A128 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 that 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?

Explanation:

Time Taken = Transmit + Propagation Delay

Propagation Delay = Distance/Speed of Light

Transmit = Size/Bandwidth

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

muscle endurance

explanation:

i can do 50 in a row ( but i get so tired after that)

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.
