Why might a bright yellow solid form when two clear colorless liquids are mixed? Explanation: When two substances (can be aqueous or liquids) in solution react, they yield a solid and an aqueous compound. This is a double displacement reaction in which the solid is known as a precipitate. Can two solids react to form […]

What is the charge on the 2uf capacitor? Answer. Answer :- No charge flows in 2uf capacitor at steady state. In steady state there is no charge which flows in capacitor. What is charge of 3 uF capacitor in steady state? In the circuit shown, the charge on the 3uF capacitor at steady state will […]

What happens when you shine a red light on a blue object? So what happens if you shine only red light onto a blue object? All of that red light gets absorbed and the blue object will seem to be dark, almost black. If you now shine a blue light onto that blue object all […]

How many miles will be traveled by at least 80 percent of the trucks? 39,900 miles How many miles can a trucker drive in a week? 3,000 miles How long can a truck driver drive before resting? Drivers can drive for up to 11 hours during the duty period. However, after driving for eight hours, […]

What triggers sweating? Sweating is your body’s mechanism to cool itself. Your nervous system automatically triggers your sweat glands when your body temperature rises. Sweating also normally occurs, especially on your palms, when you’re nervous. The most common form of hyperhidrosis is called primary focal (essential) hyperhidrosis. Where do humans sweat the most? The human […]

Why is curiosity rover so slow? Originally Answered: Why does the Mars rover, Curiosity, move so slow? There are delicate instruments and experiments on board, and besides, they’re in no real “rush” to get anywhere, since so much science can be done even at the landing site while they figure out which route to pursue […]

What happens to the pH of a base when water is added? Adding water to an acid or base will change its pH. The acid is becoming less acidic. Similarly, when an alkali is diluted with water the concentration of OH – ions decreases. This causes the pH of the alkali to fall towards 7, […]

When a capacitor is connected to a battery? If an uncharged capacitor C is connected to a battery of potential V, then a transient current flows as the capacitor plates get charged. The flow of current from the battery stops as soon as the charge Q on the positive plate reaches the value Q = […]

How is glucose prevented from leaving the cell? First Half of Glycolysis (Energy-Requiring Steps) This reaction prevents the phosphorylated glucose molecule from continuing to interact with the GLUT proteins, and it can no longer leave the cell because the negatively charged phosphate will not allow it to cross the hydrophobic interior of the plasma membrane. […]

Can there be 2 experimental groups? The experimental group is the set of subjects exposed to a change in the independent variable. It’s possible for an experiment to contain more than one experimental group. However, in the cleanest experiments, only one variable is changed. What do you need to observe to develop a good experimental […]
