How does fabric softener help prevent static electricity?

Physics
1 answer:
algol132 years ago
3 0

Answer:

Dryer sheets stop static cling by absorbing static electricity formed by different fabrics during your dryer cycle. The fabric softeners that coat dryer sheets are positively charged ions to balance the electrons and ions that cause static cling, leaving you with soft clothes without the static.

Two children stretch a jump rope between them and send wave pulses back and forth on it. The rope is 2.6 m long, its mass is 0.5
Irina-Kira [14]

Answer:

15.13 m/s

Explanation:

The wave speed of the stretched rope can be calculated using the following formula

v = \sqrt{\frac{F_T}{\mu}}

where F_T = 44N is the tension on the rope and \mu = m/L = 0.5 / 2.6 = 0.1923 kg/m is the density of the rope per unit length

v = \sqrt{\frac{44}{0.1923}} = \sqrt{228.8} = 15.13 m/s

PLEASE HELP ME W 86,87,88​
denis-greek [22]

1) Right answer: 9.8m/s^{2}

Gravity is a physical force with which the Earth exerts on all bodies towards its center due to the fact its mass is greater than the bodies on its surface.

Nevertheless, it is important to note that this value is not the same in all the points of the planet, that is why an average value is used, which is 9.8m/s^{2}.

2) Right answer: 8m/s

The Average Velocity Formula is:

V_{average}=\frac{V_{i}+V_{f}}{2}

Where V_{i} is the Initial Velocity and V_{f} is the Final Velocity.

Knowing this, let's apply the formula:

V_{average}=\frac{0m/s+16m/s}{2}

V_{average}=8m/s

3) Right answer: 19m/s

V_{average}=\frac{10m/s+28m/s}{2}

V_{average}=19m/s

4)  Right answer: 47 mph

V_{average}=\frac{19mph+75mph}{2}

V_{average}=47mph
