take the volume that is submerged. That's the volume of water displaced.
but the volume of submerged is different in those two
so buoyancy force is different in those two
weights are the same
probably. since the densities* are different.
In question it says wights are the same and diffferent volumes
so it seems that the one with more density should have a lower buyonacy force
but you said that when an object floats the buoyancy force equals weight,so since both objects have the same weight,then buoynacy force should be equal in those two
The more dense object will float with a greater percentage of its volume immersed, not less.
2) If they have the same MASS, the more dense one will have less VOLUME
The answer is A. Solids have both definite shape and denfinite volume.
acceleration = velocity/time

Answer: option A) initially increases, then decreases.
Justification:
The increase of the rate of effective collisions among particles as the temperature increases is explained by the collision theory in virtue of the increase of the kinetic energy.
This is, as the temperature increase so the kinetic energy increase and the higher the kinetic energy the greater the number of collisions and the greater the chances that this energy overcome the activation energy (the energy needed to start the reaction).
Now, as the reaction progress the number of reactants particles naturally decrease (some of them have been converted into product) so this lower number of particles means lower concentration which means lower collisions and, thereafter, a decrease in the reaction rate.
