Why did people reject the theory of continental drift? The main reason that Wegener’s hypothesis was not accepted was because he suggested no mechanism for moving the continents. He thought the force of Earth’s spin was sufficient to cause continents to move, but geologists knew that rocks are too strong for this to be true. […]
What makes a bad experiment?
What makes a bad experiment? Bad experiments move metrics by confusing or tricking your users. They make things harder for your users, rather than solving underlying problems. Good experiments are conceived as bets. You know they have a chance to fail, but based on the info you have available, it is a good investment to […]
How do you remove a magnetic field?
How do you remove a magnetic field? The magnetic field can be removed from a magnet by applying a reversed magnetic field to the magnet. This can be accomplished by passing an alternating current through an alternating current through a component of the magnet. What can stop a magnet from working? The forces of attraction […]
Do objects stick together in an inelastic collision?
Do objects stick together in an inelastic collision? People sometimes think that objects must stick together in an inelastic collision. However, objects only stick together during a perfectly inelastic collision. Objects may also bounce off each other or explode apart, and the collision is still considered inelastic as long as kinetic energy is not conserved. […]
Why does an intermediate level of disturbance promote species diversity?
Why does an intermediate level of disturbance promote species diversity? At high levels of disturbance, due to frequent forest fires or human impacts like deforestation, all species are at risk of going extinct. According to IDH theory, at intermediate levels of disturbance, diversity is thus maximized because species that thrive at both early and late […]
Who benefits from taking supplements?
Who benefits from taking supplements? 3 Groups Who Really Can Benefit from Vitamin Supplements Vitamin and mineral supplements do not prevent death or chronic diseases, according to a new scientific article, but some groups can still benefit. Multivitamin and mineral supplements are virtually universal in America. Vitamin D for the Sun Deprived. Vitamin B12 for […]
What is the potential difference across the capacitor in a CR circuit?
What is the potential difference across the capacitor in a CR circuit? The capacitor is uncharged, so its potential difference is zero. The closed switch has no potential difference, so by the loop rule the potential difference across the resistor equals the emf of the battery. What is the potential difference across the 6.0 ΜF […]
What exercises not to do with bad knees?
What exercises not to do with bad knees? The worst exercises for knee joints for people with bad knees include full-arc knee extension including using the machine at the gym, full-deep lunges, deep squats, and Hurdler’s stretches, because these exercises place excessive strain on the knee joints and can increase pain and cause injury. What […]
What are 2 key theories of color vision are they contradictory or complementary?
What are 2 key theories of color vision are they contradictory or complementary? The opponent-process theory shows that we have opponent-process cells in the retina and thalamus for red-green, yellow-blue, and white-black. These theories are complementary and outline the two stags of colors vision: (1) The retina’s receptors for red, green, and blue respond to […]
Does light year and wavelength have same dimensions?
Does light year and wavelength have same dimensions? Solution : Light year and wavelength both represents the distance, so both has dimension of length not of time. Do stress and Young’s modulus have same dimensions? Young’s modulus is the ratio of stress, which has units of pressure, to strain, which is dimensionless; therefore, Young’s modulus […]
