The experiment about gravity ___ the object will fall faster if the mass is larger. A. prove B. proves C. proved D. proving 相关知识点: 试题来源: 解析 B。解析:主语The experiment是单数,所以谓语动词用第三人称单数形式proves。反馈
Calculate the force of Earth's gravity on a spacecraft 12,800 km (2 Earth radii) above the Earth's surface if its mass is 1,050 kg. The mass of an object at the earth's surface is 100 kg. Calculate the for...
The centre of mass of a body lies View Solution The line joining the centre of gravity of a cuboid and the centre of the Earth will fall within the base of the body even after being disturbed by an external force. Then the body is said to be in ___. View...
According to the fundamental principle of dynamics, the resultant force on an element is proportional to its acceleration (Newton's second law), the constant of proportionality being equals to the amount of matter of the element (i.e., its mass)....
Answer to: If the Reynolds number increases, will the following properties increase or decrease? 1. boundary layer thickness 2. shear stress 3...
This is because mass is an intrinsic property of matter and does not depend on the gravitational field or location. Step 3: Calculating Weight- Weight: The weight of an object is defined as the force exerted on it due to gravity, calculated using the formula: W=m⋅g where W is the ...
If Earth were twice its size, you'd be heavier, because the force of gravity increases as the planet's density and radius increase. It would take more energy to resist gravitational pull, so the structures we have today wouldn't be strong enough to stand as tall as they do now. Get...
If a significant fraction of heavy components is present in the natural gas mixture, laboratory measurements of () of the C7+ fraction are required to use mixing rules.A、the molecular weight B、mole fraction C、gravity D、critical temperature E、critical pressure暂无...
Related: Why is the speed of light the way it is? Most humans can handle acceleration forces of about four to six times that of gravity (4 to 6 g) for a short period of time. As the g-force increases, your body's ability to circulate your blood from your feet to your head become...
The weight?Gravity:In reference to the Gravity, the bending of the space-time because of the mass of the lump imposes a force of attraction over the other lump which is also present in the space-time. Heavier the lump is, more will be the force of attraction....
