Can someone please help

Under normal conditions, describe how increasing the temperatures effects the solubility of a typical salt

A1.5m wire carries a 2 a current when a potential difference of 52 v is applied. what is the resistance of the wire?

An air-filled capacitor is formed from two long conducting cylindrical shells that are coaxial and have radii of 26 mm and 103 mm. the electric potential of the inner conductor with respect to the outer conductor is - 700 v (k = 1/4πε 0 = 8.99 × 109 n · m2/c2) the energy stored in a 1.0-m length of this capacitor is closest to
