Carbon cycle am pretty sure it that
Explanation:
The same thing happened in pressure cooker but the temperature inside is most higher.
hope you like my answer
thank you
Since it is given that their particles have a large difference in size, we can conclude that the particles of small size get embedded into the space between the particles of large size. Thus it doesn't increased it volume as it should have.
Two copper spheres are currently 1.2 meters apart. One sphere has a charge of +2.2•10-4 C and the other has a charge of -8.9•10-4 C, then the the force between the charged spheres is the force attractive.
<h3>What is Coulomb's law?</h3>
Coulomb's law can be expressed as that the electrical force between two charged bodies is directly proportional to the product of the quantity of charge on the bodies and inversely proportional to the square of the separation distance between the two bodies.
As given in the problem two copper spheres are currently 1.2 meters apart.One sphere has a charge of +2.2•10-4 C and the other has a charge of - 8.9•10-4 C.
As per coulomb's law, opposite charges attract each other.
Thus, If one sphere has a charge of +2.2•10-4 C and the other has a charge of -8.9•10-4 C, then the the force between the charged spheres is the force attractive.

Answer:
Box A
Explanation:
Let mass of each wooden box =m
Density of box A=
Density of box B =
Density,
Density of inversely proportional to volume.
The volume of box with smaller density is larger than the volume of box with large density.
When the boxes are submerged under water.
Then, the buoyant force=
Where V=Volume of displace fluid.
Density of fluid
Buoyant force of box A=
Buoyant force of box B=
Force=Buoyant force
Acceleration is directly proportional to volume.
Therefore,the box with large volume has greater acceleration.
Hence, the box A has greater acceleration.
