chemical potential energy in the cart is converted to kinetic energy in the track

kinetic energy from the cart is converted to thermal energy in the track

kinetic energy from the cart is converted to chemical potential energy in the cart

what was the acceleration of the 2 kg cart?

⇒ 16.0 cm/s2

what was the acceleration of the 4 kg cart?

⇒ 8.1 cm/s2

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.

  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
