A pendulum is made up of a metal cylinder of diameter d attached to a thin string. The pendulum passes through a photogate at the lowest point in its motion, as shown in the side view. The photogate measures the time t it takes the cylinder to pass through the photogate. Using this information, the mechanical energy of the system is obtained at its lowest position. The speed of the pendulum is calculated as dt. If the motion of the pendulum does not oscillate perpendicular to the photogate, as shown in the top view, how will this affect calculated total mechanical energy?.

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.

  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
