Can something have more than one type of energy? Energy comes in many different types, which can be categorised into two basic forms – kinetic and potential. Energy can never be created or destroyed, but it can be transformed from one type of energy to another. What happens if you drop the skater onto the […]
Can matter be separated?
Can matter be separated? Matter can be broken down into two categories: pure substances and mixtures. Various separation techniques exist in order to separate matter, including include distillation, filtration, evaporation and chromatography. Matter can be in the same phase or in two different phases for this separation to take place. Which substance can not be […]
What is the difference between a constant variable and a control group?
What is the difference between a constant variable and a control group? Just so you remember: variables and constants are part of your experimental group (the group on which you are testing). And the control is a separate group that is not being tested on but is still being observed. What is the difference between […]
Will you vs Can you?
Will you vs Can you? May implies that you are asking for permission. Can implies that you are questioning somebody’s ability. Will implies that you are seeking an answer about the future. Can V could? The modal verbs can and could represent the ability of a person or thing in doing something. However, there is […]
What do you know about a substance it you know its temperature?
What do you know about a substance it you know its temperature? In chemistry, we define the temperature of a substance as the average kinetic energy of all the atoms or molecules of that substance. Not all of the particles of a substance have the same kinetic energy. At any given time, the kinetic energy […]
Does adding more substrate increase rate reaction?
Does adding more substrate increase rate reaction? The rate of formation of product now depends on the activity of the enzyme itself, and adding more substrate will not affect the rate of the reaction to any significant effect. The rate of reaction when the enzyme is saturated with substrate is the maximum rate of reaction, […]
Is it possible for a concave lens to form a real image?
Is it possible for a concave lens to form a real image? Convex (converging) lenses can form either real or virtual images (cases 1 and 2, respectively), whereas concave (diverging) lenses can form only virtual images (always case 3). Real images are always inverted, but they can be either larger or smaller than the object. […]
Why is sodium fluoride used in toothpaste?
Why is sodium fluoride used in toothpaste? USES: Sodium fluoride makes teeth more resistant to decay and bacteria that cause cavities. This medication is used to prevent cavities. Is sodium fluoride positive or negative? It is neutral because the Na and F atoms are transferring their valence electrons in order to become stable. This results […]
Do heavier objects fall faster?
Do heavier objects fall faster? Galileo discovered that objects that are more dense, or have more mass, fall at a faster rate than less dense objects, due to this air resistance. How do you find velocity with time and height? An object is thrown straight up from the top of a building h feet tall […]
Is Earth 666 destroyed?
Is Earth 666 destroyed? Earth-666 was destroyed by antimatter during the Anti-Monitor Crisis. Why is it called Earth 616? The main Marvel universe was labeled as 616. Alan Moore chose this designation as a counter to the single-digit numbers for earths in DC. He wanted to emphasize that the main earth was not special. 616 […]
