a box is a cube with sides of 0.155 m long. if it is completely underwater, what is the buoyant force acting on it?

36.5N

Explanation:

Given that the side length of cube (s) = 0.155m

The buoyant force also regarded as upthrust can be explained as the upward force exerted on by a fluid on an object immersed in it.

Buoyant force is calculated using the formula :

F = density × volume × acceleration due to gravity

Density of water = 1000kg/m^3

Volume of cube = s^3

Volume = 0.155^3 = 0.003723875

Recall:

density = mass / volume

Mass = density * volume

Mass = 1000kg/m^3 * 0.003723875m^3

Mass = 3.723875kg

Buoyant force or upthrust = weight of fluid displaced.

Weight = mass * acceleration due to gravity

Buoyant force = (3.723875 * 9.8)

Buoyant force = 36.493975

= 36.5N

if you answer my question i will answer yours

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
