When a small stone is dropped into a pond of still water what happens? When that pebble is dropped in the pond, it pushes water out of the way. The water has nowhere to go but to the side and up, creating a circular peak around the drop point. This peak falls again, under the […]
How gravity affects the movement of object?
How gravity affects the movement of object? On Earth, gravity pulls all objects to Earth’s center. Gravity acts on all masses equally, even though the effects on both masses may be different because gravity causes all objects to fall at the same constant rate of 9.8 m/s2. An object in free fall means that the […]
What are the similarities and differences between kinetic and potential energy?
What are the similarities and differences between kinetic and potential energy? KE is the energy possessed by an object by virtue of it being in motion. PE is the energy possessed by an object by virtue of its position. It can be transferred from one object to another and this happens during collisions. Potential Energy, […]
What is sliding friction with example?
What is sliding friction with example? Specific examples of sliding friction include: Rubbing both hands together to create heat. A sled sliding across snow or ice. Skis sliding against snow. A person sliding down a slide is an example of sliding friction. What is the formula for sliding friction? The coefficient of friction (fr) is […]
Why is it important to use scientific method?
Why is it important to use scientific method? The scientific method attempts to minimize the influence of bias or prejudice in the experimenter. Even the best-intentioned scientists can’t escape bias. That’s the job of the scientific method. It provides an objective, standardized approach to conducting experiments and, in doing so, improves their results. Why is […]
Which is hotter magma or lava?
Which is hotter magma or lava? When geologists refer to magma, they’re talking about molten rock that’s still trapped underground. If this molten rock makes it to the surface and keeps flowing like a liquid, it’s called lava. They’re also the hottest variety of magma, reaching temperatures between 1,800 degrees to 2,200 degrees Fahrenheit. Whats […]
What is Zn plus S?
What is Zn plus S? Names: Zinc sulfide , Zincblende , Wurtzite show more. Appearance: White-to-yellow crystals or powder. Is Zn a reactant? A reactant is a substance that is present at the start of a chemical reaction. The substance(s) to the right of the arrow are called products. In the equation above, the zinc […]
What is the actual weight of molecule of water?
What is the actual weight of molecule of water? Therefore, 18g of mass of water is occupied by 6.022×1023 number of molecules. Therefore, we can calculate the mass of one molecule of water by dividing the mass of one mole of water and Avogadro number. The actual weight of a molecule of water is calculated […]
