A 10.-newton force is required to hold a stretched spring 0.20 meter from its rest position. What is the potential energy stored
tester [92]
Data: 
Ep = ? (Joule)
if: F = k.x → F  = 10 N
x (displacement) = 0.20 m

Formula:
Ep =  \frac{F*x}{2}

Solving:
Ep = \frac{F*x}{2}
Ep =  \frac{10*0.20}{2}
Ep =  \frac{2}{2}
\boxed{\boxed{Ep = 1\:Joule}}\end{array}}\qquad\quad\checkmark

aleksley [76]

Answer:

The self and world construct

Explanation:

in physics

Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the relationship between voltage, current and resistance.

Self psychology views resistances as protecting a vulnerable self. Resistances are seen as efforts to maintain levels of organization that patients have achieved within the context of their traumatic life situation.
