Answer to: A spring has a force constant of 8.1 N/m and a rest length of 0.30 m. How much force must be applied to stretch the spring to a length...
These properties apply wholly to an ideal spring, and – to some extent – to springs used for all manner of purposes in the real world. Most other objects behave differently; those that rigidly resist deformation usually break when an applied force becomes strong enough, while others may stret...
Learn how to find the effective spring constant of a set of springs in parallel, and see examples that walk through sample problems step-by-step for you to improve your physics knowledge and skills.
As fresh food stores leave a neighbourhood, residents find it harder to eat well and stay healthy. Food deserts are linked with lower local health outcomes, and they may be a driving force in the health disparities between lower- income and affluent people in the US. Until recently, the iss...
弹簧的力常数为150牛/Cm,a,将弹簧从原位置拉60毫米需要多大的功 F*S=900J B再拉7.6毫米需要再做多少功=114J 算的不知道对不对哈 ，数学好久没学了哈哈
The elderly are very valuable members of our club and provide a large number of services. They often overlook and avoid it. This is an important treatment for the elderly, with love and respect. It is not only their retribution, but also a driving force for us to learn and grow. The ...
