1.A pendulum performs 60 complete oscillations in 2 minutes. Find the period and frequency of the pendulum.

2.The bee's wings, when it flies, oscillate at a frequency of 225 Hz. Calculate how many times its wings go up and down in 1 s as well as the oscillation period.

​

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.
