The material that the snails are moving on affects their speed. On a smooth material, (petri dish) the snails moved the fastest. On a rough material (sandpaper) the snails moved the slowest. On dirt, a compromise between smooth and rough, the snails moved at a medium pace. The material and possibly friction affect this.
Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion.
BUT
Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position. so here distance is 40 m but displacement is obviously zero meter. so answer is 0 more information on: https://www.physicsclassroom.com/class/1DKin/Lesson-1/Distance-and-Displacement
Satellite (moon) revolve around the planet
But planet revolve around the sun.
Ganymede is a satellite(moon) which revolve around the planet jupiter. So, it is considered as moon not planet.
Simple theory.
Answer:
Acosθ
Explanation:
The x-component of a vector is defined as :
Magnitude * cosine of the angle
Maginitude * cosθ
The magnitude is represented as A
Hence, horizontal, x - component of the vector is :
Acosθ
Furthermore,
The y-component is taken as the sin of the of the angle multiplied by the magnitude
Vertical, y component : Asinθ
