Bikash T. Magar • asked a question

A helicopter flies off, its propellers rotating. Why doesn't the body of the helicopter rotate in the opposite direction?

In the air, there's nothing holding the body of the helicopter still - so the rotor blades spin one direction, but the torque applied to spin the rotors tries to spin the body of the helicopter in the opposite direction. The little rotor on the tail helps keep the body of the helicopter pointed in the same direction.

The Rh factor(the Rhesus factor or Rh antigen), is a protein that can be found on the surface of red blood cells. It is one of the most important blood group systems in human blood typing. The presence or absence of the Rh factor is denoted as either Rh-positive (+) or Rh-negative (-).

The Moon

Silent and still, the moon shines bright
In the dark, clear sky
Peaceful and calm, the night
A soothing balm to the weary eye

The moon, a glowing orb of light
Illuminates the path ahead
As the night wind whispers through the trees
And the stars twinkle overhead

So let us lay down and rest
And let the moon and night provide
The peacefulness and solitude
That we all need to feel alive
