for a moving object distance covered by it is always greater than or equal to the displacement of the object in a given time. ex
AleksandrR [38]
<h3><u>Answer</u></h3>

  • Distance is equal to the Total Distance covered by a body, from the initial till the final point.

  • Displacement is equal to the shortest distance between two points.

  • So we known that Distance can only be equal to or greater than the displacement and can never be shorter than the displacement.

  • This is just common sense how can anything be shorter than the shortest path itself. But it can be equal to the shortest path
<h3>━━━━━━━━━━━━━━</h3>

<h3><u>Know </u><u>More</u></h3>

☯ Distance is a scalar quantity and has only magnitude but no direction.

☯ Displacement is a vector quantity and has both magnitude and direction.

☯ Distance can only have +ve values whereas displacement can be +ve, -ve or even be zero.

Jupiter, the largest planet in the solar system, has an equatorial radius of about 7.1 x 10^4km (more than 10 times that of Eart
Zarrin [17]

Answer:

The average speed is v  = 1260 \  km/s

The average speed is different from the average velocity in this question

Explanation:

From the question we are told that

   The equatorial  radius of Jupiter is  R_j = 7.1*10^{4} \  km

   The period of oscillation of Jupiter is T_J = 9 \ hours , 50 \ min = 35400 \  seconds

Generally the average speed is mathematically represented as

      v  = \frac{2 \pi * R_j }{T_J}

=>   v  = \frac{2 *3.142  * 7.1*10^{4} }{35400}

=>   v  = 1260 \  km/s

Generally in average speed the direction is not considered while in average velocity the direction is considered for the  case of this question the movement equitorial point has no direction in that it start from one point and after its periodic motion it still remains at that point

Volcanoes that have fast flowing liquid lava will be narrow like a river
vodomira [7]

Answer:

Shield volcanoes, the third type of volcano, are built almost entirely of fluid lava flows. Flow after flow pours out in all directions from a central summit vent, or group of vents, building a broad, gently sloping cone of flat, domical shape, with a profile much like that of a warrior's shield.
