A 128 kbs point to point link is set up between Earth and a rover on Mars. Use the distance between Earth and Mars as 55Gm and t

hat data travels over the link at the speed of light, 3x108 m/s. A camera on the rover takes pictures of its surroundings and sends the pictures to Earth. The pictures are 5 Mb in size. How long would it take a picture to reach the Earth?

Answer:

Explanation:

Time Taken = Transmit + Propagation Delay

Propagation Delay = Distance/Speed of Light

= \frac{55\times 10^9}{3\times 10^8}\\\\= 183.334 seconds

Transmit = Size/Bandwidth

=\frac{5\times 10^6}{128\times 10^3}\\\\= 39.062 seconds

So, Total time = 183.334+39.062 = 222.396 seconds.

Only two horizontal forces act on a 3.0 kg body that can move over a frictionless floor. one force is 9.0 n, acting due east, an
Zolol [24]
The first thing you should do for this case is to find the horizontal and vertical components of the forces acting on the body.
 We have then:
 Horizontal = 9-9.2cos (58) = 4.124742769 N.
 Vertical = 9.2sin (58) = 7.802042485 N
 Then, the resulting net force is:
 F = √ ((4.124742769) ^ 2 + (7.802042485) ^ 2) = 8.825268826 N
 Then by definition:
 F = m * a
 Clearing the acceleration:
 a = F / m
 a = (8.825268826) / (3.0) = 2.941756275 m / s ^ 2
 answer:
 The magnitude of the body's acceleration is
 2.941756275 m / s ^ 2
