Hz is short for Hertz, which is the international standard (SI) unit of frequency of an alternating current (AC) voltage. 50Hz means the voltage alternates 50 times per second, 60Hz obviously means 60 times/sec. 60Hz is the normal frequency of the incoming power lines in North America, while 50Hz is seen in many European countries. While convertors exist to use electric devices on a different voltage, convertors generally are not available to use 50Hz devices on a 60Hz power grid, or vice-versa. While some devices can be used on either, many others will not work or may even be damaged. Check with the manufacturer to be sure. Incidentally, since the unit of Hertz is named after the German physicist Heinrich Hertz, it is customary to capitalize the H. So 60Hz is considered correct, while 60hz is not.

How many eggs can snakes have at one time?
It depends on the species - anywhere from 10 to 60 !
How many degrees does the Earth does the earth rotate in one minute?
Let's do some math: The Earth rotates in 24 hours and during that time it covers 360 degrees. One hour has 60 minutes, so a day has 24x60=1440 minutes. Therefore, the Earth covers 360/1440 degrees per day and 0.25 degrees per minute.
How many seconds are there in one degree of longitude?
There are 60 minutes in a degree and 60 seconds in a minute, so a degree has 3600 seconds. These are arc minutes and seconds, no relation to time measurements. A circle has 360 degrees.
What is the difference between physical distance and time distance?
The difference is magnitude, how long the distance is. Physical distance is measured in units like miles and kilometers, and are used for short distances. Time distance is measured in the distance light travels in a unit of time. The units are usually the kilometers light could travel in one year, and they are used for very long distances. Light travels 299,792.458 kilometers in one second. Then it must travel 60 times as far in one minute, 60 X 60 times as far in one hour, 60 X 60 X 24 in one day, and 60 X 60 X 24 X 365 in one year. In other words light travels 60 X 60 X 24 X 365 X 299,792.458 kilometers in one year. That is 9,454,354,955,000,000 kilometers. That number is so huge that it is much easier to say one light year. Alpha Centauri the nearest star to our solar system is approximately 4.22 light years away. Our galaxy the Milky Way is approximately 100,000 light years long. Using a distance measurement would be terribly cumbersome for interstellar distances or the distance between galaxies (intergalactic distances) which are even larger, so we use time distances.
How many planets were in Ptolemy time?
60
How many cycles in 60 Hz?
A cycle is one complete revolution of the sine wave. Hertz is the frequency of the alternating current, how many complete cycles per second. 60 Hertz would have 60 cycles each second.
How does time relate to degrees in an AC sine wave?
One cycle of the sine wave is equal to 360 degrees. In US the frequency of power is typically 60 Hz and hence one cycle is 1/60 of a second. Therefore you can calculate the degrees at any instant of time. If at zero degrees the voltage amplitude is zero, then at 90 degrees,which is 1/4 cycle, wave is at peak voltage. At 180 degrees it is at 1/2 cycle and zero voltage and then at 270 degrees it is 3/4 of the cycle and a peak negative voltage. Finally at 360 degrees the cycle is complete and the voltage is again zero.
How many seconds are there in one cycle as it pertains to 60 cycles?
There is one second in 60 cycles. So 5 cycles is equal to about 0.012 seconds or 12 milliseconds.AnswerThe periodic time is the reciprocal of frequency. So the answer to your question is 1/60 s or 16.67 ms.
What is the phase of a sine wave which is offset one sixth of a cycle with respect to time zero?
1/6th of a cycle is 60 degrees or (pi/3) radians.
The period of an ac wave is?
period is the time duration of one cycle of the waveform, and is measured in seconds/cycle. AC power at 50 Hz will have a period of 1/50 = 0.02 seconds/cycle. A 60 Hz power system has a period of 1/60 = 0.016667 seconds/cycle
What is one second?
A unit of "time" invented by humans which is a measure equal to 1/60 of one "minute", which is equal to 1/60 of one "hour", which is equal to 1/24 of one complete "day". The list goes on..
What is the average percentage of marathon runners complete a marathon?
60 percent of the time they complete it everytime
The required output of an assembly line is 3000 units in an 8 hour shirf the required cycle time for the line is?
It must cycle 3000 times in 8 hours. 8/3000 hr/cycle * 60 minutes/hr * 60 seconds/minute = 28800/3000 seconds/cycle = 9.6 seconds/cycle
What is the length of the cardiac cycle if the heart rate is 80 beats per minute?
To find your answer, your first step is to divide the time (in this case a minute...a minute equals sixty (60) seconds) by the heart rate (e.g. 80 beats). So---60 divided by 80 will give you 0.75 seconds. Your answer will justify the time/length of the cardiac cycle.
How much electricity is 60hz?
Electricity, or AC (alternating current) runs in cycles. It has a positive and negative cycle. One cycle is also referred to as one hertz. In electronics a cycle is also known as a hertz. So when referring to 60 hertz, look at it as seeing one cycle 60 times in a second.
A phase that takes about 50-60 percent of the total time to complete mitosis?

If there is a 60 day money back on the insanity workout and it is only a 60 day workout couldnt you just complete it and then return it?
If there is a 60 day money back on the Insanity Workout and it is only a 60 day workout you could complete it and return it within that time period.
