<span>I believe this happens because when you rub the balloon on the carpet or fabric, the connection or contact of that jumbles up the atoms and they receive the energy which makes your hair as the question said 'stand on end' </span>

A force is applied to an ideal spring (initially in its equilibrium position) and does 1.9 JJ of work stretching it 2.2 cmcm . H

Verdich [7]

Answer:

W=16.58J

Explanation:

initial information we have

work: $W=1.9J$

stretched distance: $x=2.2cm=0.022m$

from this, we can find the value of the constant of the spring k, with the equation for work in a spring:

$W=\frac{1}{2} kx^2$

substituting known values:

$1.9J=\frac{1}{2}k(0.022)^2\\$

and clearing for k:

$k=\frac{2(1.9J)}{0.022^2} \\k=7,851.24$

and now we want to know how much work is done when we stretch the spring a distance of 6.5cm from equilibrium, so now x is:

$x=6.5cm=0.065m$

and using the same formula for work, with the value of k that we just found:

$W=\frac{1}{2} kx^2$

$W=\frac{1}{2}(7851.24)(0.065)^2\\W=16.58J$
