With a 50g mass spring undergoes SHM with a frequency of 0.70 Hz how much work is done in stretching the spring 15 cm from its unstretched length and how much energy is then stored in spring?
The work done in stretching the spring can be seen as equal to the spring's newfound potential energy, i.e. V = 1/2*k*(x-x_0)^2 = 1/2*(w^2*m)*(x-x_0_^2) = 1/2*0.70^2*0.05*0.15 = 0.00184 [J]
What is an example of potential enrgy?
Examples of potential energy : 1. An object raised above the ground acquires potential energy equal to the work done against the force of gravity; the energy is released as kinetic energy when it falls back to the ground. 2. Similarly, a stretched spring has stored potential energy that is released when the spring is returned to its unstretched state.
Differentiate batween the work done on the body and work done by the body?
note: Work done is = force applied to a body * time taken by the body When we apply a force on to an object such that the object displaced in the direction of force, then some unit of work is done on the body. When a body sets another body into motion by applying a force, in unit time, that body is considered as it had done a unit of work
What is present when work is done?
In physics work is dome when a force acts on a body and the body moves in the direction of the force.
When do you say work is done?
Work done is zero when a body moves up a hill or climb an object and then descend. In moving a body Q from point B to a point A along a path X, a work is done which is equal to the potential energy gained by the body. If the body then goes back from A to B along a path Y, it loses the potential energy gained and so the total work done on the body becomes zero.
Is it good to stretch the rules at work to get things done?
There are different opinions about stretching rules, and most are likely to think it depends on what rules are being stretched.
How much work is done in stretching a spring from its natural length to 9 in. beyond its natural length when a force of 10 lb is required to hold a string stretched 5 in. beyond its natural length?
See http://answers.yahoo.com/question/index?qid=20080722222615AAcfBvp ; it is a similar question.
Is it normal for ear gauges to swell and hurt when you first stretch them?
Stretching done correctly using the proper method generally do not swell nor do they hurt when stretched. Using stretching claws will and can done serious damage to the tissue, generally due to the lack of restraint used by the individual who is stretching there piercings. Too far too fast is the number one cause of stretching issues and tissue tearing. If the piercing are swelling and sore you have gone too far too quickly. You should talk to your local professional body piercer who will explain the traditional method used for correct lobe stretching.

Stretching out ears?
Correct stretching of ear lobes involves a professional body piercer and a plan. Any good piercing studio will offer you a stretching plan saving you money and discomfort. The plan is simple, one gauge once every 30 days till you reach the desired size you want, this will allow you to get the stretching done without having to shell out for jewellery each time. Done by a professional body piercer you can be sure the stretch is done correctly and safely without worrying about tearing the lobe tissue. It's the smartest and safest way to get affordable stretching done and still being able to revert back to normal size lobes when you want to. Talk to your local professional body piercer for details.
Which type of stretching must be done under the supervision of a coach or a trainer?
dynamic stretching
Is dynamic stretching even considered a form of stretching or exercise If it is a form of stretching can it be done on a daily basis to help sore muscles?
Dynamic stretching should be done before activity as it helps to loosen muscles, relieving soreness and warming them up. Static stretching should be done after activity, making use of warm muscles to increase flexibility.

Is there any legal age restriction on ear stretching?
Not That I Know Of... I've Recently Stretched My Ear Up To An 8mm And I Was Able To Buy The Gear From My Local Place And I'm 15. I'm Not Sure About If You Went To Actually Have It Done Though. I Did Mine Myself. (: Hope I've Helped.
