(a)
<span>F= qE </span>
<span>F sin 30.0° = mg </span>
<span>= 0.0026(10) </span>
<span>= 0.026 N </span>
<span>F = 0.052 N </span>
<span>E = F/q = 0.052 / 60µ = 867 N/C </span>
<span>(b) </span>
<span>T = F cos 30.0° </span>
<span>= 0.0450 N</span>
Answer:
Thats the third law______
An object that is in free fall seems to be (D) weightless.
Objects which are in free fall are said to be weightless because they only have the force of gravity acting upon them. Objects in free fall do not experience air resistance.
Answer:
The correct option is: d. Fiber-optic
Explanation:
A fiber-optic cables or an optical-fiber cable is a cable that is composed of a bundle of optical fibers. These cables are used for transmitting information or digital signals over long distances.
Each optical fiber in an optical-fiber cable is individually coated with a protective plastic cover and contained in a protective tube. Therefore, an optical-fiber cable is not affected by any electromagnetic interference or radio frequency interference.
