What does the period one complete to and fro of a pendulum such as swing depend on quizlet?
Galileo discovered that the time a pendulum takes to swing to and fro through small distances depends on only the length of the pendulum. the time of a to-and-fro swing, called the period, does not depend on either the mass of the pendulum or the size of the arc through which it swings.
Which of the following clocks would keep accurate time if you took them to the moon?
Gravity also affects balance clocks, shifting the equilibrium position of the block part of the clock downward. Of these three clocks, a quartz clock is the only one that is not affected in some way by gravity; therefore, it would keep accurate time if you took it to the moon.
Why is a violin string vibrating up and down in its fundamental vibrational mode an example of a standing wave rather than traveling wave?
Why is a violin string vibrating up and down in its fundamental vibrational mode an example of a standing wave rather than a traveling wave? Crests and troughs don’t travel along the string. The region of maximum motion moves along the string and there is no pattern that simply vibrates back and forth in place.
When an airplane’s two propellers are turning at almost the same rate their combined sound can have a pulsing character to it explain that pulsing?
Interference between the two sound waves causes a beating effect. When an airplane’s two propellers are turning at almost the same rate, their combined sound can have a pulsing character to it. Explain that pulsing. Interference between the sound waves from the two propellers causes a beating effect.

I would try heating it gently in microwave or boiling water to get it back to liquid. Then you can dilute it with sap or syrup and make it into candy or sugar, (crumb).
What happens when you heat maple syrup to cool it?
How does boiling the sap change its consistency? When a sugary solution is heated, some of the water evaporates, and this makes the sugar more concentrated in the solution and the overall product thicker. As the heated maple syrup cools, sugar molecules (the smallest particles of the sugar) can form crystals.
Is it okay to heat maple syrup?

How can you tell if maple syrup has gone bad?
- Maple syrup doesn’t really go bad if you store it properly.
- Another sign that something bad is going on is that your maple syrup smells off.
- The smell can be sour (fermentation), yeasty, or simply “funny.” If the smell is off, just throw it away.
Is mold in maple syrup dangerous?
The good news is that the mold that grows in maple syrup is non-toxic (via Epler’s Maple Syrup). Instead, remove the mold from the surface of the maple syrup, then heat it to boiling. Let the syrup cool, skim off any remaining floaties, and add it to a clean container. Your maple syrup is safe to eat again!
Is it necessary to refrigerate maple syrup after opening?
Storage: Do you need to refrigerate maple syrup once opened? YES. Once the container is open, maple syrup should be refrigerated. Once in contact with air, mold could develop if the product is not refrigerated.
What happens if you don’t refrigerate maple syrup?
Maple syrup does not really need to be refrigerated. However, refrigerating maple syrup will retard the growth of mold. If a container of unrefrigerated maple syrup is not checked often, enough mold may grow in the syrup, to ruin the flavor of the syrup. Maple syrup may also be frozen.
Can I stop boiling sap and start again?
No! The point of boiling sap is to eliminate water, by having a lid on the pot, the water condenses on the lid and drips back into the sap, repeating the process and increasing the amount of time it takes to boil sap into syrup.
Do you need to refrigerate ketchup?

Why does Europe not refrigerate eggs?
Without the cuticle, eggs must be refrigerated to combat bacterial infection from inside. In Europe, it’s illegal to wash eggs and instead, farms vaccinate chickens against salmonella. With the cuticle intact, refrigeration could cause mildew growth and contamination.
Is it safe to eat eggs that float?
