Answer:
Attract
Explanation:
According to the properties of charge, the bodies having unlike charges attract each other and the bodies having like charges repel each other.
As the toy is initially electrically neutral, so as it is divided into two pieces, then according to the conservation of charge, the one piece having positive charge and the other piece having negative charge. As they are unlike charges so they attract each other.
The humoral response is mediated by B lymphocytes<span>, which release antibodies specific to the infectious agent. The cell-mediated response involves the binding of cytotoxic </span>T lymphocytes<span> to foreign or infected cells, followed by the lysis of these cells.</span>
By definition, the refractive index is
n = c/v
where c = 3 x 10⁸ m/s, the speed of light in vacuum
v = the speed of light in the medium (the liquid).
The frequency of the light source is
f = (3 x 10⁸ m/s)/(495 x 10⁻⁹ m) = 6.0606 x 10¹⁴ Hz
Because the wavelength in the liquid is 434 nm = 434 x 10⁻⁹ m,
v = (6.0606 x 10¹⁴ 1/s)*(434 x 10⁻⁹ m) = 2.6303 x 10⁸ m/s
The refractive index is (3 x 10⁸)/(2.6303 x 10⁸) = 1.1406
