Why is water a powerful solvent? Water is called the “universal solvent” because it is capable of dissolving more substances than any other liquid. Water molecules have a polar arrangement of oxygen and hydrogen atoms—one side (hydrogen) has a positive electrical charge and the other side (oxygen) had a negative charge. How do you know […]
What are the 4 stages of voice production?
What are the 4 stages of voice production? It involves four processes: Initiation, phonation, oro-nasal process and articulation. Why does my voice sound like it’s vibrating? When you speak, air from your lungs is pushed between two elastic structures—called vocal folds—causing them to vibrate and produce your voice. In spasmodic dysphonia, the muscles inside the […]

Is 230V RMS or peak?
In which of the following cases is the electric field zero but potential is not zero?
In which of the following cases is the electric field zero but potential is not zero? 1. Electric field(E)=0 but Potential(V) is not 0: The electric field is zero at a point exactly midway between two equal and similar charges but the electric potential at that point is twice than that due to a single […]
How do you know seafloor spreading?
How do you know seafloor spreading? Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle’s convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor. What is the oldest seafloor? […]
Which statement describes what happens to an object when it becomes polarized?
Which statement describes what happens to an object when it becomes polarized? When an object becomes polarized, its center of positive charge becomes separated from its center of negative charge. Overall, there are just as many positive charges as negative charges; the object has a balance of charges and is therefore neutral. Which one of […]
How many hours does rice take to digest?
How many hours does rice take to digest? Brown rice, millet, buckwheat, oats and cornmeal take 90 minutes whereas lentils, chickpeas, peas, kidney beans and soy beans takes 2-3 hours to digest. Is rice hard to digest? Rice is a good source of energy and protein, but not all grains are easy to digest. High […]
Can an object move without force?
Can an object move without force? Acceleration is the change of velocity per unit time, so if there is no force, all we know is that the acceleration is zero. Therefore, the velocity is not changing. If the object was already moving, then it will just keep moving. So, yes, the object can be moving […]
