Compute each part of given problem:
Problem: A person scuffing her feet on a wool rug on a dry day accumulates a net charge of -20.6 µC.
Part I: How many excess electrons does she get?
Part II: By how much does her mass increase (in kg)?
Please show me how work it out above problem.

A hypodermic syringe contains a medicine with the density of water (see figure below). The barrel of the syringe has a cross-sectional area of 2.50 x 10^-5 m2. In the absence of a force on the plunger, the pressure everywhere is 1.00 atm.
The proper length of one spaceship is three times that of another. The two spaceships are traveling in the same direction and, while both are passing overhead, determine the speed of the faster spaceship
A 0.25-kg block rests on a friction-less wedge that has an inclination of 71 degrees and acceleration to the right such that the mass remains stationary relative to the wedge. Find the acceleration
They should have opposite magnitudes. They should have equal magnitudes. Their x-components should be equal. They must be parallel (point in the same direction). They should be anti-parallel (point in opposite directions). Their y-components should b..
