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 […]
Which transmission characteristic is never fully achieve?
Which transmission characteristic is never fully achieve? bandwidth Which fiber transceiver is the same size as SFP? Which fiber transceiver is the same size as SFP transceivers, but can support network speeds over 10 Gbps? The SFP+ is the same module size as SFP; theoretical maximum transmission speed is 16 Gbps. Suppose you’re assisting with […]
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 […]
Should peanut butter be refrigerated?
Should peanut butter be refrigerated? An open jar of peanut butter stays fresh up to three months in the pantry. After that, it’s recommended to store the peanut butter in the fridge (where it can maintain its quality for another 3-4 months). If you don’t refrigerate, oil separation can occur. Here’s a run-down. How long […]
How much is your true weight if the scale shows 100 kg?
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 […]
