A spring has a spring constant of 50 N/m. How much force is required to stretch the spring by 2 m? A. 100 N B. 110 N C. 120 N D. 130 N 相关知识点: 试题来源: 解析 A。Force = Spring constant×displacement = 50×2 = 100 N. Option B, C and D are incorrect....
A spring has a spring constant of 50 N/m. How much force is needed to stretch the spring by 2 meters? A. 100 N B. 80 N C. 120 N D. 150 N 相关知识点: 试题来源: 解析 A。解析:Force = spring constant×displacement. 50 N/m×2 m = 100 N. Option B, C and D are ...
A spring with a spring constant of 50 N/m is stretched by 0.5 m. What is the force exerted by the spring? A. 25 N B. 50 N C. 100 N D. 125 N 相关知识点: 试题来源: 解析 A。根据胡克定律 F = kx,其中 k 为弹簧常数,x 为伸长量。所以 F = 50 × 0.5 = 25 N。
