Answer:
Repeaters
Explanation:
EMS are communication systems that coordinates emergency medical care among ambulances, 911 (telephone) dispatch centers, and hospital emergency departments. According to my research on EMS systems, I can say that based on the information provided within the question you would need Repeaters. These are a piece of hardware that repeats and extends a signal so that it reaches a greater distance.
I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
The copper is a conductor and the rubber is an insulator. Conductors allow electricity to be transmitted freely while insulators prevent most of the current from transmitting. The outer electrons of the conductor's atoms are not very stable and are able to freely move around the material. In a material such as copper, the valence electrons are essentially free and strongly repel each other. The atoms of insulators such as rubber, hold tight to their outer electrons which prevents electricity from flowing freely through.
Answer:
-194 m/s
Explanation:
We are taking as a reference point the position of the sun
In this case,
The spacecraft is moving with a velocity of +126 m/s
The asteroid is moving past in a backwards direction at 68 m/s relative to the spacecraft.
Speed of the asteroid - speed of the spacecraft = 68m/s
Speed of the asteroid = 68 m/s + 126 m/s
Speed of the asteroid = 194 m/s (backwards)
Beacuse the asteroid is moving in the opposite direction of the spacecraft
The asteroid has a velocity of -194m/s relative to the position of the Sun
