Q4: Consider the two vectors A=(7i-7j)m, B= (-14i-5j)m. Calculate: (a) A+B (b) A-B (c) |A+B| (d) |A-B| (e) A. B​

number of electrons for neutral cl

  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

t = 1/400 h   ⇔ 0.0025 h ⇔ 9s ⇔ 0.15 m

any of the answers are correct.
