The Hubble Space Telescope was released from the Space Shuttle, which was in a circular orbit at 400km earth altitude. The relat
snow_lady [41]

Answer:

d = (75 i ^ + 93 j ^ + 27 k ^) m ,  d2 = (900 i ^ + 1116 j ^ + 324 k ^) m

Explanation:

The two objects are in circular orbit together, therefore with the same angular velocity, after the launch they move with the relative velocity, so we can use the kinematic relation

       

         v = d / t

         d = v t

Reduce time to units SI

         t = 5 min (60 s / 1 min) = 300 s

X axis

         x = vₓ t

         x = 0.25 300

         x = 75 m

Y axis  

        y = v_{y} t

        y = 0.31 300

       y = 93 m

Z axis

        z=  v_{z} t

        z = 0.09 300

       z = 27 m

       d = (75 i ^ + 93 j ^ + 27 k ^) m

For the time of 1 h

       t2 = 1 h (3600s / 1 h) = 3600

       x2 = 900 m

       y2 = 1116 m

       z2 = 324 m

      d2 = (900 i ^ + 1116 j ^ + 324 k ^) m

If a wire carrying current causes the needle of a compass to move:
Alecsey [184]

Answer:

D. it demonstrates electromagnetism.

Explanation:

If a wire carrying current causes the needle of a compass to move, it is an example of electromagnetism.

The interaction between electric and magnetic fields is termed electromagnetism.

  • Electromagnetic interaction is usually induced between a wire and bar magnet.
  • With right set up magnetic and electrical fields can be induced using a magnet and current carrying wire.
