What makes the ball keeps on rolling? When a rigid ball rolls on a plane with no other forces, it is known that no friction applies and the ball keeps rolling. Static friction applies in the opposite direction of the tangential part of the external force, with equal magnitude. What do you call the force […]
How does a ionic bond form?
How does a ionic bond form? An ionic bond is formed by the complete transfer of some electrons from one atom to another. The atom losing one or more electrons becomes a cation—a positively charged ion. The atom gaining one or more electron becomes an anion—a negatively charged ion. What must occur for an ionic […]
What are the 3 electron carriers?
What are the 3 electron carriers? Oxidation-reduction reactions always happen in matched pairs; no molecule can be oxidized unless another is reduced. Flavin Adenine Dinucleotide. Flavin adenine dinucleotide, or FAD, consists of riboflavin attached to an adenosine diphosphate molecule. Nicotinamide Adenine Dinucleotide. Coenzyme Q. Cytochrome C. Is NADH an electron carrier? NADH is the reduced […]
Can you bounce a basketball on grass?
Can you bounce a basketball on grass? At least two different surfaces to bounce a basketball on, with at least one hard surface and one soft surface (For example, you could use carpet, concrete, grass, linoleum and a basketball court. The surface needs to be flat and next to a wall or other large perpendicular […]
What causes a solution to be conductive?
What causes a solution to be conductive? When a solution conducts electricity, the charge is carried by ions moving through the solution. Ions are atoms or small groups of atoms that have an electrical charge. Some ions have a negative charge and some have a positive charge. Pure water contains very few ions, so it […]
What are the limitations of classical mechanics?
What are the limitations of classical mechanics? One experimental phenomenon that could not be adequately explained by classical physics was black-body radiation. Hot objects emit electromagnetic radiation. The burners on most electric stoves glow red at their highest setting. What are the inadequacy of classical mechanics? The inadequacy of Classical Mechanics are : It does […]
What is the melting point of acetic acid?
Why is NASA important to our daily life?
Why is NASA important to our daily life? Space technology has helped astronauts and scientists to research stars, planets, and the creation of the universe. The technologies discovered by NASA to explore new horizons for humanity are now being put to everyday applications. How does NASA affect the environment? From solar arrays and fuel cells […]
What is mean by nuclei?
What is mean by nuclei? Plural nuclei (nōō′klē-ī′) The positively charged central region of an atom, composed of one or more protons and (for all atoms except hydrogen) one or more neutrons, containing most of the mass of the atom. The number of protons in the nucleus determines the atom’s atomic number and its position […]
Why different objects kept on a table at room temperature do not exchange heat with table?
Why different objects kept on a table at room temperature do not exchange heat with table? Answer. Answer: The sense of touch allows us to recognise temperature differences of objects in the same room which we could easily assume should all be at that same room temperature. The temperature of an object is dependant on […]
