How do you increase the force of a wire? If the current-carrying wire is placed in a magnetic field (whose lines of force are at right angles to the wire) then it will experience a force at right angles to both the current direction and the magnetic field lines. The force increases if the strength […]

How long does it take for an ice cube to melt in boiling water? 90 to 120 minutes Does boiling hot water damage car paint? Using boiling water on the car part is just as likely to cause further damage, which will only increase the cost of repair. Can I pour warm water on my […]

Why do oppositely charged particles have to attract repel each other? The two charges repel each other. If a positive charge and a negative charge interact, their forces act in the same direction, from the positive to the negative charge. As a result opposite charges attract each other: The electric field and resulting forces produced […]

What is the 2 meter calling frequency? For new hams who are likely to get started in local VHF/UHF operation, the national calling frequencies to be concerned with are 2m and 70cm FM simplex (non-repeater). These are 146.520MHz and 446.000MHz, respectively, and should be included in your radio’s scanned channels. What frequency is 70 cm? […]

Why zinc is not a transition metal? A transition metal is one that forms one or more stable ions which have incompletely filled d orbitals. On the basis of this definition, scandium and zinc do not count as transition metals – even though they are members of the d block. The zinc ion has full […]

What is the resolving power of an electron microscope? Since the wavelength o f electrons are 100,000 times shorter than visible light the electron microscopes have greater resolving power. They can achieve a resolution of 0.2nm and magnifications upto 2,000,000 x. Light microscopes show limited resolution than electron microscopes. Which lens has the greatest resolving […]

How can you tell if your well is low? The first sign is the water is sputtering out of the tap, indicating air pockets in the well. The second sign is the water is not clear, but muddy or filled with sediment. How long does well water take to refill? It’s difficult to give a […]
