What will be the velocity of a ball thrown vertically upwards when it reaches the maximum height? Therefore, at maximum altitude the velocity of the ball must be zero. Question: A ball thrown vertically upward reaches a maximum height of 30 meters above the surface of Earth. At its maximum height, the speed of the […]

A salt is the product of an acid-base reaction and is a much broader term then common table salt as shown in the first reaction. The following are some examples of neutralization reactions to form salts. What is […]
When should I worry about bradycardia?
When should I worry about bradycardia? If you have bradycardia (brad-e-KAHR-dee-uh), your heart beats fewer than 60 times a minute. Bradycardia can be a serious problem if the heart doesn’t pump enough oxygen-rich blood to the body. For some people, however, bradycardia doesn’t cause symptoms or complications. What happens if bradycardia is left untreated? If […]
Why is solar wind bad?
Why is solar wind bad? It moves very fast, then smacks right into Earth’s magnetic field. The blow causes a shock to our magnetic protection, which can result in turbulence.” Knowing more about the effects of the solar wind is not only important to those of us who live on Earth. What is solar wind […]
Which two factors can contribute to enzyme catalysis?
Which two factors can contribute to enzyme catalysis? Several factors affect the rate at which enzymatic reactions proceed – temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators. What is enzyme catalysis examples? Enzymes are biological catalysts. Enzymes are also proteins that are folded into complex shapes that allow smaller […]

What is resultant force give example?
What is resultant force give example? Translation: When a system of forces is acting on an object, the difference between the forces is called the Resultant force. For example, a 3N force to the left and 10N force to the right gives a resultant force of 7N to the right. What is resultant moment? Moment […]
How long does it take for a drop of blood to dry?
How long does it take for a drop of blood to dry? 60 minutes Does blood turn brown on paper? Does blood turn brown when it dries on paper due to rusting of the iron? Iron rusts because oxygen oxidizes iron. Hemoglobin contains iron in the +2 oxidation state. When hemoglobin combines with oxygen for […]
What is the chemical reaction of photosynthesis?
What is the chemical reaction of photosynthesis? The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, […]
Which of these rocks is formed by erosion and deposition?
Which of these rocks is formed by erosion and deposition? Sedimentary rock What makes sedimentary rocks unique? Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth’s surface. Sedimentary rocks often have distinctive layering or bedding. What is the best known feature of sedimentary […]
