The notion of potential energy is related to the work done by the forces on the physical system to move it from one position to another in space. That is to say in practical terms it can be calculated by the Force applied in a certain distance. Mathematically this is
Here,
PE = Potential Energy
W= Work
F = Force
d = Distance
Replacing we have,
Therefore the potential energy stored in the bow the moment before the arrow is released is 12J.
Answer:
Δt = 5.29 x 10⁻⁴ s = 0.529 ms
Explanation:
The simple formula of the distance covered in uniform motion can be used to find the interval between when the sound arrives at the right ear and the sound arrives at the left ear.
where,
Δt = required time interval = ?
Δs = distance between ears = 18 cm = 0.18 m
v = speed of sound = 340 m/s
Therefore,
<u>Δt = 5.29 x 10⁻⁴ s = 0.529 ms</u>
