Yo, help will give brainliest An un-stretched spring that is initially 20 centimeters long has a spring constant of 3.5 x 103 newtons per meter. What is the total length of the spring in centimeters when it is stretched to the point where 2.8 joules are stored in it?

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.

so easy. just google the electromagnetic waves and it’ll pop up.

  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

well clustered together.
