Models that explain the formation of the solar system through a series of gradual steps are considered evolutionary theories. Wh
lora16 [44]

Answer:

Catastrophic theories

Explanation:

The theory of catastrophe is a collection of methods used to analyze and describe the ways in which a system can experience sudden significant behavioral changes when one or more of the variables that govern it are continuously modified.

Georges Louis de Buffon suggested in 1745 the first destructive theory — that a comet pulled material from the Sun to form the planets.

Therefore the answer is -

Catastrophic theories

A boy rows a rowboat across a river. The boat moves at 4.3 m/s at a direction of 25°
NikAS [45]

East component: 3.9 m/s

South component: 1.8 m/s

Explanation:

We have to resolve the velocity vector along the east and south axis.

Taking east as positive x-direction and south as positive y-direction, the components of the velocity are given by:

v_x = v cos \theta\\v_y = v sin \theta

where

v = 4.3 m/s is the magnitude of the velocity

\theta=25^{\circ} is the angle between the direction of the velocity and of the x-axis

Substituting into the equations, we find:

East component:

v_x = (4.3)(cos 25^{\circ})=3.9 m/s

South component:

v_y = (4.3)(sin 25^{\circ})=1.8 m/s
