Answer:
Alright well use long addition to to evaluate which gives you
7391.574 Hope this helps :)
Step-by-step explanation:
I will help up you using these statements which I took for the same problem:
a) at the lowest position of the bob, the KE is equal to zero.
FALSE BECAUSE AT THE LOWEST POSITION THE PE IS THE LOWEST AND THE KE IS THE HIGHEST.
b) at the highest position of the bob, the PE is equal to zero.
FALSE BECAUSE AT THE HIGHEST POSITION THE PE IS THE HIGHEST
c) at the highest position of the bob, the KE is equal to zero.
TRUE: AT THE HIGHEST POSITION THE PENDULUM COMES TO ZERO SPEED AND SO THE KE IS ZERO.
d) at all the positions except the highest positions the PE is zero.
FALSE: THE PE ENERGY CHANGES WITH THE ALTITUDE AND IS ZERO ONLY AT THE BASE LEVEL.

Step-by-step explanation:
Answer:
Each side of the original square is One-fourth the length of each side of the scale model
Step-by-step explanation:
Given that the square is a scaled copy of a smaller orginal square that was scaled up using a scale factor of 4, it means that the side length of the original square was multiplied by 4 to get the new side lenght of the scaled copy given in the question, which is 8ft.
Let original lenght be x.
x * 4 = 8 ft
4x = 8
x = 8/4 = 2.
Side lenght of the original square = 2 ft
Side of the original square to side of scale model = 2 ft to 8 ft = 2/8 = ¼.
Therefore, the statement that is true is: "Each side of the original square is One-fourth the length of each side of the scale model".
