Question

Astronaut A can cover 10 meters per minute walking with the heavy shovel. What does

Answer 1

Answer:

d) The speed of the astronaut

Explanation:

The sentence describes the speed of the astronaut. This speed value is 10meters per minute.

Now let us understand why;

• Speed is the distance divided by time. It is a scalar quantity without regard for direction but it has magnitude.
• The value 10meters per minute clearly shows this instance. We do not know the direction the astronaut is moving towards.
• Velocity, like speed is the displacement of a body with time. It is a vector quantity and it shows the direction of motion.
• For example, 10m/s due west is a velocity value because we know the direction.

Therefore, since there is no directional sense, the value indicates speed.
