For a huge luxury liner to move with constant velocity, its engines need to supply a forward thrust of 6.85 105 N. What is the magnitude of the resistive force exerted by the water (in N) on the cruise ship?

The magnitude of the resistive force exerted by the water is newtons.

Explanation:

By First and Second Newton's Law, the resistive force exerted by the water on the cruise ship has the same magnitude of forward thrust, with which it is antiparallel to. The equation of equilibrium for the luxury liner is:

(Eq. 1)

Where:

- Forward trust, measured in newtons.

- Resistive force exerted by the water, measured in newtons.

From (Eq. 1), we get that: ()

The magnitude of the resistive force exerted by the water is newtons.

empty space could also be a simple vacuum

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
