A hungry bat finds the mother lode of flying insects between the headlights of two bicycles cruising towards each other through Busse Woods Forest Preserve. The bikes are initially 200 meters apart and one has a speed of 8 m/s while the other has a speed of 10 m/s. The bat flies at a constant speed of 20 m/s, but flies back and forth between the two bicycles continuously. Determine the total distance the bat has traveled when the bicycles meet.

Answer: a charge of -1.0  × 10⁻⁴ c must be placed  at x = 26 m.the sign of the charge will be the same sign as the  -4.0  µc charge.======electricstatic force between two point charges  is given by    where k is coulomb's constant,  8.99×10⁹  n·m²/c², q₁ and q₂ are the point charges, and r is the distance between the two point charges.assign positive to q₁let q₁ =  6.0 µc, q₂ = -4.0  µc, q₀ represent the charge at the origin, and q₃ represent this new charge to place.the charge at the origin q₀ would experience the following force f₀₁ from q₁, with r = 6.0 m (note that 1  µc = 10⁻⁶ c)    the force from q₂    the force from q₃    the net force on the origin charge, q₀, has to be zero for no electrostatic forcehaving an equation where k and q₀ can be divided out of the equation will allow us to solve for q₃    isolating:     a charge of -1.0  × 10⁻⁴ c must be placed  at x = 26 m.the sign of the charge will be the same as the  -4.0  µc charge

The answer is a your welcome

If you are a plato user the answer would be "a decrease in the overall volume of gases" i just completed the test and this was the answer. hope it ! (:

The sounds will have a high pitch because the metal is vibrating quickly
