When Jeremy returned home after vacation, he noticed that his new plant had not grown. His mother, a florist, told him that it w
as because the plant was not getting enough sunlight. He moved his plant closer to the window to get more sunlight. How can Jeremy best support the idea that his plant needs more sunlight? Ask his mother to make the plant better. Wait and see what happens to the plant. Remove the plant from direct sunlight after a week. Ask his science teacher at school what she thinks could be the reason.
<em>The best course of action for Jeremy would be to wait and see what happens to the plant after moving it closer to the window to get more sunglight.</em>
If the plant grows after observing it for some times, he can conclude that light has been a major hindrance to the growth and more sunlight would benefit the plant. If the observation is otherwise, then Jeremy can conclude that the lack of growth observed is not due to light.
I'll start with the distance covered while decelerating. Since you know that the initial speed of the car is 15.0 m/s, and that its final speed must by 10.0 m/s, you can use the known acceleration to determine the distance covered by
on one side of the equation and solve by plugging your values
To get the time needed to reach this speed, i.e. 10.0 m/s, you can use the following equation
The solubility of a solute becomes weaker and changes it’s solid state when heated because it causes the molecules to dissolve faster. If the solution was cooled, it would begin to regain its solid form as it’s molecules would be slowing down. I hope this helps!
