A 0.10g honeybee acquires a charge of 25pCwhile flying. The electric field near the surface of the earth is typically 100N/C , directed downward.
What is the ratio of the electric force on the bee to the bee's weight?
A 54 N crate is suspended from the left end of a plank. The plank weighs 21N, but it is not uniform, so its center of gravity does not lie halfway between the two ends. The system is balanced by a support that is 0.3m from the left end of the plan..
A 2.00-g charged particle is released from rest in a region that has a uniform electric field = (160 N/C) . After traveling a distance of 0.520 m in this region, the particle has a kinetic energy 0.080 J. Determine the charge of the particle.
A loudspeaker at a rock concert generates 10-2 W/m2 at 18 m at a frequency of 1 kHz. Suppose that speaker spreads its energy uniformly in all directions. What is the intensity level at 18.00m.
A swimming pool has dimensions 32 m 11 m and a flat bottom. When the pool is filled to a depth of 2.10m with fresh water, what is the force caused by the water on the end that is 11m.

Two stationary positive point charges, charge 1 of magnitude 3.25 nC and charge 2 of magnitude 1.9nC, are separated by the distance of 60 cm. An electron is released from rest at the point midway between the two charges, and it moves along the lin..
The bullet passes right through and emerges on the other side with a speed of 100 m/s, and the saxophone is given a speed of 4.8 m/s.
It compresses the spring, and then is pushed back in the opposite direction by the spring, eventually losing contact with the spring.
Two metal spheres, each weighing 24-kg are placed 0.05 m apart. Compute the magnitude of the gravitational force the two spheres exert on each other.
