What are variables?

Variables are defined as any characteristics, number or quantity which can be measured . It can also be called as a data item . It is called as variable because they can vary and can have variety of values.

There are three types of variables 1) manipulated variable where in a condition is specified, 2) responding variable which is dependent on manipulated variable 3)controlled variable  which do not change

Example of manipulated variables are number of hours spent by a student studying , that of responding variable is result of a student and temperature is an example of controlled variable.

Sublimation is the process by which solids are instantly transformed into gases. The forces of attraction between solids are completely defeated when they absorb enough energy. Solids, such as dry ice, undergo sublimation.

What is sublimation?Similar to melting, freezing, and evaporation, sublimation is a form of phase transition, or change in a state of matter. Without ever entering a liquid phase, a substance transforms from a solid to a gas through sublimation. Typical sublimation examples include dry ice, which is solid CO2,additional elements that cannot be sublimated. A solid-solid combination is separated by sublimation when one of the components sublimes (transforms from solid to gaseous state without producing liquid) following heating, leaving the other non- sublimable components behind.Sublimation is the direct transition of a substance from the solid phase to the gas phase without passing through the liquid phase in between. Sublimation is an endothermic phase transition that occurs at temperatures and pressures lower than a chemical's triple point in the phase diagram.

The softball’s velocity goes to 0 meters/second in 0.8 seconds when caught. If the softball has a mass of 0.2 kilograms, what’s the force of the impact? Use F = ma, where .

Answers

Answer:

To calculate the force of impact F, first lets calculate the acceleration a of the ball:

a=v/t where v is the velocity of the ball and t is time

a=32/0.8=40 m/s²

To get the force F we need the Newtons second law:

F=m*a where m is the mass of the ball and a is the acceleration.

F=m*a= 0.2*40 = 8 N

So the impact force is F= 8 N.

I WILL GIVE BRAINLIEST

Answers

Answer:

Cleaning up oil spills and metal contaminates in a low-impact, sustainable and inexpensive manner remains a challenge for companies and governments globally.

But a group of researchers at UW–Madison is examining alternative materials that can be modified to absorb oil and chemicals. If further developed, the technology may offer a cheaper and “greener” method to absorb oil and heavy metals from water and other surfaces.

Aerogels, which are highly porous materials and the lightest solids in existence, are already used in a variety of applications, ranging from insulation and aerospace materials to thickening agents in paints. The aerogel prepared in Gong’s lab is made of cellulose nanofibrils (sustainable wood-based materials) and an environmentally friendly polymer. Furthermore, these cellulose-based aerogels are made using an environmentally friendly freeze-drying process without the use of organic solvents.

It’s the combination of this “greener"material and its high performance that got Gong’s attention.

“For this material, one unique property is that it has superior absorbing ability for organic solvents — up to nearly 100 times its own weight,” she says. “It also has strong absorbing ability for metal ions.”

Treating the cellulose-based aerogel with specific types of silane after it is made through the freeze-drying process is a key step that gives the aerogel its water-repelling and oil-absorbing properties.
