when the earthquake happen we should hide under the furniture which are very solid(坚固的).Second,we should keep calm,and dont worry about it.Third,we should make sure that the door is open so as to escape.Besides,we should prepare something which we must carry when the earthquake...
These proportionalities can be expressed by the formulag=m/r2, wheregis the surface gravity of Mars (expressed as a multiple of the Earth’s,which is 9.8 m/s²),mis its mass – expressed as a multiple of the Earth’s mass (5.976·1024kg) – andrits radius, expressed as a multiple...
Lack of gravity in outer space poses significant challenges when performing everyday tasks. An astronaut's work is not restricted to when he or she is in space, according to NASA. "When astronauts are not flying on a mission or training for a mission, they support other...
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 ...
Humidity is a key factor in weather forecasts, indoor comfort and even health. There are various ways to measure humidity, each providing different insights into the amount of moisture in the air. Water Vapor and Its Role Water vapor plays a vital role in the Earth’s weather and climate ...
Before we look at how aerodynamics is applied to automobiles, here's a little physics refresher course so that you can understand the basic idea. As an object moves through the atmosphere, it displaces the air that surrounds it. The object is also subjected to gravity and drag. Drag is ge...
