Thus, by inserting the low k spring into the box, it would extend by large amounts, as the masses are added, until it reaches the rigid box where it can no longer extend.<br /><br />At this point, the spring inside the boss can no longer extend and the mass it supports is no longer small. Only the lower spring would. However, since this spring has a high k, it would extend by small amount at these larger values of masses.<br /><br />In the case of C, large masses would also result in high sensitivity since the spring with low k is outside the box and would extend by large amount.<br />Adminhttps://www.blogger.com/profile/03708185681043991662noreply@blogger.comtag:blogger.com,1999:blog-2214461049219354662.post-55081829637156148422018-02-10T20:15:37.413+04:002018-02-10T20:15:37.413+04:00Q 760) Do mind explaining a bit more as to why opt...Q 760) Do mind explaining a bit more as to why option A is correct and not C?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2214461049219354662.post-90491307065533727062017-05-22T16:12:29.837+04:002017-05-22T16:12:29.837+04:00This blog is very useful.
