The rotor blade on the side of the helicopter that moving in the opposite direction?

The tail rotor is moving "perpendicular" to the main rotor, not "opposite".
The tail rotor creates thrust opposite to the thrust of the main rotor, to keep the fuselage from spinning.
Most helicopters spin the main rotor counter-clockwise looking from above, which puts a clockwise rotation on the fuselage. You need a tail rotor pushing the tail counter-clockwise to keep the fuselage pointed in the direction the pilot chooses.

Why is it necessary to have the tail rotor on the helicopter that spins perpendicular to the spin of the main rotor?
"For every action there is an opposite and equal reaction." For the helicopter to make the blade move in one direction, the blade will try to make the helicopter move in the opposite direction. Since the blade tries to make the helicopter spin, something is needed to keep the helicopter from spinning. So the manufacturer puts a tail rotor on the helicopter.
What happens to the advancing blade of a helicopter?
The "advancing blade" of a helicopter refers to the side of the rotor which moves forward in relation to the fuselage. As each rotor blade makes a full circle around the center, on one side of the swing, it moves forward, and on the opposite side it is moving towards the rear of the helicopter. When the helicopter is moving forward in air, the rotor blades on the advancing side are moving at a higher airspeed than the rotor blades elsewhere. Rotor speed + aircrafts forward airspeed. This results in slightly more lift on that side. Conversely the exact opposite is happening on the other side where you get Rotor speed - aircraft forward airspeed. This creates a tendency for helicopters to want to roll at high airspeed. This is one of the many odd tendencies of rotor aircraft that pilots are constantly adjusting to balance out.
What happens when the blade of a helicopter stops spinning in the sky?
Then the helicopter will crash.
Where is the centre of pressure on the main rotor blade of a helicopter?
In the centre of the rotor hub.
How does a helicopter stay in the air?
The source of lift force from the rotor (Rotation of two objects 'blade' creates a lifting force) blades allows the helicopter to stay in one area for extended periods of time. Each rotor blade, whether it is 2 or 7, has the ability to change pitch. This means the blade can rotate so that the nose or leading edge can tilt down or up. If it pitches up, the lift of the blade increases. Collective Controls As the blades rotate it produces lift. The pilot inputs controls that increases the pitch on all the blades at once. All the blades pitch up and produce more lift, so the helicopter rises. Cyclic Controls The pitch of the blades can also be controlled so that the blade pitches UP when it is on one side of the helicopter and pitches DOWN when it is on the other side. As the advancing blade is moving from rear to front, it decreases it Lift. Then as the blade moves to other side, it increases its Lift and pushes the helo through the air. In a simply explanation, this is what causes the helicopter to fly forward. Think of it like someone paddling a canoe. On many helicopters, the input is accomplished through the controls of the Swashplate. Custermen - Worked 11 years at Bell Helicopter.

Why almost all helicopters have a small tail rotor at the back?
when the main blade rotates it creates torque and if that torque is not countered by the rear rotor the helicopter will spin out and crash. the helicopters that do not have a rear rotor have another rotor that is the same size moving in the opposite direction
What is a blade from a helicopter in words?
The main blade on a helicopter is the 'rotor'

Which direction do you turn nut to remove saw blade on a 10inchtractor ryobi table saw?
any saw is the opposite of the way the blade spins!
What happens when the blade of a helicopter stops spinning in the sky?
Then the helicopter will crash.
Which way do you turn the bolt to remove the blade on a toro 36 inch walk behind mower?
The opposite direction that the blade rotates. In this case I would say counter clockwise but their should be a marking somewhere on the mower that shows blade rotation direction.
