A photogate and timer are considered accurate and precise because they use light beams to detect motion and measure time intervals with high resolution. The digital nature of the timer minimizes human error and provides consistent measurements, while the rapid response of the photogate allows for quick detection of objects passing through. This combination results in reliable data that can be replicated in multiple trials, enhancing both accuracy and precision in experiments.
What else can I help you with?
What can you use instead of a stopwatch to be more accurate?
Instead of a stopwatch, you can use a digital timer or a smartphone app specifically designed for precise timing, as these often feature advanced functions like lap timing and split times. For even greater accuracy, consider using a GPS-based timing device or a high-speed camera that can capture time intervals with frame-by-frame analysis. Additionally, specialized timing systems used in professional sports can provide highly accurate measurements.
How do you get 16 minutes by using a 10 and7 minute timer?
You set the 10 minute timer for 9 minutes and the 7 minute timer for the full 7 minutes.
Why is zero not considered a counting number In timer down counters it counts down to zero?
If a timer is counting down from 30, it doesn't actually count 30. It starts counting at 29. If you are counting up to 10, you wouldn't count the number that you are counting from. If you counted 0, you would actually be counting 11 numbers.
You have 2 sand filled egg timers one for 9 minutes and one for 2 minutes. how can you use both of them to time a 5 minute egg?
you put the 9minute timer and the 2minute timer on together when the 2min timer finishes flip it 2min timer to make 4mins. when the 2min timer is finished start timing the egg and wait for the 9min one to finish :)
How many times must a three-minute timer be flipped to measure a half hour?
1 hour = 60 minutes. Half an hour = 60/2 = 30 minutes. 30 minutes = 30/3 = 10 turns on a 3-minute timer PROVIDED the timer is turned at exactly the right moment and turning the timer takes no time at all.
How accurate is mechanical stopwatch?
Mechanical stopwatches are generally accurate to within a fraction of a second, depending on the quality and maintenance of the stopwatch. However, they are not as precise as digital stopwatches due to the potential for human error in starting and stopping the timer manually.
How much of a difference is there in accuracy using a CDN digital timer over a regular kitchen timer?
A CDN will be more accurate, but a regular kitchen timer, if used properly, is very accurate as well.
Can you work 1hour and be considered a full timer?
No
How do you disable Mr coffee timer?
To disable the timer on a Mr. Coffee coffee maker, locate the timer button or control panel. Depending on the model, you may need to press and hold the "Program" or "Auto" button until the timer display turns off or resets. If your model has a specific button for the timer, simply press it to deactivate the programmed timer. Always refer to your specific model's manual for precise instructions.
Can 555 timer be considered a digital device?
You can use it in both analog and digital circuits but it is considered as a digital device.
How much does it cost to run a wall timer?
The cost to run a wall timer depends on various factors such as the type of timer, the energy consumption of the device being controlled, and the local electricity rates. On average, a wall timer may cost around a few cents per day to operate. It is best to check the user manual of the specific wall timer for more accurate information.
Why would a hand held stopwatch NOT accurate times for a race?
A handheld stopwatch may not provide accurate timing for a race due to human error in starting and stopping the timer, leading to delays or premature stops. Additionally, the reaction time of the person operating the stopwatch can introduce inconsistencies, especially in races with precise time requirements. Environmental factors, such as distractions or the operator's focus, can also affect timing accuracy. Lastly, the stopwatch may have limitations in resolution, preventing it from capturing very precise times needed for competitive events.
Why 555 timer is used in fire detection?
A 555 timer is used in fire detection because it can take samples at regular intervals. This allows the mechanisms to accurate detect fires without a need to constantly strain the batteries.
What is the 555 IC timer measured in?
there are 3 resistors of 5k each...hence the name 555
If i had a three minute eggtimer and a five minute eggtimer and i need to boil an egg for seven minutes how would you do this?
I would use my watch, or the timer function of my microwave. Or you can start both timers at the same moment, before putting the egg in the water. When the 3-minute timer ends, put the egg in. This leaves 2 minutes on the 5-minute timer, assuming both timers are relatively accurate. When the 5-minute timer ends, re-set it again for 5 minutes, and you will have your 7 minute egg when the timer ends.
What are the four timers used in TCP?
Connection establishment timer, persist timer, keepalive timer, retransmission timer
What are the best features to look for in a salmon rice cooker to ensure perfectly cooked salmon every time?
The best features to look for in a salmon rice cooker for perfect results include a precise temperature control, a steam tray for even cooking, a timer function for accurate cooking times, and a non-stick inner pot for easy cleaning.
