attractive force- the force by which one object attracts another attraction affinity- (immunology) the attraction between an antigen and an antibody bond,chemical bond- an electrical force linking atoms force- (physics) the influence that produces a change in a physical quantity; "force equals mass...
A formation of fibrous aggregates of plate-like gold particles dispersed in an aqueous solution was observed under an optical microscope. The suspension of gold particles, which were about 2 μm in diameter and 100–200 Å in thickness, was prepared by reducing a dilute chloroauric acid ...
How does the value of gravitational force F change between two objects? Newton's Law of Gravitation: Between any two objects with mass, there is always an attractive force acting between them. This attractive force is called the gravitational force. The gravitational force between two o...
The gravitational force between two bodies is : Aalways repulsive Balways attractive Cattractive only at large distances Drepulsive only at large distances.Submit Assertion : Gravitational force between two masses in air is F. If they are immersed in water, force will remain F Reason : Gravitat...
the attractive forces between nearby stars balanced by the repulsive forces from those that were farther away. However, we now believe such an equilibrium would be unstable: if the stars in some region got only slightly nearer each other, the attractive forces between them would become stronger ...
5.The painting ___ (以大自然的美为基础)is attractive. 6.Some videos have been banned ___(基于……对的考虑) that they are too violent. 7.The man ___ ( 留胡子 ) is a chairman of a committee and he is___ (极忙碌) and has no time to have a rest. Last week he broke down ...
When the position is such that neither side will gain by making the first move, it is called temporizing ground. 7. In a position of this sort, even though the enemy should offer us an attractive bait, it will be advisable not to stir forth, but rather to retreat, thus enticing the ...
Go 10 times farther away and the force drops by 10 x 10 = 100 times.如果距离变为10倍，引力就会减弱10 x 10 = 100倍。Gravity is also attractive: It can only draw things in, not repel them.引力还有吸引的方向性：只能把物体拉向自己，而不是排斥它们。But how it attracts things is where ...
were glued to a chamber in place of attractor flies, they failed to attract the free-moving flies, suggesting that the attractive action of subject flies is goal-oriented, instead of purely exploratory, and is performed to move close to other flies, but not non-fly objects (Supplementary Fig...
There happened a quarrel between Agamemnon and Achilles in the final year of the war because Agamemnon stole an attractive slave called Briseis, one of the war prizes, from Achilles. Achilles, the greatest warrior of the age, once withdrew from battle in response to Agamemnon's supposedly evil...
