When a capacitor is connected to a battery? If an uncharged capacitor C is connected to a battery of potential V, then a transient current flows as the capacitor plates get charged. The flow of current from the battery stops as soon as the charge Q on the positive plate reaches the value Q = […]

How is glucose prevented from leaving the cell? First Half of Glycolysis (Energy-Requiring Steps) This reaction prevents the phosphorylated glucose molecule from continuing to interact with the GLUT proteins, and it can no longer leave the cell because the negatively charged phosphate will not allow it to cross the hydrophobic interior of the plasma membrane. […]

How can we overcome modal dispersion? One way to reduce modal dispersion is to use graded-index fiber. Unlike the two distinct materials in a step-index fiber, the graded-index fiber’s cladding is doped so that the refractive index gradually decreases over many layers. Which type of fiber has highest modal dispersion? Multimode fiber What is difference […]

How do you use the word use and used? Used to refers to something familiar or routine, as in “I’m used to getting up early for work,” or to say that something repeatedly happened in the past like “we used to go out more.” Use to typically occurs with did; “did you use to work […]

What is the property of minerals that reflects light? Luster What are the two major properties of minerals? A mineral species is defined by two distinct properties: (1) its chemical com- position and (2) its crystal structure. Each mineral has a distinct three- dimensional array of its constituent atoms. This regular geometry affects its physical […]

What two factors can make an object stable? The stability of an object is dependent on two factors: The base width of the object. The center of gravity. What are structures for Grade 3? A structure is a solid that has a shape, size, and purpose. It holds a load. Example: A tennis shoe is […]

What is the direction of net force in circular motion? The final motion characteristic for an object undergoing uniform circular motion is the net force. The net force acting upon such an object is directed towards the center of the circle. The net force is said to be an inward or centripetal force. What is […]

What is the Sun an example? The sun is the star that is the central object in the solar system. It is made up of 92% hydrogen, almost 8% helium and the rest is assorted elements. An example of sun is what rises in the east and sets in the west each day. The radiant […]

How do rockets rotate? In flight, any rocket will rotate about its center of gravity, a point which is the average location of the mass of the rocket. Most rockets are symmetric about a line from the tip of the nose to the center of the nozzle exit. We will call this line the roll […]
