What is the important of matter? Matter is important for us because it has mass and it occupies space therefore all things that we can touch and see is part of matter. We students should have our own background in matter because matter have many forms and we should study and know them well so […]
What causes the pail to move in circular motion?
What causes the pail to move in circular motion? As a bucket of water is tied to a string and spun in a circle, the tension force acting upon the bucket provides the centripetal force required for circular motion. As the moon orbits the Earth, the force of gravity acting upon the moon provides the […]
What happens to the current in a circuit if a 1.5 volt battery?
What happens to the current in a circuit if a 1.5 volt battery? What happens to the current in a circuit if a 1.5- volt battery is removed and replaced by a 9-volt battery? The current would increase. 10. The relationship between resistance and current in a circuit is that the greater the resistance the […]
What are the four elements that can have double bonds?
What are the four elements that can have double bonds? Double bonds are common for period 2 elements carbon, nitrogen, and oxygen, and less common with elements of higher periods. Metals, too, can engage in multiple bonding in a metal ligand multiple bond. How do you know if it’s a single double or triple bond? […]
What are the main benefits of switching from incandescent to fluorescent bulbs?
What are the main benefits of switching from incandescent to fluorescent bulbs? Fluorescent lamps also do not produce as much heat as traditional lighting options. They make about 75% less heat compared to an incandescent bulb because they are not using resistance to emit light. That also results in an energy savings, and also helps […]
What is the minimum resultant force?
What are the 3 main nutrient cycles in an ecosystem?
What are the 3 main nutrient cycles in an ecosystem? The three main cycles of an ecosystem are the water cycle, the carbon cycle and the nitrogen cycle. These three cycles working in balance are responsible for carrying away waste materials and replenishing the ecosystem with the nutrients necessary to sustain life. What is a […]
Is Anti-Gravity theoretically possible?
Is Anti-Gravity theoretically possible? In the 20th century, Newton’s model was replaced by general relativity where gravity is not a force but the result of the geometry of spacetime. Under general relativity, anti-gravity is impossible except under contrived circumstances. How did they do zero gravity in away? For the space scenes, they attached each actor […]
What is a group of humans called?
What is a group of humans called? Community,gathering,crowd,mob,guerillas’ or terrorists! There are all sorts of words for groups of humans: nation, corporation, family, club, mob, gang, etc etc. What is a group of snakes called? A group of snakes is generally a pit, nest, or den, but they’re generally thought of as solitary creatures, so […]
What is valve angle?
What is valve angle? Valve angle defined as the angle between a valve axis and a cylinder axis is one of the most important design factors that may have an influence on valve train design, cylinder head size, in-cylinder flow, etc. What is Valve face angle? The face of the valve is usually ground to […]
