For the helicopter in the previous question, the tail rotor radius is 2.3 ft and the tail rotor is located 15.3 ft from the main rotor shaft. calculate the thrust and power required by the tail rotor for hovering conditions at sea level.

the results is a decrease in air temperature with an increase of altitude.

explanation:

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.

  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
