What does the skater physically do to make themselves spin faster or slower? The principle of the conservation of angular momentum holds that an object’s angular momentum will stay the same unless acted upon by an outside force. This explains why a figure skater spins faster when she tucks her arms in close to her […]
What is called dynamo effect?
What is called dynamo effect? Dynamo Effect. The dynamo effect is a geophysical theory that explains the origin of the Earth’s main magnetic field in terms of a self-exciting (or self-sustaining) dynamo. The electric current, in turn, produces a magnetic field that also interacts with the fluid motion to create a secondary magnetic field. What […]

Which soil has highest porosity?
Which soil has highest porosity? Clay What increases the porosity of soil? Usually, this is as simple as thoroughly mixing in organic material such as peat moss or garden gypsum to increase soil porosity. What are the factors that affect porosity? On the whole, porosity is directly dependent on the initial water content, temperature, pressure, […]
What causes perturbation?
What causes perturbation? Gravitational attraction is a main cause of perturbations. In the solar system, for example, the primary motion of planets and comets in their elliptical orbits is due to the sun. Perturbations are due to the attraction of the various other members of the system for each other. What is perturbation effect? Perturbation […]
What is the difference between SX and ox?
What is the difference between SX and ox? In other words, σx is the exact standard deviation of the data given (with n in the denominator), and sx is an unbiased estimation of the standard deviation of a larger population assuming that the data given is only a sample of that population (i.e. with n-1 […]

What is T1 and T2 in NMR?
What is T1 and T2 in NMR? The decay of RF-induced NMR spin polarization is characterized in terms of two separate processes, each with their own time constants. One process, called T1, is responsible for the loss of resonance intensity following pulse excitation. The other process, called T2, characterizes the width or broadness of resonances. […]
What is the largest crustal plate?
What is the largest crustal plate? Pacific Plate What are the biggest plates? The largest plates are the Antarctic, Eurasian, and North American plates. Plates are on average 125km thick, reaching maximum thickness below mountain ranges. Oceanic plates (50-100km) are thinner than the continental plates (up to 200km) and even thinner at the ocean ridges […]
What are emotions in communication?
What are emotions in communication? Emotions result from outside stimuli or physiological changes that influence our behaviors and communication. Emotions developed in modern humans to help us manage complex social life including interpersonal relations. The expression of emotions is influenced by sociocultural norms and display rules. What words will you use to encourage someone who […]
