还有个问题:EXPLAIN WHY FORCES ARE BALANCED OR UNBALANCED?为什么力是平衡或不平衡? 相关知识点: 试题来源: 解析 噢!这是化学反应热力学的问题.两种物质放在一起时,如果没有化学反应发生,那么它们各自都处在原有的“平衡”状态,没有所谓“力”的问题发生; 如果发生完化学反应之后,当然生成了新的物质,可是这种...
Balanced forces are where two forces of equal size act on an object in opposite directions. It means that in each direction, any pushes and pulls are balanced by another force in the opposite direction. In a balanced force, a body or an object continues to be in its position, i.e., i...
It is shown from all the above that the donor–acceptor CT complexes are primarily formed by the attractive Edisp and Ees between donor and acceptor molecules along the stacks. The attractive and repulsive intermolecular forces are balanced, with the highly directional nature of the Eex playing ...
You are being pulled down by gravity, and at the same time, the floor you stand on pushes back up on you. The reason you may not notice the forces is because they are balanced. This means that the forces are equal in size and opposite in direction. Read Forces: Balanced and ...

When theforces are balanced and aligned the aircraft is said tobe in equilibrium. There are two types offorces-static forces, dynamicforces. Weightis a static force it can be considered constantat any time. Thrustvaries with engine power, propeller rpm andairspeed but can be set at a ...
However, Fisherian sex-ratio selection, which favors a balanced sex ratio, is an opposing force. We show that the evolution of maternal sex-ratio biasing by these opposing selection forces requires a positive covariance across environments between the sex-ratio bias toward sons (b) and the ...
