Permanent press setting is hotter than normal setting
Answer:
U= 4.1×10^{-3} J
Explanation:
Given:
Young's modulus E= 2.5×10^5 N/m^2
thickness of material L_o =3.0 mm
Area A= 0.50 cm^2
ΔL= 1.0 cm
The potential energy is given by
U= 1/2FΔx
therefore
now putting values we get
U= 4.1×10^{-3} J
Answer:
The formula for potential energy depends on the force acting on the two objects. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.
