Why do water drops combine on a surface?
Water drops combine on a surface due to surface tension. Surface tension is the property of a liquid that allows it to resist external forces. When two or more water drops come into contact, the surface tension between them causes them to merge into a larger drop.
What happens to a particle in a solid when cooled?
When a solid is cooled, the particles within it lose kinetic energy and move more slowly. This causes them to vibrate less and come closer together, leading to a decrease in the overall volume of the solid. As the temperature decreases further, the particles may align into a more orderly arrangement, resulting in the formation of a solid crystal structure.
What is 12 feet and was buried in the ground along time ago?
two junior t-rexs trying to reach their dinner.
"STS token meters" using "sneakernet" via cards or 20 digit numeric tokens typically can't communicate back to the utility, so they still have to read them and check then for tampering.
It's less than the normal monthly readings, so the utility can save some money.
Really good prepaid smart electric meters like the Echelon (http://www.echelon.com), Elster (http://www.elster.com) or Itron (http://www.itron.com) ones communicate back to the utility company so they get usage information, and are very tamper resistant. Good prepaid electricity payment systems like UtiliFlex (http://www.utiliflex.com) gateway that information into utility company CIS systems, keeping them from having to read a meter, unless they suspect tampering from abbarent usage patterns or tamper alerts.
Does repeatedly pushing an elevator button make the elevator come sooner?
No. Pressing the button once will tell the control logic that a rider is waiting for the lift. It will respond by stopping the next upgoing or downgoing car on that floor. It's that simple.
A substance with a very low Ksp is?
A substance with a very low Ksp has low solubility in water, meaning only a small amount of it can dissolve in solution. Substances with low Ksp values tend to precipitate readily when the solution is saturated.
The process of marking tracks and sectors to prepare the disk to receive data is called what?
The process of marking tracks and sectors to prepare the disk to receive data is called formatting. This process creates the necessary structures on the disk for storing and organizing data in a way that can be easily accessed and managed by the operating system.
What is used to remove calcium carbonate deposits in toilets?
A common method to remove calcium carbonate deposits in toilets is to use a mixture of vinegar and baking soda. Pour vinegar into the toilet bowl, add baking soda, and let it sit for a few hours before scrubbing and flushing. You can also use a commercial descaling product specifically designed for toilets.
What are ring stands used for?
It clamps to a long neck beaker so that you can use a bunsen burner to heat whatever chemical(s) that are present in your concoction.
You should turn the coarse adjustment knob counterclockwise to move the objective away from your slide. This will increase the distance between the objective lens and the slide, allowing you to focus on the specimen more easily.
What does einsteinium look like?
Those who have seen this element, Einsteinium, claim it is a silvery, heavy, radioactive metal.
It is produced after several years of irradiation of plutonium, and then further enhanced. It has no known uses, so information may continue to be sparse.
How far a microphone can detect a sound?
The distance a microphone can detect a sound depends on its sensitivity and directionality. In general, most microphones can pick up sounds within a range of a few feet to several hundred feet, depending on the environmental conditions and background noise. External factors such as wind, obstacles, and interference can also affect a microphone's ability to detect sound.
The graph of velocity vs. time for an object falling from rest with air resistance would show the initial steep increase in velocity as the object accelerates due to gravity. As air resistance increases with speed, the velocity will eventually reach a terminal velocity where the force of gravity is balanced by the force of air resistance, resulting in a constant velocity. This would be represented by a curve that levels off as it approaches the terminal velocity.
How do you get bubble gum out of clothing?
Place the clothing in the freezer to harden the gum, then carefully scrape it off with a butter knife or spoon. If any residue remains, dab it with a cloth soaked in white vinegar or apply a stain remover before washing the clothing as usual.
What kinds of liquids evaporate fast?
Generally, liquids with low boiling points will evaporate faster. This includes substances like alcohol, acetone, and gasoline. Additionally, liquids with high surface areas exposed to air will also evaporate quickly.
Why does a clock go clockwise?
Clocks are made to rotate that way. The clock face is modeled after the sun dial, a more primitive way to track time throughout the day.
Prior to the invention of mechanical clocks, sundials were used to tell time. In the northern hemisphere, the sun's shadow moves around a sundial in a clockwise arc. Mechanical clock dials emulate this motion. Had clocks and sundials been developed first in the southern hemisphere, clocks would go counter-clockwise today. Of course, we would still call that direction clockwise.
If you had to live your life over again what one thing would you change?
For me, personally, I'd change the way I grew up. But everybody, it's different things.
What could women do to make a difference to the work force?
Women can make a difference in the workforce by advocating for equal pay, supporting and uplifting other women, challenging gender stereotypes, pursuing leadership positions, and participating in mentoring programs. By speaking up for their rights, supporting diversity and inclusion, and breaking barriers, women can help create a more inclusive and equal work environment.
What is the convex side of the spoon?
The back. Just remember a cave is a hole as in concave. Convex is the opposite of concave.
How do you pass a urine test for alcohol?
You can pass an alcohol urine test by not drinking or consuming any type of alcohol. Then whenever you go to get an alcohol urine test, there will be no trace of alcohol in your system, there will be no sign of it, and it will allow you to pass your alcohol urine test. In addition, don't come into contact with any form of alcohol (mouthwash, sanitizers, site preparation for injection, inhalation of alcohol vapors, etc. for at least 72 hours before test.
How do you get permanent marker off clothing?
i don't knw if thhis wil work but to get rid of perminate marker on some items you use nail polish remover. It worked for me as i was drawing on a white board (my dad's0 and i noticed it was permanent marker and i got worried but then i found out on the internet that nail remover works
Cotton is primarily composed of cellulose, a complex carbohydrate that makes up the cell walls of cotton fibers. It also contains small amounts of proteins, waxes, pectins, and minerals. The unique structure of cellulose gives cotton its strength, absorbency, and breathability.
All metals can be obtained in a very pure form, sometimes up to a purity of
99,9999 %.
