What is the mechanical advantage of a ramp 8 m long that extends from the sidewalk to a 45633 m high porch?
Zero: the ramp cannot be shorter than the height to which it is suppose to reach. I suspect there is a missing decimal point.
How can height affect the time for an object to fall?
The acceleration of gravity is 32 feet per second, per second. This means that --eliminating any obvious aerodynamic considerations as there would be with, say, a feather -- the speed at which an object falls increases proportionately to the time it is falling. An object falling from a greater height will be falling for a longer time period and thus will reach a higher velocity and impact the ground with a greater force than one falling from a lower height.
Which is greater 0.088 or 0.109?
0.109 > 0.088 0.109 is greater than 0.088 ! It's greater because is closer to reach 1.

If i didn't take full advantage of my growth spurt does that mean i will not reach my full height potential?
Yes
How does the starting height affect the total time the marble rolls?
The starting height of the marble affects its initial speed, which in turn influences the time it takes to reach the bottom. A marble starting from a higher height will have a greater initial speed and reach the bottom faster compared to a marble starting from a lower height.
What does stop height mean?

What age do most girls reach their full height?

What is the height of a ADA compliant wall Telephone?
The ADA states: Side-reach Telephone: The Maximum height is 54". If side-reach Occurs over an obstruction 24" wide and 34" high, the maximum height allowed is 46" Forward-reach Telephone: The maximum Height allowed is 48". If forward-reach Occurs over an obstruction 20"to 25", the maximum height allowed is 44"
A certain tree duoubled its height every day it took100 days for the tree to reach its full height How many days did it take it to reach half its full height?
99 days
When You Drop An Object From A Certain Height It Takes Time T To Reach The Ground With No Air Resistance. If You Dropped It From Three Times That Height How Long Would It Take To Reach The Ground?
When an object is dropped from a certain height, the time it takes to reach the ground is independent of the height (assuming no air resistance). Therefore, whether you drop the object from three times the initial height or the original height, it will still take the same time (T) to reach the ground.

What would happen if the projectile were thrown with a greater velocity?
If the projectile is thrown with a greater velocity, it would travel further and potentially reach a higher peak height. The increased velocity would also result in a shorter flight time and the projectile hitting the ground with a greater impact force.
Average reach of teenagers?
The average reach is approx. the height of the boxer. Example, if a boxer is 6 feet tall, which is 72", then average reach would be 72".
