An airplane is flying in a horizontal circle at a speed of 480 km/h if its wings are tilted at angle =40° to the horizontal, what is the radius of the circle in which the plane is flying? assume that the required force is provided entirely by an "aerodynamic lift" that is perpendicular to the wing surface.

Explanation:

When wings of the airplane makes an angle of 40 degree with the horizontal so here we can say that force due to air is having two components

now we know that

also we know that

now plug in all data in above equations

  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
