What a pendulum is?
A system is a matter defined by the walls of space.
A surrounding is an environment around the system in observation.
A pendulum is a system containing the bob of the pendulum and the string to which the bob is attached.
The rest of the environment around the pendulum is considered as the surrounding.
The pendulum the student has chosen to study is a system.
Thus the correct answer is option a.
the unit of the measure =
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
