Sally Sue, an enthusiastic physics student enjoyed the opportunity to collect data from standing waves
in a spring. She and her partner held the ends of their spring 4.00 meters apart. There were 5 nodes
in the standing wave produced. Sally moved her hand from the rest position back and forth along the
floor 20 times in 4.00 s. Sketch the situation and determine the following:

a. the wavelength of the wave Sally Sue sent

b. the frequency of the wave produced

c. the speed of the wave

i think the answer would be b

  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

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
