Upon arrival, you measure the actual force of gravity to be 6x105 N, which is different from your calculated value in question 1. Identify 2 specific possible causes that would account for the difference in expected vs. actual values, and why they would affect the calculation.

How are series and parallel circuits simililar? both have multiple paths for electrons to travel. both require resistors in their circuits. both require a switch to complete the circuit. both have at least one path for electrons to travel.

Two conductors, a and b, are each in the shape of a tetrahedron. but of different sizes. they are charged in the following manner: 1. tetrahedron a is charged from an electrostatic generator to charge q. 2. tetrahedron a is briefly touched to tetrahedron b. 3. steps 1 and 2 are repeated until the charge on tetrahedron b reaches a maximum value. if the charge on tetrahedron b was q/4 after the first time it touched tetrahedron a. what is the final charge qbmax on tetrahedron b?

Calculate a pendulums frequency of oscillation (in hz) if the pendulum completes one cycle in 0.5s.
