What is a variable that does not change in an experiment?
The variable that stays the same throughout the entire experiment is called the control.
What is the difference in a mamo-genius sloution and hetro-genius solution?
I think you mean homo genius and hetero genius solution. Homo genius means that it's all the same throughout and can't be separated without chemical means. Like a cup of tea or salt water. Hetero genius means it can be separated into different parts like sand on the beach. It would separate the bits of non-sand without too much trouble.
What is the purpose to conduct grease cone penetration test?
The cone penetration value gives information on the consistency of the grease. If the cone sinks deeper into the grease, the grease has a lower consistency and will flow more easily. The consistency of greases is divided into different classes by the NLGI. Customers use these classes as an indication of how fluent a grease is at 25 degrees Celsius. The cone penetration test is also used as a way to quickly confirm if the delivered grease is on specifications.
In the early days of grease testing the cone penetration test was thought to say something about the viscosity of the grease. However, since those days it was proven that greases do not have one viscosity but that this viscosity is a very complex variable among others dependent on the greases previous history, on temperature and on time. This is why for theoretical research the cone penetration test does not have a lot of value.
Experiments and investigations must be?
In order for an experiment to be considered ethical, and in some cases legal, it must be approved by a governing body. Often, this body is a research institution like a school, but sometimes the approval has to come from higher up.
Why do some objects float and others sink?
Whether an object floats or sinks is a function of its relative density, to the medium in which it is placed. If the object is less dense, it floats, If it is more dense, it sinks.
Density = Mass per unit Volume
A desert is an area devoid of water. However, there often is a minimal amount of rainfall, and there may be underground aquifers.
What causes hard time removing bowels?
Did you ever stop to think that maybe the reason you're having such a hard time removing your bowels is because God never wanted us to be able to remove them? There's a reason God made us with bowels (not to get all religious on you or anything) -- I'm not sure what it is, but I AM pretty darned sure that there's a reason. I mean, I think there HAS TO be, right? At least I hope there is ...
Besides, you could bleed to death attempting a stunt like this without proper medical education.
What is wet-dog shake behavior?
It's their instinct to dry themselves off. They didn't have towels when evolving...
or it's an epileptic seizure mostly seen in rats that mimics the behavior mentioned above
When will the results be known?
The words result or result indicates some conclusion or conclusions made or revealed about something.
General Life
A result can occur from an action.
Example: I stepped on the gas pedal, resulting in the car moving forward.
Mathematics
A result in Math is a mathematical answer. The result is known after you figure or work the problem.
Science and Experiments
A result is is a conclusion found after running the experiment.
Medical Tests
Medical Tests can have results within minutes, hours, days, or weeks. It depends on the type of test.
Home Pregnancy Tests
Results from a Home Pregnancy Test are known within minutes.
School or University Tests, Placement Tests, Finals
For the results of School or University Tests, Placement Tests, or Finals, each school or university sets their own schedule. Check with your institution for the reporting date.
When a force is applied to a body in what direction will the body accelerate?
Acceleration is in the same direction as the applied force.
What is the force called between the bottom of the boat and water?
the name of the force is upthrst and t is greater than the force that the boat excert to/on /in the water
What is the use of the flask in the laboratory?
Laboratory flask of different types are designed to contain liquids in larger volumes.
Why does steam come out of a fresh bag of popcorn?
Popcorn pops because of the water content in the kernels. Heating the kernels, whether by microwave or by some other means, turns the water into steam, which expands and breaks the kernels. Admittedly, this is a small amount of water, but it doesn't take much steam, to pop a kernel.
