Aboat has a mass of 6800 kg. its engines generate a drive force of 4100 n due west, while the wind exerts a force of 800 n due east and the water exerts a resistive force of 1200 n due east. what are the magnitude and direction of the boat’s acceleration?

The boat's acceleration are:  a= 0.3 m/s² in west direction.

Explanation:

Fm= 4100 N

Fwi= 800 N

Fwa= 1200 N

Fm - Fwi - Fwa= m *a

clearing a:

a= 0.3 m/s²

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.

truck y has a greater velocity than truck x.
