The path r(t)= (t-sin t) i +( 1 - cos t) j describes motion on the cycloid x=t-sin t, y=1- cos t. Find the particle's velocity and acceleration vectors at t equals pi, and sketch them as vectors on the curve.

the answer to your question is high voltage and high currency

  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

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
