If the Sun were to turn into a black hole, or be replaced by a black hole
with the same mass as the Sun, then Earth would continue to orbit it
as usual. (But it would be very cold and dark around here.)
Friction is used to refer to forces that resist relative motion, in general,whereas viscosity refers specifically to resistive forces that occur between layers of a fluid when fluids attempt to flow. Fluid friction is the force that resists the movement of a solid object through a fluid(liquid or gas). Sky divers falling down through the sky experience a type of fluid frictioncalled air resistance.
Answer:
Work is the energy transferred to or from an object via the application of force along a displacement.
Air resistance is a type of friction.
Hope this helps! :D
The airplane is traveling 620mph, or 620m/60 minutes
Divide 270 by 60 to find the number of hours the plane is flying.
270/60 = 4.5
The plane will fly for 4.5 hours. Speed * time = Distance (make sure units are the same)
620mph*4.5hr = 2,790 miles
