An airplane wing is designed so that the speed of the air across the top of the wing is 297 m/s when the speed of the air below the wing is 209 m/s. The density of the air is 1.29 kg/m3. What is the lifting force on a wing of area 26.0 m2?

The value is  

Explanation:

From the question we are told that

   The speed of air across the top of its wings is  

   The speed of air below  its wings is

    The density of air is

     The area of the wing is  

Generally the lifting force is mathematically represented as

Here   is the difference in kinetic energy density between the top and the bottom  

=>    

=>    

So  

=>

explanation:

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.
