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!

After first week pond will be:
10 + 10* 0.03 = 10*(1.03) feet deep
after second week it will be:
10*(1.03) + 10*(1.03)*0.03 = 10*(1.03)^2
from this we can conclude that after x week its will be:
10*(1.03)^x
Note that when second week starts our starting pond is already greater by 3%. every week we add 3% of prevous weeks size of pond
for x = 8 we get
f(x) = 10*(1.03)^8 = 12.66 or rounded 13 feet
Answer is D.
Answer:
Step-by-step explanation:
Two angles are Adjacent when they have a common side and a common vertex (corner point) and don't overlap.
If you were to write each of these using <, >, >=, or <=, you get the following:
A. >= 50
B. < 50
C. >50
D. <50
As you can see, the answer is A. At most 50, because 50 is included in the answer
