone pairs (6/2) of electrons around the central atom. What are the bonding electrons? […]
Do magnets affect SSD?
Do magnets affect SSD? Magnets have no effect on SSDs except to the extent that a change in magnetic flux induces a current in wires. Though that probably won’t make cause noticeable effect. Presumably you’re asking whether you can erase a disk by waving a magnet over it. What can damage a SSD? It can […]
What biomolecule is bread and honey?
What biomolecule is bread and honey? Carbohydrates. Carbohydrates form the largest part of most peoples diets and is their main source of energy. Sugar is found in foods such as sweets, fruit & honey. Starch is found in rice, potatoes, bread, pasta etc. What are the major biomolecules? Biomolecule, also called biological molecule, any of […]
