Honey bees can acquire a small net charge on the order of 1 pc as they fly through the air and interact with plants. estimate the magnetic force on a honey bee due to earth's magnetic field as the bee flies near the ground from east to west. average speed of a bee is 15 miles/hour.
hint: model the honey bee as a moving, charged point particle. the direction the bee flies is significant.
feedback: model the charged honey bee as a point particle.

Explanation:

The force exerted on a charged particle due to a magnetic field is given by:

where

q is the charge of the particle

v is the velocity of the particle

B is the magnetic field strength

is the angle between the directions of B and v

In this problem we have:

is the charge of one honey bee

is the velocity of the bee

is the average strength of the Earth's magnetic field

, because the bee flies east to west while the Earth's magnetic field is south to north

Substituting into the equation, we find:

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
