Does speed bend space? Since in the observer’s frame they are stationary and the Sun is moving, the conclusion is that velocity does not change the spacetime curvature. Incidentally, this is why a fast moving object does not turn into a black hole. Can we bend space? As the astrophysicist Geraint Lewis from the University […]
What is the parallelogram method?
What is the parallelogram method? Briefly put, the method involves drawing the vector to scale in the indicated direction, sketching a parallelogram around the vector such that the vector is the diagonal of the parallelogram, and determining the magnitude of the components (the sides of the parallelogram) using the scale. What is a 3d parallelogram […]
Does NaCl or CaCl2 have a higher osmotic pressure?
Does NaCl or CaCl2 have a higher osmotic pressure? NaCl dissociates into two ions, but calcium chloride (CaCl2) dissociates into three: one calcium ion and two chloride ions. Consequently, all else being equal, a solution of calcium chloride will have a higher osmolarity than a solution of sodium chloride. What is an example of osmotic […]
Which of the following is an operational definition of aggression?
Which of the following is an operational definition of aggression? Aggression: Any instance of Richard making physical contact with another person using his body or an object with enough force to cause an audible sound and/or leave a visible mark on the skin. Examples Include: Biting- teeth making contact with any part of the skin, […]
Which type of current makes a transformer work?
Which type of current makes a transformer work? alternating current What is the EMF equation of a transformer? Therefore, RMS value of emf per turn = 1.11 x 4f Φm = 4.44f Φm. This is called the emf equation of transformer, which shows, emf / number of turns is same for both primary and secondary […]
What is an example of retinal disparity?
What is an example of retinal disparity? Notice the little house is visible from the perspective of the right eye but not the left. Another well-known example of the use of retinal disparity is in motion pictures. It is becoming ever more popular for movie trailers to advertise that a movie is in 3D. This […]
Why was pink A Boy Color?
Why was pink A Boy Color? The reason is that pink, being a more decided and stronger color, is more suitable for the boy, while blue, which is more delicate and dainty, is prettier for the girl.” Additionally, a 1927 issue of Time noted that large-scale department stores in Boston, Chicago, and New York suggested […]
What is the mass of 5 moles of Fe2O3?
What is the physical meaning of Fermi level?
What is the physical meaning of Fermi level? “Fermi level” is the term used to describe the top of the collection of electron energy levels at absolute zero temperature. This concept comes from Fermi-Dirac statistics. The Fermi level is the surface of that sea at absolute zero where no electrons will have enough energy to […]
What is the peak of the wave?
What is the peak of the wave? Peak – the highest point above the rest position. Trough – the lowest point below the rest position. Amplitude – the maximum displacement of a point of a wave from its rest position. Wavelength – distance covered by a full cycle of the wave. Usually measured from peak […]
