Answer:
Part 1
Multiply both sides by 2π
2πf = √(g/L)
Square both sides
4π²f²= g/L
Invert both sides
1/(4π²f²) = L/g
Multiply both side by g
g/(4π²f²) = L
We usually write an equation with the subject (L) n the left
L = g/(4π²f²)
________________________
Part 2
Using the above equation with the given values:
L = g/(4π²f²)
. .= 9.8 / (4π² x 1.6²)
. .= 0.097m (= 9.7cm)

By the way, where it says
“f=1.6 then there are 2 beats a second, or 192 beats per minute (bpm).”
this should say
“f=1.6 then there are 3.2 beats a second, or 192 beats per minute (bpm)”
Step-by-step explanation:
By calculating monthly incom and debt the 2nd one
Answer:
19.6 miles in 12 minutes.
Step-by-step explanation:
first take 60, then divide it by 12.
60÷12=5
then take 98 and divide that by 5
98÷5=19.6
By definition, the circumference of a circle is:
The area of a circle is:
Where,
r: radius of the circle.
When the radius is double, then the new area is:
Rewriting we have:
In terms of a we have:
Answer:
The new area of the circle in terms of a is:
Answer: The answer is just 24.3 miles.
The questions asked "How long was the ride from Kiley's house to the airport?"
The first sentence of the problem reads "They drove 24.3 miles from their house to the airport in an hour". The rest of the information isn't necessary to find this answer.
