What will happen if a spaceship that is motionless in deep space is given a quick push? What will happen if a spacecraft that seems to be motionless in deep space is given some type of quick push? The spacecraft will move and will not stop until it is stopped by an equal and opposite […]
What are the two characteristics of an atom?
What are the two characteristics of an atom? Atoms are the smallest fraction of an element that can exist, and still show the characteristics of the element. Atoms themselves are composed essentially of electrons (1 negative charge), protons (1 positive charge), and neutrons (no charge). Why does each atom have specific properties? The difference in […]
What is the main role of operating system?
What is the main role of operating system? An operating system is the most important software that runs on a computer. It manages the computer’s memory and processes, as well as all of its software and hardware. It also allows you to communicate with the computer without knowing how to speak the computer’s language. What […]
What do you do if more light is needed to view the specimen?
What are the examples of positive feedback mechanism?
What are the examples of positive feedback mechanism? The release of oxytocin from the posterior pituitary gland during labor is an example of positive feedback mechanism. Oxytocin stimulates the muscle contractions that push the baby through the birth canal. The release of oxytocin result in stronger or augmented contractions during labor. What are examples of […]
Why do I have a voltage reading when light switch is off?
What is the transfer of energy through waves?
What is the transfer of energy through waves? ‘Wave’ is a common term for a number of different ways in which energy is transferred: In electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields. In sound waves, energy is transferred through vibration of air particles or particles of a solid through which […]

Is acetic acid and NaOH a buffer?
Is acetic acid and NaOH a buffer? Not a buffer; the NaOH completely neutralizes the acetic acid to give sodium acetate. Does HCl and acetic acid make a buffer? Hydrochloric acid (HCl) is a strong acid, not a weak acid, so the combination of these two solutes would not make a buffer solution. What makes […]
What is the displacement of the object during acceleration?
What is the displacement of the object during acceleration? Displacement equals the original velocity multiplied by time plus one half the acceleration multiplied by the square of time. Here is a sample problem and its solution showing the use of this equation: An object is moving with a velocity of 5.0 m/s. What is a […]
