Disturbance in particle motion parallel to the wave velocity is called a longitudinal wave. Disturbance in particle motion perpendicular to the wave velocity is called a transverse wave.

The distance and displacement are the same when the displacement is parallel to itself or straight. Displacement is a vector and distance is a real number or scalar. If an object is displaced around a circle the displacement is zero and the distance is 2pi r.
The sound coming from the bell, and the vibration of the bell itself, is described as simple harmonic motion. The graph would be a diminishing sine wave.
A person who studies time travel or time altering is known as a Chronoportationologist. The study of time itself is called Horology. Or more simply put they would be called a Time Travel Studier.
The crayfish has a pair of legs called chelipeds, more commonly known as pinchers. The joint motion of these pinchers allow the crayfish capture prey and defend itself.
The compass needle aligns itself parallel to the direction of the lines of magnetic force where it happens to be. It does not 'point to a particular pole' for that is beyond the sensibility of a simple bar of metal. I repeat, it aligns itself parallel to the lines of magnetic force ...
Transverse waves oscillate perpendicular to the direction of energy propagation. Think of one wave by itself. Which direction is it propagating? Some direction parallel to the surface of the water. Now think of one particular piece of water that the wave passes through. It's motion goes upwards and downwards, which is perpendicular from the surface of the water, therefore transverse. Waves oscillating parallel to the direction of energy propagation are called longitudinal.
the manjira itself vibrates to produce sound
Two lines are not parallel if they have exactly one point in common; otherwise they are parallel. So this means a line is parallel to itself!
Normally 2 equidistance lines are needed to designate them as parallel lines. If we say parallel lines, we mean different lines. However, we can say that the line can be parallel to itself if we move it to another dimension. For example, if the line lives in 2D, we can paralleled move it it in the 3D space, and move it again where it was, or vice versa. The beauty is that this line has a unique position on the plane, but in 3D it has infinitely many positions without breaking the condition, the same direction.
Light travels in the direction it was emitted. Light cannot steer itself towards any particular object.
No: lines can be parallel and two (or more) rectangles in 3-d space can be parallel but a rectangle, by itself, cannot be parallel.
When a magnet is freely suspended at its center it will set itself along the north-south direction. The tip pointing towards the geographical north direction is called the north pole and the other tip is called the south pole.
False.
It is a circle drawn around the globe parallel to the equator and at right angles to the meridians.
The direction itself is a noun. It is only an adjective when placed before a noun (e.g. west wing).
y = -5x + 9 is the equation of a straight line. It cannot be parallel or perpendicular by itself, you need another line to compare it to.
