What is spatial polarization? The polarization process is likely to deepen urban socio-spatial divisions in two ways: the proportions of low- and high-income neighbourhoods can increase in the poorer and better-off parts of the city, respectively. Also, the social distance between these two parts, in absolute terms, can become more extreme. Do you think globalization […]
How big of a telescope do you need to see planets?
How big of a telescope do you need to see planets? Telescopes that have 4 or 5 inch diameters are great for viewing solar system objects like the planets, our Moon, and Jupiter’s moons. Viewing Neptune and Uranus can be difficult with a scope this small but it’s not impossible. A telescope of this size […]
What is the intensity for muscular endurance?
What is the intensity for muscular endurance? For experienced lifters who want to improve their muscular strength, aim for 8–12 reps per set for 2–4 sets, with a 2- to 3-minute rest between sets. To improve your muscular endurance, do 15–20 repetitions at no more than 50% of your 1RM, with a 2- to 3-minute […]
When two waves interfere destructively what changes?
When two waves interfere destructively what changes? This is known as destructive interference. In fact, if the two waves (with the same amplitude) are shifted by exactly half a wavelength when they merge together, then the crest of one wave will match up perfectly with the trough of the other wave, and they will cancel […]
How can you tell if your 02 sensor is bad?
What is the meaning of angle of incidence and angle of reflection?
What is the meaning of angle of incidence and angle of reflection? At the point of incidence where the ray strikes the mirror, a line can be drawn perpendicular to the surface of the mirror. The angle between the incident ray and the normal is known as the angle of incidence. The angle between the […]
What is the force acting on the ball?
What is the force acting on the ball? The forces are the weight, drag, and lift. Lift and drag are actually two components of a single aerodynamic force acting on the ball. Drag acts in a direction opposite to the motion, and lift acts perpendicular to the motion. What is the action force acting on? […]
What rate is the length of the shadow changing?
What rate is the length of the shadow changing? We’ve determined the instantaneous rate of change in the position of the shadow, which is -160 ft/sec, but that figure changes dramatically as the bird moves closer to the ground (and the mouse). In which case the length of the shadow of the tree will be […]
What is the difference between subduction zones and hot spots?
What is the difference between subduction zones and hot spots? Subduction zones are areas in which oceanic plates are overridden by continental plates, forcing the heavier oceanic crust deep enough to be melted and recycled as second generation magma. Hot spots provide information about the rates and directions of movement of tectonic plates over geologic […]
What is the relation between frequency and wavenumber?
What is the relation between frequency and wavenumber? Frequency is a measurement of the number of wave cycles per second. Wavenumber is the reciprocal of the wavelength multiplied by a constant. Although they look the same, the difference is that wavenumber has nothing to do with the velocity of the wave- wavenumber is measured in […]
