What is the overall charge of 1.5 x 10^10 electrons?

The force between to objects of charge + Q and - 2 Q, respectively, is measured as - 2F. If the charge on the first object is doubled and the distance between the objects is doubled, what will the force between the objects become?

What is the difference between a foliated and a non-foliated metamorphic rock?

A car of mass m1 stopped at a traffic light is rear-ended by a car with mass m2. The cars become entangled. The second car was moving at a velocity of v2 before the collision. What is the kinetic energy of the system after the collision?

Use the equation d = m/v [stack fraction), where d = density, m = mass, and v = volume. If a rock as a density of 9 g/cm and a volume of 6 cm?, what is its mass?

What two equations can be used to determine the speed of a wave
