Answer=B and D
Both are types of potential energy that involve stored energy.
Hello!
The potential energy means it causes the object to slow down on the ramp. Potential energy generally means to slow an object.
Thank You!
Answer:
Using the molarity of the solution
Explanation:
The concentration of the two solutions can be compared by the use of the number of moles of solute present in each of the solutions. The solution with a higher molarity will be concentrated while the solution with a lower molarity will be dilute.
Explanation:
you are to see cells By doing an experiment.
By crushing a solid into a powder you increase the reaction rate (the chemical reaction rate). By crushing into a powder, you are increasing the surface area, increasing the exposure to the chemical reaction. The smaller the particles, the faster the chemical reaction that will take place. Think about an ice cube put in a pot of boiling water. The whole ice cube will take longer to melt than if you first crushed that ice cube into small pieces. Small pieces of ice put into boiling water would melt very quickly.
Hope this helps!! :)
