The elastic force exerted by the spring is: A. Proportional to the compression distance B. Inversely proportional to the compression distance C. Independent of the compression distance D. Zero 相关知识点: 试题来源: 解析 A。本题考查弹力的计算。根据胡克定律,弹簧的弹力与压缩或拉伸的距离成正比。
When a spring is compressed by a distance 'x', the potential energy stored is U1. It is further compressed by a distance '2x', the increase in potential energy is U2. The ratio of U1:U2 A1:7 B1:4 C1:8 D1:3Submit If the potential energy of a spring is V on stretching it by ...
The elastic potential energy of the springs at the instant when they are compressed 15 cm is A12.1×104 joules B121×104 joules C1.21×104 joules D1.21×106 joulesSubmit When a spring is compressed by a distance 'x', the potential energy stored is U1. It is further compressed by a ...
When the spring has to be compressed by applying some force on it then the work done in compressing the spring is stored in the spring as the spring potential energy which depends on the spring constant and the compression of the spring. For the...
Dfirst,the forces and time exerted on both blocks are the same,thus both blocks got the same impluse(Ft) at the moment the potential energy of the spring becomes 0.According to the Impluse-momentum theorem,the change in momentum equals to the impluse(p=Ft).the momentum p=mv and the kin...
The genome of an organism is inherited from its ancestor and continues to evolve over time, however, the extent to which the current version could be altered remains unknown. To probe the genome plasticity of Saccharomyces cerevisiae, here we replace the
Before consolidation, the hippocampal autoassociative network encodes the memory. A modern Hopfield network (MHN)63is used, which can be interpreted such that the feature units activated by an event are bound together by a memory unit64(seeMethodsandSupplementary Information). Teacher–student learning...
