The potential energy, P, in a spring is represented using the formula P = kx2. Lupe uses an equivalent equation, which is solved

ella [17]

Original equation is $P=kx^{2}$

So, $kx^{2} =P$ and

$k=\frac{P}{x^{2} }$

If we compare this equation with the given options, we can easily find that this matches with the last one $k=\frac{p}{2x^{2} }$ with P = p/2.

Hence, correct option is $k=\frac{p}{2x^{2} }$ .

Solve the equation √x-6 +2=6

Dovator [93]

Answer:

x = 22

Step-by-step explanation:

$\sqrt{x-6}$ + 2 = 6 ( subtract 2 from both sides )

$\sqrt{x-6}$ = 4 ( square both sides to clear the radical )

x - 6 = 4² = 16 ( add 6 to both sides )

x = 22
