AI Thread Summary
To determine if a stack of quarters from a filled closet would be taller or shorter than the Empire State Building, first calculate the number of quarters needed to reach 1,250 feet using the height of a quarter, which is 1/8 inch. Next, visualize the closet's dimensions (4' x 7' x 8') and calculate how many quarters can fit in a grid formation on the floor, considering the diameter of the quarter (15/16"). Multiply the number of quarters that can fit in each dimension to find the total. Compare this total to the number of quarters needed to see if the stack exceeds the height of the Empire State Building. This approach will provide a clear answer to the problem.

I received this problem in 8th grade goemetry today, and its due tomorrow. i have looked at it for 2 hrs now and STILL can't think of how to figure it out. help PLEASE?
Here it is:
If you filled a closet with stacks of quarters from floor to ceilling and then put all the quarters in one big stack, would it be taller or shorter than the Empire State Building?
Closet Floor=4' x 7' Height=8'
Empire State Building= 1250'
Width of Quarter= 1/8''
Diameter of Quarter= 15/16"

Well you can first determine the # of coins required to stack up to the Empire State Building. You have the overall height and the height (what you call the width... which is incorrect, its actually the height) of a quarter. Figure out how many of those 1/8" are in the 1250' of the building and you will have the # of quarters necessary.

Then visualize putting every quarter down in a grid formation on the closet floor. Using the diameter of the quarter, you can use each dimension of the closet floor to determine how many quarters can be stacked in each of the dimensions. Multiply those 3 dimensions and see if it comes out to more or less then the # of quarters necessary to be taller then the building.
 
i will try that.
 
Thread 'Voltmeter readings for this circuit with switches'
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
Thread 'Struggling to make relation between elastic force and height'
Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
