C 5 a What causes the pressure of air at the Earth's surface? b State the equation linking pressure difference, height, density and gravity.
c. At the Earth's surface, atmospheric pressure is 10% Pa and the density of air is 1.3 kg/m3. Use this information to calculate the height (or depth) of the atmosphere.
d. Suggest one reason why you may have underestimated the height of the atmosphere.

can someone please help i got exams tomorrow

i guess it’s a and b

  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

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
