The kinetic energy of the shopping cart increases. This speeds up the energy rate of friction between the wheel and the floor giving off more kinetic energy so the speed rate can increase (depending on how much your pushing it) Hope this helps :)
I know for a fact that a good conductor transfer electricity well,.. so my guess would be that the answer is true.
Answer:
powdered sugar
Explanation:
The higher is the exposed area of sugar, the faster is the dissolution process. Thus, to choose between the different types of sugar, we have to look at the volume occupied by the sugar.
In sugar cubes, the particles of sugar as compacted in a cube, so the particles inside the cube are not exposed to the solvent (water). So, sugar cubes have the slowest dissolution process. Then, in granulated sugar, the particles have more area exposed, so this type of sugar will dissolve faster than sugar cubes. Finally, powdered sugar is composed of tiny particles with more are exposed, so powdered sugar has the fastest dissolution process.
Therefore, powdered sugar will dissolve the fastest.
I don't care but one another time and I have any questions about this email
Complete Question:
A soccer player pumps air into a soccer ball until no more air can be pushed inside.Use the particle model to predict what will happen if a sharp object creates a hole in the soccer ball.
Answer:
particles will rush out of the ball until the pressure is equal inside and outside the ball
Explanation:
We need to understand when a ball is pumped with air until no more air can be pushed inside, that the particles inside the ball are closer together and bounce into each other more than the particles outside the ball and this makes the pressure inside the ball greater than that outside.
Now when a sharp object creates a hole in the soccer ball the particle move from a place of high pressure to a place of lower pressure because the force at the place of high pressure overpowers the force at the place of lower pressure.
