Electromagntic wave, such as an X-ray.
Explanation:
- Electromagnetic wave does not require any medium to travel. These waves propagate outwards from the source.
- They can travel even through the vacuum of outer space.
- The major source is the sun which emits radiation in the form of the Electromagnetic spectrum.
- These waves travel through oscillating electrical and magnetic fields generated by the oscillating charged particles.
- These waves oscillate in the perpendicular direction of planes concerning each other and are in form.
- Electromagnetic waves travel at speed of light.
Answer:
Mercator
Explanation:
One of the most famous map projections is the Mercator, created by a Flemish cartographer and geographer, Geradus Mercator in 1569.
Answer:
climate change threatens coastal areas which are already stressed by human activity pollution invasive species and storms sea level rise could be rolled and in coastal ecosystems and eliminate Wetlands warmer and more acidic oceans are likely to disrupt Coastal and marine ecosystems
Meteor = Space rock
Asteroids= small rocky object
Comets= ball of ice
Planet= travel around starts
Orbital radii= average distance from sun
A half-infinite line (also known as a half-line) with one of the two points and is commonly used to represent a ray. The endpoint of a ray is point S. The correct option is B.
<h3>What is a ray?</h3>
A half-infinite line (also known as a half-line) with one of the two points and is commonly used to represent a ray. It is assumed to be infinite.
Given that Two lines extend from point S to create a right angle. The vertical line extends from point S through point R. The horizontal line extends right from point S through point T.
Also, A third line extends right and up from point S through point U. This can be drawn as shown below.
Now, since all the ray starts from point S, therefore, the endpoint of a ray is point S.
