Name the law that states that the sum of allelic frequencies in a population remains constant. What are the five factors that influence these values?

State and explain any three factors affecting allele frequency in populations.

Let the resistance of an electrical component remains constant while the potential difference across the two ends of the component decreases to half of its former value. What change will occur in the current through it?

A sitar wire is replaced by another wire of same length and material but of three times the earlier radius.If the tension in the wire remains the same,by what factor will the frequency change?

It is known that density rho of air decreases with height y (in metres) as : rho = rho_(0) e^(-y//y_0) where rho_0 = 1.25 kg m^-3 is the density at sea level and y_0 is a constant. This density variation is called the law of atmospheres. Obtain this law assuming the temperature of atomoshpere remains constant (isothermal conditions). Also assume that the value of g remains constant.

In Coulomb’s law, on what factors the value of electrostatic force Constant ‘K’ depends ?
