I Believe the answer to your question is True.<span />
In addition to gravity, muscular peristaltic waves, originating in the renal pelvis, squeeze urine down the ureters and squirt it into the bladder, the peristaltic movements consist of radially symmetrical contractions and in the relaxation of the muscles that propagate in a wave downwards in the muscular tube, in an antegrade manner, such movements are also found in the esophagus and stomach.
Distance travelled by Bob was 7 meters and the displacement was 5meters.
<h3><u>Explanation:</u></h3>
Distance is defined as the total length of the path travelled by a body from its initial position to final position. Displacement on the other hand is defined as the length of the straight line joining the initial position and the final position of the body.
Here, Bob travelled from point A to point C via point B which took him to travel more distance. The length of distance from point A to B is 4 meters and from point B to C is 3 meters. So the total distance covered is
meters = 7 meters.
While the length of path straight from point A to C is 5 meters. So displacement is 5 meters.
