The Sound of Silence: How Gravity Created a Terrifying Score for Outer SpaceAngela Watercutter
选项中的关键信息分别是not used to the low-gravity environment、difficult to figure out where they were、the space in the cage too small和not sensitive to the changed environment,因此,听录音时应重点关注They具体做了什么事情或者具有哪些特征。讲话中提到,在实验开始的时候,老鼠看起来显然很不舒服。它们...
when you get to the open space, put your hands on your head. When you are in school, you have to follow your teachers instructions. At home at school when you cant run out to the toilet, or squat under the corner, it is best to hide in a narrow space, the most triangular area. ...
(absent) of gravity in space,astronauts usually sleep in a sleeping bag and have to attach themselves (3) to avoid (avoid) floating around.Their main task inside the space station is to conduct scientific research and with the space station (4) ...
To help the astronauts adapt, NASA, as part of their training, subjects the astronauts to such an environment every day. The enclosed region of “zero” gravity is not located in space, but iscreated right here on Earth. The question is… how does NASA achieve this?
That's why we need to look at Einstein's later theory, theGeneral Theory of Relativity, which describes how gravity affects the shape of space and flow of time. Imagine a stretched-out sheet. If you place a bowling ball in the middle of the sheet, the sheet will warp as the weight ...
It is a vast galaxy, a large system that includes stars, gas (predominantly hydrogen), dust and dark matter, all bound together by gravity. As we navigate through the cosmos, an intriguing enigma emerges: What is the Milky Way truly like? What is it composed of, and what is its shape...
The amount of drag is proportional to the airspeed of the hang glider: The faster the glider moves, the more drag it creates (see How Gliders Work for details). How a pilot maneuvers a hang glider As with soarplane gliders, the balance of these three forces (lift, drag, gravity) ...
FAQ: How Does Acceleration Affect Perceived Gravity in Space? How is g-force calculated? G-force is calculated by dividing the acceleration due to gravity (9.8 m/s^2) by the acceleration of the object. Can humans survive high g-forces? Yes, humans can withstand up to 9 g's for a ...
The focus is on the lignin, the tough plant wall substance that allows plants to defy gravity and grow upright. Scientists will study how the plants respond to the weightless conditions of the space station. For instance, will the plants still grow "up" even in a microgravity environment?
