A boat going from salt water (sg = 1. 03) to fresh water (sg=1. 0) sinks 7. 82cm and after burning 72,730kg of coal rises up by 15. 24cm. Find the original displacement of the boat in seawater in kn

Respuesta :

The original displacement of the boat in seawater in km is 7.42 x  10⁻⁵ km.

What is displacement?

The shortest path traveled by any particle during its motion.

A boat going from salt water to fresh water sinks 7. 82cm. After burning coal, the boat rises up by 15. 24cm.

Displacement = 15.24 -7.82 = 7.42 cm

1cm = 10⁻⁵ km

So, 7.42 cm =7.42 x  10⁻⁵ km

Thus, the original displacement is 7.42 x  10⁻⁵ km.
