In aircraft design, the pressure coefficient C p is usually measured during wind tunnel testing of an aircraft component to predict structural loads, as well as lift and drag forces. Let 2 0.5 p p p C V −  = , where V is the airspeed of the test at pressure p and using a fluid of density  . The pressure difference p p −  is measured where p is located at a point on the surface of the test component. Estimate the uncertainty in C p under the following conditions: 2  = − = p p p 1000 N/m , 2 up =15 N/m ; 3  = 1.20 kg/m , 3 u = 0.01 kg/m ; V 50.0 m/s  = , 0.21 m/s V u  = . Assume 95% confidence in stated values.

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27

neither accurate nor precise.

  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
