What effect does the buoyant force have on a submerged object? it causes a net force acting upward on the object. it causes the object to sink in a fluid. it causes the object to float in a fluid. it causes a net force acting downward on the object.

 The buoyant force is an upward force on an object submerged in a fluid. It is the resultant of the pressure force on the surface of the object. The buoyant force may be larger than the weight of the object causing it to accelerate upwards.

Conclusion:

The weight of the water displaced by the object is subtracted from the actual weigh of the object (out of water), leaving the object with a net positive weight while submerged.

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

b) mutualism

hope this : )
