When two equal and opposite forces act on an object, the object is said to be in a state of ___. A. motion. B. acceleration. C. equilibrium. D. deformation. 相关知识点: 试题来源: 解析 C。原因:当两个大小相等方向相反的力作用在物体上时,物体处于平衡状态。A 选项运动不符合这种情况;B...
英语翻译NEWTON Ⅲ:EQUAL AND OPPOSITE(作用力与反作用力)All objects,moving or at rest,obey Newton’s third law of motion,which holds that in nature,unaccompanied(无陪伴的) forces do not exist. 答案 牛顿第三定律:作用力与反作用力一切运动或静止的物体,都遵循牛顿第三定律,不存在单一的力使其维持运动...
When equal and opposite forces applied to a body 10 to along it it the stress so produced is called? Answer: When an equal and opposite force is applied to a rigid though merely elastic body, the stress produced is considered and known to be 'tensile stress'. When two equal opposite and...
Discusses the use of sub-atomic particle accelerators in physics research pertaining to the Standard Model of the universe and the Higgs boson. Mention of how machines such as the Large Hadron Collider and the Tevatron work; Political and technical reasons for choosing an electron collider over ...
1) Normal reaction N is equal to Mg 2) N does positive rotational work about the centre of mass 3) A couple of equal and opposite forces acts on the rod 4) All of the above A normal reaction N is equal to Mg B N does positive rotational work about the centre of mass C a ...
Step 5: Analyze the ForcesAs discussed, the forces acting on both blocks are equal in magnitude and opposite in direction:F1=kxandF2=−kxThus, the forces are equal and opposite, confirming that option C is correct. Step 6: Analyze the Linear MomentumFrom the conservation of momentum, we ...
Does an unbalanced force need to act upon an object, for the object to move, even though there are equal and opposite forces acting upon the object? If you double the force on an object but the distance remains the same, how much work is done on t...
25. Two equal forces acting on an object in opposite directions will be in equilibrium D A only if they act on the same point on the object. B if they are separated by a distance. C when they are balanced by a third force. D when their moments about the same point are equal. 相...
Newton's third law states that for every action done in this universe, there is equal and opposite reaction. Famous example is rocket which shoots upwards due to the thrust of hot gases coming out of rear. Key Ideas:A mass at rest on a ...
In order to establish the right to equal pay under the EA, a woman must identify a “comparator” of the opposite sex, who works in the “same employment” and then establish that she and the comparator are: employed on “like work”; or ...
