Yes. It's an effect called 'resonance' - two identical things can vibrate in synch if the vibrations of one can someone pass to the other. The usually way of doing this is to stand them both on the same surface, so that the vibration can pass through that object.
Because they're designed that way. A tuning fork can be, well, "tuned" to have any desired frequency. If these are for tuning musical instruments, they sound like very old tuning forks. The "middle C = 256 Hz" scale was in limited use at one time, but by modern standards (where the A above middle C is tuned to 440 Hz, or in some cases even higher) is a bit on the low side. Tuning your instrument to C=256Hz will make it sound "flat".
It is a tuning fork whose vibrations are sustained (by hammering it continuously in a way similar to the break and make arrangement of electric bell) with the help of an electromagnet.
No frequency is completely safe.
The best way to get those E notes is to use a piano. Another way, just as good, is to use another tuned guitar.
If there is resonance, then making one vibrate will also make the other one vibrate in a noticeable way, since:* The vibrations are transmitted through the air, and * Any such small effect is reinforced, over time, due to resonance.
There was debate as to which way to get to Missouri. At a fork in the river Clarks camp went south, the left fork.

A protractor is the most accurate way of measuring angles.

A frequency table is a way of tabulating data, where the independent variable (that is, what you are measuring, such as height or length) is listed in the left hand column. The frequency, which is the number of times the independent variable occurs, goes on the right hand column. Sometimes, we represent the frequency by means of tally marks. A grouped frequency table groups the independent variable into "classes": e.g. 0 - 5, 6 - 10, 11 - 15...
The strength of an item is just as much about its design as it is about the material, so there's no way to tell. A poorly built alloy fork, will be weaker than a well built carbon fork as well as the other way around.
Relative frequency is a method of calculating the frequency of an event. Percentage frequency is a way of presenting the frequency of an event.
With a fork.
According to Tiffany's Table Manners for Teenagers (1989):image showing a fish fork held as a normal fork is held and with the text - "This is the way to hold the fork. Prongs should always be down when the fork is held in the left hand".image showing a fish knife held as a writing penand with the text - "This is the way to hold the knife. Note that it differs from the way the meat knife is held."
The best way to use a roast fork for cooking a delicious meal is to pierce the meat with the fork to hold it in place while cooking. This helps the meat cook evenly and allows for easy flipping. Be sure to use the fork with caution to avoid any accidents.
You can use plastic or metal measuring utensils for measuring flavoring.
