Answer: learn how to do it on your own idiot
Explanation: try hard in school
Answer:
- Distance is a scalar quantity, defined as the total amount of space covered by an object while moving between the final position and the initial position. Therefore, it depends on the path the object has taken: the distance will be minimum if the object has travelled in a straight line, while it will be larger if the object has taken a non-straight path.
- Displacement is a vector quantity, whose magnitude is equal to the distance (measured in a straight line) between the final position and the initial position of the object. Therefore, the displacement does NOT depend on the path taken, but only on the initial and final point of the motion.
If the object has travelled in a straight path, then the displacement is equal to the distance. In all other cases, the distance is always larger than the displacement.
A particular case is when an object travel in a circular motion. Assuming the object completes one full circle, we have:
- The distance is the circumference of the circle
- The displacement is zero, because the final point corresponds to the initial point
Answer:
<em>b) false</em>
Explanation:
The scale of a map is the ratio of a distance on the map to the corresponding distance on the ground. Scaling allow us to capture a large geographical area on a reduced platform while still retaining the relative sizes and positioning of places on the map to their real life sizes and positioning. If both maps cover a standard 8.5 by 11-inch sheet of paper, then the map with the smaller ratio will have the bigger geographical area.
To understand better, let us assume two geographical areas A and B. A is bigger than B. If we were to put them both on the same area of map paper, then we'll have to scale up the smaller geographical area B so as to fit into the map paper. This means that the geographical area with the smaller area B will have the larger scale on the map.
Electromagnetic waves going through outer space has the greatest speed among all kind of waves.
Option B
<u>Explanation</u>:
Electromagnetic waves are the waves that can go through the vaccum of space. Electromagnetic waves are made by the vibration of an electric charge. This vibration makes a wave that has both an "electric and magnetic nature". An electromagnetic wave transfers energy through a vaccum at a speed of 
(speed esteem ordinarily depicted by the sign c). The spread of an electromagnetic wave through a material medium happens at a net speed which is under .
