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。
A block with mass m =7.1 kg is hung from a vertical spring. When the mass hangs in equilibrium, the spring stretches x = 0.23 m. While at this equilibrium...

short-term changes in weather patterns can have dramatic effects: an early frost in a citrus-growing region could cause a severe drop in that year's crop while less snowfall in a mountain region could mean a spring drought in surrounding valleys that depend upon the melted water for crop ...
The value of such a capacitor, essentially it’s “spring constant” for the mechanically–minded, is approximated by the formula in Figure 1 when the separation distance between the plates is small relative to their area. It should be noted however, that mechanical spring constants and ...

The result is a new generation of urban consumers. Businesses of all kinds spring up to provide goods and services to these consumers. Over time, a larger middle class of artisans and shopkeepers emerges. A large working class also emerges, and conditions were often much harsher for them. The...
