Environment related opportunities for service include lake cleanup. The correct option among all the options that are given in the question is the first option or option "a". There are several other types of services also related to environment. I hope that this answer has come to your help.
Answer:
it helps researchers sense things on earth. they are usually on aircraft or in a satellite.
Explanation:
it collects data from a different level detecting the energy from the earth. this energy comes naturally from the earth's surface. it even most commonly picks up reflected sun light (which is also a source of radiation)
Answer:
A sensitive infra-red telescope
Explanation:
Infrared light is highly advantageous for astronomers as it helps in discovering and studying the astronomical objects that are observed in the night sky.
This infrared light is commonly used in the telescopes to study the distant stars, and by analyzing them, they are classified as different types like L or M types. These telescopes, by using the infrared light, it is able to detect the presence of stars and other astronomical bodies, and this type of telescopes helps in determining the temperature of the distant objects such as the stars, planets, and other objects.
Answer:
C. P waves move matter back and forth, in a direction parallel to the direction of the wave, while S waves move matter up and down, perpendicular to the direction of the wave.
Explanation:
P and S - waves are both called seismic waves. They are produced during deformation within the earth.
Usually, P or Primary waves have the fastest velocity and arrives at the seismic station first. Secondary, Shear or S-waves follows P-waves.
- P-waves are body waves that propagates within a body. They cause movement internally.
- Secondary waves are surface waves. They move on the surface of earth.
- One way to also distinguish between these two seismic waves is that, P-waves are longitudinal waves that travels parallel or longitudinally to the source.
- Secondary waves moves in an up and down motion pattern. They propagate transversely to their source.
