Do amps matter on a battery? If the power supply can supply more than 2.1Amps this doesn’t matter as the product will only take 2.1Amps. If the power supply can only supply 1 Amp in this case then either the product will fail to work/charge or charge slowly as it can’t get enough current (or […]

What is an example of the Stroop effect? The Stroop effect is a phenomenon that occurs when you must say the color of a word but not the name of the word. For example, blue might be printed in red and you must say the color rather than the word. What causes the Stroop effect? […]

How many half-lives until a drug is out of your system? Even further, 94 to 97% of a drug will have been eliminated after 4 to 5 half-lives. Thus, it follows that after 4 to 5 half-lives, the plasma concentrations of a given drug will be below a clinically relevant concentration and thus will be […]

Which continent is located at 40 North and 20 East? The 40th parallel north is a circle of latitude that is 40 degrees north of the Earth’s equatorial plane. It crosses Europe, the Mediterranean Sea, Asia, the Pacific Ocean, North America, and the Atlantic Ocean. What city is 41 degrees north and 74 degrees west? […]

What is a diatomic molecule example? Diatomic molecules are composed of only two atoms, of either the same or different chemical elements. Common diatomic molecules include hydrogen (H2), nitrogen (N2), oxygen (O2), and carbon monoxide (CO). The bond in a homonuclear diatomic molecule is non-polar due to the electronegativity difference of zero. Why are some […]

What is the largest part of an atom? nucleus What element has 9 protons and 10 neutrons? fluorine atoms What element has 18 protons and 22 neutrons? Name Argon What element has 9 protons and 9 Neutrons? Name Fluorine What is the number at the end of an isotope’s name? Answer Expert Verified The number […]

How does precipitation affect the weather? Global Climate Change. comes from precipitation. Too little precipitation can result in dry soil, shallow streams, and shortages of municipal water supplies. For example, too much rain or snowmelt (water from melted snow) at one time can lead to flooding. How is rainfall helpful? Rain and snow are key […]

What does d2y dx2 mean? second derivative How can you tell dy dx? Derivatives as dy/dx Add Δx. When x increases by Δx, then y increases by Δy : y + Δy = f(x + Δx) Subtract the Two Formulas. From: y + Δy = f(x + Δx) Subtract: y = f(x) To Get: y […]

Is calcium fluoride acidic or basic? CaF2 is slightly basic. The reason is HF is a weak acid ( but it is very corrosive). When dissolved in water, the F- ion formed will undergoes hydrolysis reaction with water molecules forming HF and OH-. Thats why, it is basic. Does calcium fluoride dissolved in water? Calcium […]

How does pH affect free energy of ATP hydrolysis? Due to the acid-base properties of ATP, ADP, and inorganic phosphate, the hydrolysis of ATP has the effect of lowering the pH of the reaction medium. How does the hydrolysis of ATP perform work? The energy released from ATP hydrolysis into ADP + Pi performs cellular […]
