Which of the following expressions will have units of kg⋅m/s2? select all that apply, where x is position, v is velocity, m is mass, and a is acceleration.

Explanation:

In the image  attached with this answer are shown the given options from which only one is correct.

The correct expression is:

Because, if we derive velocity with respect to time we will have acceleration , hence:

Where is the mass with units of kilograms () and with units of meter per square seconds , having as a result

The other expressions are incorrect, let’s prove it:

This result has units of

This result has units of

This result has units of and is a constant

This result has units of

This result has units of

This result has units of and is a constant

This result has units of and is a constant

because is a constant in this derivation respect to

This result has units of and is a constant

  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

explanation:

wheres the pic
