hello how are u
Hi
Because over a certain limited range, a carefully manufactured and very expensive spring will stretch exactly in proportion to the magnitude of the force that's causing it to stretch, and the magnitude of the force can be accurately determined simply by observing and measuring the length of the stretch.
the last spring tide was in the year 2013.It occur during a new or a full moon
3 cm for every 1 pound 15 cm for 5 pounds
W = (1/2)kx^2 W = (1/2)(12.3)(.252)^2 //Convert cm to m W = 0.39Nm = 0.39J
A spring is a season.A spring is a source of water.A spring is a coil of metal.A spring is a leap.The word spring is also a verb: spring, springs, springing, sprang, sprung

The force you are exerting to stretch it, and the restoring force of the spring.

When you pull on the scale you stretch the spring the pointer on the scales moves as you pull to measure the force you are using you have to be able to lift or pull on the spring scale
Measure how many newtons of pull you need in order to stretch the springtwo centimeters longer. Then the spring constant is1/2 of (that number of newtons) per centimeter, or50 x (that number of newtons) per meter.======================================US, Liberian, and Burmese version:Measure how many ounces of pull you need in order to stretch the springone inch longer.Then the spring constant is (that number of ounces) per inch .
That depends on the spring.
elaborate
A spring has maximum potential energy at maximum displacement from equilibrium. This means that the greatest potential energy will occur when a spring is stretched as far as it will stretch or compressed as tightly as it will compress. In an oscillating system, where an object attached to a spring is moving back and forth at a given frequency, the object will oscillate about the equilibrium point, and the potential energy of the system will be greatest (and equal) when the object is farthest from equilibrium on either side.
It depends on spring energy or spring strength
Yes
since the springs share the load the stretch displacement is load divided by the sum of the spring constants. If the springs are identical the stretch is one half of the stretch with only the one spring, or 2.5 cm
do your homework yourself. You may acually learn something interesting :) For this problem, think of the ratio between the two masses to find the answer
