Because all blocks weigh the same, their masses must also be equal. Density is defined as mass per unit volume, so we know the densities of the red and blue blocks are different because their volumes are not the same. Since the volume of a blue block is one-half the volume of a red block, the density of a blue block is the density of a red block.

a. half
b. equal to

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
