The circumference of the circle after t seconds = 25.12 t
Given data,
The radius of each circular wave will increase by four centimeters per second (cm/s)
In 1 second of circular wave radius = 4cm
In 1*t second of circular wave radius = 4t cm
As a result, the radius of the circular wave after t seconds is 4t cm.
We already know that the circumference of a circle is given by = 2πr, where r is the circle's radius.
As a result, the radius of a circular wave after t seconds is = 2π * radius of a circular wave after t seconds = 2π * 4t
= 8πt
( Taking π = 3.14 )
As a result, the circumference of the circle after t seconds = 8πt
= 3.14t
= 25.12t

Complete question:
A 0.50 kilogram frog is at rest on the bank surrounding a pond of water. As the frog leaps from the bank, the magnitude of the acceleration of the frog is 4.0 meters per second^2. Calculate The magnitude of the net force exerted on the frog as it leaps.
Answer:
2.0N
Explanation:
Given that,
Mass, m of the frog = 0.5 kg
The acceleration of the frog = 4.0 m/s².
We have been asked To find,
The magnitude of the net force exerted on the frog as it leaps.
So
We calculate this using the formula below :
F = ma
When we insert the values into the formula, we have:
F = 0.5 kg × 4 m/s²
F = 2.0 N
Therefore, the magnitude of net force is 2.0 N.
The difference between sublimation and condensation is that
Sublimation is used to in a separation technique to separate sublime substance from a mixture while condensation is the
is the process where water vapor becomes liquid
<h3>What is separation technique?</h3>
This technique is used in chemistry to separate two or more constituents from a mixture
In conclusion, sublimation differs from condensation because sublimation is used to in a separation technique to separate sublime substance from a mixture while condensation is the
is the process where water vapor becomes liquid
