Dmitry_Shevchenko [17]

Answer:

Dipole is two equal but opposite charges in one. As like charges repels and unlike charges attracts each other. If dipole are in electric field region, it positive side will be attracted to the negative field and vis-versa. This will result to different movement or stationary based on the orientation of the field. If the interaction between other dipole is considered this effect may be obstructed

love history [14]

Answer:

It lies in in the visible region.

Frequency: is 7.407 × 10^-14 Hz

${ \bf{V = f \lambda}} \\ { \tt{3.0 \times {10}^{8} = f \times (405 \times {10}^{ - 9}) }} \\ { \tt{f = 7.407 \times {10}^{14} \: hertz}}$

Explanation:

V is speed of light.

f is frequency

lambda is the wavelength

rusak2 [61]

Answer:

235/92U+10n→144/54Xe+90/38Sr+2/10n

Explanation:

The nuclear reaction for the neutron-induced fission of u−235 to form xe−144 and sr−90 is represented by;

235/92U+10n→144/54Xe+90/38Sr+2/10n
