In <span>fiber-optic technology, optic fibers are being utilized in the transmission of light in between fiber ends. This improves communication for the reason that it can transmit signals in longer distances and higher bandwidths. In this case, the answer that supports this is the third option: the speed is increased as light travels through space.</span>

<h3><u>Answer;</u></h3>

It has allowed for faster transmission of Internet signals.

<h3><u>Explanation</u>;</h3>
  • <em><u>Fiber optics technology is a technology that uses glass threads to transmit data. </u></em>A fiber optic cable is made of a bundle of glass threads each capable of transmitting messages modulated onto light waves.

This technology has a number of advantages over electrical transmission which includes;  

  • <em><u>Extremely high band width; it can transmit a higher volume of data per unit time compared to other means.</u></em>
  • <em><u>Long distance; data can be transmitted over long distance compared to copper cables.</u></em>
  • <em><u>It has allowed faster transmission of data such as internet signals.</u></em>
  • <em><u>Low security risk and</u></em>
  • <em><u>Resistance to electromagnetic interference among others.</u></em>

Two forces act on an object. The first force has a magnitude of 17.0 N and is oriented 58.0º counter clockwise from the x-axis,
Inessa05 [86]

Answer:

option a is correct

net force = 28.7 N and 70º

Explanation:

given data

first force= 17.0 N

angle = 58.0º

2nd force = -19.0 N and 12.5 N

to find out

magnitude and direction net force

solution

we know here 1st force is at angle 58.0º is 17 N

so here x component of force is F1 cosθ and y component of force is F1 sinθ

so 1st force

x component of force =  F1 cosθ = 17 cos(58) = 9.0086 N    ...............1

y component of force = F1 sinθ = 17 sin(58) = 14.4168 N        ..............2

and 2nd force

x component of force =  -19 N                           .................3

y component of force = 12.5 N                          ..................4

so net force is

net force = √(Fx²+Fy²)

net force = √((9-19)²+(14.41+12.5)²)

net force = 28.7 N

and

magnitude

tanθ = Fy / Fx

tanθ = 26.92 / 10

θ = 70º

so option a is correct

The driver of a car slams on the brakes, causing the car to
zubka84 [21]

It takes 4.58 seconds for the car to stop and the initial speed of the car is 77.14 ft/s

<u>Explanation:</u>

Given:

Acceleration, a = -17 ft/s²

Distance, s  = 175 ft

Final velocity, v = 0

Time, t = ?

Initial speed, u = ?

We know:

v² - u² = 2as

(0)² - (u)² = 2 X - 17 X 175

u² = 5950

u = 77.14 ft/s

To calculate time:

v = u + at

0 = 77.14 - 17 X t

17t = 77.14

t = 4.58 sec

Therefore, It takes 4.58 seconds for the car to stop and the initial speed of the car is 77.14 ft/s

Calculate the speed of body moving a distance of 320km in 4h
ololo11 [35]
Convert km to m. -> 320km=320000 m
Convert hours to seconds -> 4 hrs=14400 s
Divide the distance by time because v=d/t
320000/14400=22.22 m/s
