Why does Lake Tahoe not freeze?
Why does Lake Tahoe not freeze? The main body of Lake Tahoe does not freeze. The stored heat in the Lake’s massive amount of water compared to its relative surface area prevents the Lake from reaching freezing temperature under the prevailing climatic conditions. Why surface of lake is frozen? Explanation: In order for water to […]

How do you solve an unbalanced bridge?
How do you solve an unbalanced bridge? The unbalanced Wheatstone bridge can be solved using Kirchhoff’s Current Law and Kirchhoff’s Voltage Law. How is bridge resistance calculated? Wheatstone bridge circuit diagram. The unknown resistance Rx is to be measured; resistances R1, R2 and R3 are known, where R2 is adjustable. When the measured voltage VG […]
What is the oldest candy?
What is the oldest candy? The Chocolate Cream bar created by Joseph Fry in 1866 is the oldest candy bar in the world.

Why is the final velocity 0?
Why is the final velocity 0? People mistakenly think the final velocity for a falling object is zero because objects stop once they hit the ground. In physics problems, the final velocity is the speed just before touching the ground. Once it touches the ground, the object is no longer in freefall. Can a 50 […]
Why do I keep smelling ozone?
Why do I keep smelling ozone? Some people can smell ozone before the storm has even arrived.

This can ultimate result in a small amount of ozone forming, which wind then carries down to ground level. What […]
What happens to a positron after its creation?
What happens to a positron after its creation? For pair production to occur, the electromagnetic energy, in a discrete quantity called a photon, must be at least equivalent to the mass of two electrons. The positron that is formed quickly disappears by reconversion into photons in the process of annihilation with another electron in matter. […]
