Why do some countries have 60hz frequency?
Technically there is little to choose between 50 and 60 Hz and it's just history that determined it. Once the choice is made it's difficult to change. The lower frequency is slightly better for long-distance transmission of power because the resistance of same-sized wires is slightly less. The higher frequency is slightly better because iron transformer cores can be made 20% lighter.
What is mercury made of composition?
There is no exact answer to this. Astronomers have estimated that the composition of Mercury is approximately 70 percent metals and 30 percent of silicate material. It is slightly less dense than earth.
What direction is a rainbow if the sun is setting?
If the sun is setting, then the center of the rainbow is to the east of you, and on or slightly below the horizon ... directly opposite the sun.
In sound waves do compression waves move faster than rarefaction waves?
sorta, compressions move at a slightly higher frequency, which is indirectly related to speed.
How does frequency relate to pitch of a sound wave?
The higher the frequency, the higher the pitch. The lower the frequency, the lower the pitch.
What is the opposite of slightly?
The opposite of slightly is considerably, greatly, wholly or completely.
What is the opposite of the adverb badly?
The adverb "well" is the usual opposite of the adverb "badly." If "badly" is used to mean "extremely or greatly" the opposite could be "slightly." E.g. He was badly bruised./He was slightly bruised.
What are ultraviolet waves?
Light waves that are of slightly higher frequency than you can see.
What was the effect on the input impedance of lowering the operating frequency?
The input impedance should increase slightly for the lower frequency, when using a capacitive circuit.
What measurements does a hole have to be in a chicken coop so the chickens can get outside?
Slightly bigger than the chicken.
Why would there be different published values for the normal range of a particular measurement?
Different people or organizations may have made slightly different measurements. Measurements are never 100% accurate.
Why induction motor runs slightly slower than supply frequency?
if the motor is at synchronous frequency there is no current induced in the shorted windings in the rotor so at no load its slightly less. if you drive the motor faster than synchronous speed it becomes a generator

Two sound waves of equal amplitude with slightly different frequencies will result in?
A beat frequency.
What are Selena gomez's measurements?
As of April 2011, Selena Gomez's measurements were 34 inch bust, 24 inch waist, and 36 inch hips. However, measurements change all the time, and are not constant, so they might be slightly different now.
What feature makes a water polar molecule?
the ends of the water molecule have opposite electrical charges
How the frequency changes with change in thickness of a cotton string?
In an experiment I did with silicon carbide fibers, the thicker fibers (bigger diameter) had slightly higher frequencies (referring to the first natural frequency).
