What frequency using shops x cars alarms?
what working frequency are using shops alarms? /or car remote keys frequency ? who knows.... thanks.
How do you find the percentage value in a frequency table?
To find the percentage value in a Frequency table you have to divide each frequency value by the total amount of the sample. For example, if you have 40 cars in a race, and you want to know what is the percentage of the cars that is going 65 mph you then check to see out of 40 cars how many cars are going 65 mph if I look and there is 5. Five would be my frequency for all the cars going 65 mph, so I Would divide 5 by 40 and then I would get a percentage of 12.5.
Can you race two RC cars at the same time without interference?
If two RC cars are receiving signals on the same frequency, then you can't race against each other. However, many RC cars are designed with multiple frequency capability so that the frequencies can be changed to eliminate any interference.
How we find the relative velocity of two cars moving side b side?
get a speedometer
What are high frequency spark generators?
High frequency spark generators are essential mechanical devices that are used in cars to start the ignition. This device is usually powered by batteries.
Does sound move faster if the temperature increases?
No. Higher frequency waves simply have a shorter wavelength (that is, the distance from one crest to the next). Lower frequency waves have a longer wavelength. The waves themselves propagate at the same speed (roughly) depending on the medium. For example, sound travels faster in metal or water than it does in air. A good illustration of this would be a line of cars. If each wave crest is a car, a high frequency wave would be one where the cars are each 20 feet apart. A low frequency wave would be one where the cars are 200 feet apart. Both "waves" can be travelling at the same speed (say, 30 miles per hour) HOWEVER! IF the listener is traveling faster RELATIVE to the source of the sound, then the frequency will appear higher. This is called the Doppler Effect. Simply put, if I were stationary next to that line of cars in the previous example, they would pass by at some rate per minute. If I were travelling at 30 mph in the opposite direction along side the line of cars, they would pass by be at TWICE that rate per minute, thus their FREQUENCY would appear to be much higher. But again, the cars (that is the sound waves) individually have not changed speed.
How does the wavelength of light compare to frequency of light?
Ultraviolet light occurs just above the range of electromagnetc radiation that is detectable by the human eye and has a shorter wavelength than violet. This means it has a higher frequency since all light waves are presumed to travell at the same speed, whether visible to us or not. To explain this in simple terms, if two trains are travelling at the same speed, and one has short cars and the other has long cars, the one with the short cars will pass by us more cars per minute than the one with the long cars. This is called frequency...the number of times something happens in a given time frame.
Is clutch pedals only found in cars with manual and automatic transmissions?
Clutch pedals are only found in cars with manual transmissions.
