How do you strengthen a magnet? Place your weak magnet within the magnetic field of a much stronger magnet. Setting it right next to the magnet will produce the best result. The stronger magnet will actually help realign electrons that have spun out of axis since it’s creation. Stroke the weak magnet with your larger, […]

How can an object accelerate towards the center without getting closer to the center? If an object is in uniform circular motion, then it is accelerating towards the center of the circle; yet the object never gets any closer to the center of the circle. It maintains a circular path at a constant radius from […]

What are three properties of acids? Acids Aqueous solutions of acids are electrolytes, meaning that they conduct electrical current. Acids have a sour taste. Acids change the color of certain acid-base indicates. Acids react with active metals to yield hydrogen gas. Acids react with bases to produce a salt compound and water. How many types […]

What are the reasons for melting of a fuse wire? Answer. Answer: A fuse is used in a circuit to avoid overloading or short circuiting. When a current higher than the rating of the fuse flows through it, the fuse wire gets heated and melts. Why should a material of low melting point be used […]

Can a smartphone last 10 years? Can a smartphone last 10 years? “Hardware could operate for five to ten years,” says Clapp. Or, if you’ve kept it in good condition, you might want to sell your old phone on eBay; even if it’s not in good condition, you may be able to score a deal […]

Is April too late for frog spawn? Frogs usually emerge from hibernation at the beginning of March – though in some years they may put in an appearance even earlier – and spawning takes place from March through into April. Why do frogs attach to fish? There are so many that they block up his […]

What makes an eco resort Eco? Essentially, an eco-friendly or environmentally friendly hotel is one that is built or operated in such a way as to minimise both the carbon footprint of the business operation as well as the carbon footprint of those who work and stay there. Why eco-friendly products are important in hotel […]

How does covalent bonding affect melting point? Covalent compounds have bonds where electrons are shared between atoms. Due to the sharing of electrons, they exhibit characteristic physical properties that include lower melting points and electrical conductivity compared to ionic compounds. What type of bonding has the lowest melting point? Covalent Molecules Which bond is strongest […]

What are the three steps in the control process? Steps Involved in Control Process – Establishing Standards, Measuring Performance, Performance Appraisal and Correcting the Deviations. Basically the process of control involves three steps i.e.- (i) setting up standards (ii) performance appraisal and (iii) corrective measures. What are the 3 types of control? Three basic types […]

What does it mean if a circuit is in steady state? In electronics, steady state is an equilibrium condition of a circuit or network that occurs as the effects of transients are no longer important. Steady state is reached (attained) after transient (initial, oscillating or turbulent) state has subsided. Why does a capacitor act as […]
