A drop of water dripping from the faucet in your kitchen is electrically neutral. A charged plastic hair comb can attract the drips and drops by the process of .

Polarizatión

Explanation:

Polarization is that property of waves that particular to transverse waves. Ir specifies the geometrical orientation of the oscillations. In transverse waves, the direction of the oscillation is often at perpendicular with respect to the direction of motion of the wave itself.

Again, it can be called the property of electromagnetic radiations to which the direction and magnitude of the vibrating electric field are related in a particular way.

the answer is b ) square root of 5

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.
