Earthquake is the continuous movement of the earths internal material, will produce a huge force acting on the rock layer, when this force accumulated to a certain extent, will make the rock layer rupture sharply, release huge energy to produce strong vibration, this is the earthquake. Earthquake...
Explain how a child's abilities become combined and coordinated during sensorimotor development. How does a child's physical movement foster his understanding and knowledge of the environment and the objects in it? Provide two examples that illustrate ...
Much like the high-pitched sound from a fire-truck siren gets lower as the truck moves away, the movement of stars affects the wavelengths of light that we receive from them. This phenomenon is called the Doppler Effect. We can measure the Doppler Effect by measuring lines in a star's sp...
Once aloft, gravity (the weight of the hang glider and pilot) pulls the glider back toward Earth and propels the glider forward, continually causing air to flow over the wing. In addition to the horizontal movement of air, hang gliders can get lift from rising currents of air, such as ...
Why is the tension force equal to mass x gravity on an inclined plane? How does acceleration depend on the net force? Is tension force negative? What is the tension in a rope being pulled from opposite ends with identical forces of 50 n?
Several them were believed to have been under the influence of alcohol — or suffered from a movement-restricting disorder that prevented them from moving quickly enough to escape the fire [source: Benecke]. Spontaneous Combustion The validity of spontaneous human combustion is viewed with skepticism...
[1]. The hands can stay on the athletes’ hips throughout the test or not, as both methods have shown good levels of reliability [2]. This test should incorporate various drop heights to assess at what height the athlete can elevate more his centre of gravity, and it was already proven...
These factors were distilled from the mathematics of organic forms, which prompted the evolution of the human brain so as to interpret environmental information for survival. In addition, some properties, such as sunlight, color, gravity, fractals, curves, detail, water, life, representation of ...
1. People can’t resist following the gaze of other people 2. People can’t resist seeing where an arrow points 3. People can’t resist following the “line of sight” of objects Now let me break this down for you: People are innately curious creatures, and that’s why we can’t re...
Future robots may need lighthearted physical interaction capabilities to connect with people in meaningful ways. To begin exploring how users perceive play
