Styrofoam is a polymer containing carbon and hydrogen. Assume the formula is C8H8. How many molecules are in a 0.2 g styrofoam peanut? How many protons and electrons are in this peanut if it carries no excess charges? How many coulombs of positive and negative charge does this represent? If the...

Homework Statement A Van de Graaff generator is charged so that the electric field exerted at the top surface is 2.0× 10^6 N/C directed upwards. Find the a) the electric force exerted on a styrofoam peanut (q= 0.025μC) released at its surface, b) the gravitational force on the peanut, c) its...

Consider a segment of a molecule of DNA that is a coil with an overall length of 1.6 μm. If the end of the molecule become singly ionized (one end loosing a single electron and the other end gaining a single electron) the helical molecule acts like a spring and compresses 1.10% of its original...
