Step-by-step explanation:
Given
See attachment for complete question
Required
Calculate distance FC
FC is calculated as:

Where


Considering
, we have:
--- Pythagoras theorem
Where



and



So:




Take square roots of both sides

So:

Considering
, we have:
--- Pythagoras theorem
Where:
and 
So, we have:



Take square roots of both sides

So;

Recall that:



The tension in the string balances out, and thus equals the centripetal force of the ball
T = mv^2/r
<span>
if it only takes half the time to finish one orbit it has to be moving at twice the original speed. </span>
<span>
And since v is squared T will increase by 4 </span>
<span>
T' = m(2v)^2/r </span>
<span>
T' = 4mv^/r = 4T </span>
<span>
T' = 24.0 N
I hope my answer has come to your help. Have a nice day ahead and may God bless you always!

Answer:
<h2>
12.5 units
</h2>
Step-by-step explanation:
Given figure : Trapezoid
Base sides,
a = 2.5
b = 7.5
Height ( h ) = 2.5
Now, finding the area:

Plug the values

Calculate the sum

Reduce the numbers with G.C.F 2

Calculate the product

Hope this helps...
Best regards!
I’m sorry I can only answer number 3. The coordinates should be 1,-5. I am really not sure tho, because I have never done anything like this
