Explicacion
m = 65 kg
g = 10 m/s²
r = 0.5 cm (1m / 100 cm) = 0.05 m
A = π r² = π (0.05 m)² = 0.00785 m²
F =W = m g = 65 kg(10 m/s²) = 650 N
P = F/A = 650 N / 0.00785 m² = 82802.54 N/m²

Answer:
Explanation:Hooke's law states that " if the elastic limit of an elastic material is not exceeded, the extension,e is directly proportional to the applied force or load.
<span>When an observer is moving towards a stationary object making a sound,
he runs the risk of startling the stationary object.
On the other hand, if the stationary object is the one making the sound,
then the pitch of the sound perceived by the observer is higher than the
sound that the object is actually making.</span>
