The mathematical relationship between force and extension for a spring is F = -kx , where F is the restoring force, k is the spring constant and x is the extension. If a box that weighs 40 N is hung from a spring of content 400 N/m, then the extension is equal to x = -F / k = -400 / 40 = -10 cm. The negative sign simply shows the extension and restoring force are in opposite directions. The answer is 10 cm.
Since it travels 220,000,000 miles per hour then it is 220000000 divide 120 minutes makes one hour =1833,333.333 miles per minute and so divide by 60 seconds which makes one minute = 30,555.55556 and because it says five seconds it is 152777.7778
Answer:
. The SI unit of volume is the cubic meter (m3), which is a derived unit.
Liter (L) is a special name for the cubic decimeter (dm3).
