Does Homework take away free time? Rather than motivating students to master material and learn efficiently, homework negatively impacts students by taking away from personal time that is necessary for them to lead balanced lives. Is HW good or bad? In fact, too much homework can do more harm than good. Researchers have cited drawbacks, […]

What is the best way to describe a metallic bond?
What is the best way to describe a metallic bond? A metallic bond is the sharing of many detached electrons between many positive ions, where the electrons act as a “glue” giving the substance a definite structure. It is unlike covalent or ionic bonding. Metals have low ionization energy. Therefore, the valence electrons can be […]
What does the word intervals mean?
What does the word intervals mean? 1a : a space of time between events or states. b British : intermission. 2a : the difference in pitch between two tones. b : a space between objects, units, points, or states. What is periodic example? The definition of periodic is something that is recurring at regular intervals, […]
Which best describes the relationship between displacement and distance traveled?
Which best describes the relationship between displacement and distance traveled? Displacement is a vector quantity describing the change in position, and distance traveled is the total length travelled c. Displacement is scalar quantity describing the change in position, and distance traveled is the absolute value of displacement d. One ant is observed first at position […]
What plant is sugar made from?
What plant is sugar made from? There are two major sugar crops: sugar beets and sugar cane. However, sugar and syrups are also produced from the sap of certain species of maple trees, from sweet sorghum when cultivated explicitly for making syrup and from sugar palm. Is chocolate a natural resource? Cocoa is considered a […]
What happens to the direction of force if the direction of current changes but the magnetic field stays the same?
What happens to the direction of force if the direction of current changes but the magnetic field stays the same? If the forefinger points in the direction of the magnetic field and the middle finger in the direction of the current, then, the thumb points in the direction of the force exerted on the conductor.So, […]
What does the chemical formula caci2 show about the compound it represents?
What does the chemical formula caci2 show about the compound it represents? Answer: Two elements because Can is one element and Cl is another. The two is a coeficient that states how many of that element there is. I hope this helps you!!! What does the four mean in the formula 4na2so3? The ‘4’ in […]
Why do grain boundaries act as barriers to dislocation motion?
Why do grain boundaries act as barriers to dislocation motion? Since the lattice structure of adjacent grains differs in orientation, it requires more energy for a dislocation to change directions and move into the adjacent grain. The grain boundary is also much more disordered than inside the grain, which also prevents the dislocations from moving […]
Is the law of reflection applicable to all mirrors?
Is the law of reflection applicable to all mirrors? It is a fact that laws of reflection are applicable to all reflecting surfaces. Is law of reflection valid for all kind of mirror? The laws of reflection hold good for all the mirrors irrespective of their shape (i.e. flat or curved). The angle of incidence=angle […]
