How is a closed system defined? A closed system is a physical system that does not allow transfer of matter in or out of the system, though, in different contexts, such as physics, chemistry or engineering, the transfer of energy is or is not allowed. … What happens when heat is removed from air in […]

How do you describe a position time graph? In a position-time graph, the velocity of the moving object is represented by the slope, or steepness, of the graph line. The position of the object is not changing. The steeper the line is, the greater the slope of the line is and the faster the object’s […]

What color can I mix with purple? So for a triad, you’d get purple, green, and orange. You can also play with purple in its various tints and shades, and mix and match with neutrals like white, black, grey, and brown. What happens if I dye my green hair purple? If you apply fantasy purple […]

What is the rule of balance? Conclusion: On a separate sheet of paper, make a claim in which you mathematically state the rule of balance – that is, the rule that one must use to determine if two weights placed on opposite sides of the fulcrum will balance each other. What is a balanced photo? […]

What is the difference between and asteroid and a meteor? In simplest terms here are the definitions: Asteroid: a large rocky body in space, in orbit around the Sun. Meteoroid: much smaller rocks or particles in orbit around the Sun. Meteor: If a meteoroid enters the Earth’s atmosphere and vaporizes, it becomes a meteor, which […]

What is the purpose of lithosphere? The lithosphere is largely important because it is the area that the biosphere (the living things on earth) inhabit and live upon. If it weren’t for the tectonic plates of the lithosphere there would be no change on Earth. Where is the lithosphere found? The lithosphere is the solid, […]

Does a fired bullet hit the ground at the same time as a dropped one? There you have it. The y-component of air resistance for the fired bullet still depends on the fired speed of the bullet (since it is proportional to v2). A fired bullet (with air resistance) does not hit the ground at […]

What are 3 exercises? The three main types of exercise are cardiovascular exercise, strength training and stretching. All three types of exercise are important for physical fitness. What are 3 types of resistance exercises? Summary Resistance training increases muscle strength by making your muscles work against a weight or force. Different forms of resistance training […]
