The time taken for the sailfish to reach the herring if it is 55.0 m away is 2.7 s.

<h3>Time of motion of the star fish</h3>

The time taken for the star fish to travel the given distance is calculated as follows;

s = ut + ¹/₂at²

55 = 11.8t + (0.5)(6.39)t²

55 = 11.8t + 3.195t²

3.195t² + 11.8t - 55 = 0

<em>solve the quadratic equation using formula method,</em>

where;

a = 3.195, b = 11.8, c = -55

t = 2.7 s

Thus, the time taken for the sailfish to reach the herring if it is 55.0 m away is 2.7 s.

Process by which water vapor changes to a liquid
OverLord2011 [107]

The correct answer to the question is B) Condensation.

EXPLANATION:

Before coming into any conclusion, first we have to understand various phase changes.

There are various phase changes in which matter in one state is converted into matter in another state.

Evaporation: Evaporation is the thermal process of state change in which a liquid is converted into corresponding vapor state.

For instance, water to steam or vapor.

Condensation: Condensation is just the opposite process of evaporation. In this process, a substance in vapor phase is converted into liquid phase.

For instance, water vapor to liquid water.

The two processes that is Convection and radiation mentioned in the question are not phase changes. These two are different modes of heat transfer between substances.

Hence, the process by which water vapor changes to a liquid is called condensation.
