A child pulls on a wagon with a horizontal force of 75 N. If the wagon moves horizontally a total of 42 m in 3 minutes. What is the average power generated by the child

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.

explanation:

f=ma newton's second law 7x8=56n

iron would move it is magnetic there is a mag field around the current in the wire

  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
