If the swimmer could cross a 14 km channel maintaining the same average velocity as for the first 50 m in the pool, how long wou

alukav5142 [94]

Complete question:

If the swimmer could cross a 14 km channel maintaining the same average velocity as for the first 50 m in the pool, how long would it take?

For the first 50m in the pool, the average velocity was 2.08 m/s

Answer:

It would take for the swimmer approximately 1.87 hours.

Explanation:

If the swimmer maintains the average velocity on the channel, we should find and approximate value of the time it takes to cross the channel with the Galileo’s kinematic equation:

$x=vt$

With x the displacement, v the average velocity and t the time, solving for t:

$t=\frac{x}{v}=\frac{14000m}{2.08\frac{m}{s}}$

$t=6730.7 s= 1.87 h$

All object changes are compared with a ____ , which is an object that appears to stay in place?

Kaylis [27]

Answer:

All object changes are compared with a <em>reference</em> , which is an object that appears to stay in place.

Explanation:

In scientific experiments, the changes in the experimental object are observed by comparing the changes with a reference object. In the reference object, no changes are made and conditions are kept normal in it. For example, if we want to measure the distance of two cars from a point, the point will be the reference point from which the distance shall be measured. Hence, all changes are made by comparison from a reference object or point.
