Pls help quickly average velocity = u+v/2 or displacement/ total time taken

Average velocity = u+v/2

Explanation: The definition of velocity is displacement over time taken. That is,

Velocity = displacement/ time taken

But we have initial velocity U and final velocity V. When we are talking about average, we are talking about the mean value of the given parameters.

Therefore, average velocity will be addition of initial velocity and final velocity divided by 2. That is,

Average velocity = (U + V)/2

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.

  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
