Doubling which quantity would cause the largest increase in a spring’s elastic potential energy?

potential energy is maximum when streach distance of string is doubled

Explanation:

we know that elastic potential energy of a spring is given as

..................(1)

here k is spring constant

and x is stretched distance of spring

if we double the spring constant then potential energy will be given as

...............(2)

similarly if we double the stretch distance then potential energy in spring will be given as

.............(3)

from equation 2 and equation 3 it is clear that

it means potential energy is maximum when stretch distance of string is doubled

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
