Asound’s pitch is measured in decibels.

True, a sounds pitch is measured in decibels

Decibels are a unit that is used to measure the intensity of sound of sound, so yes this would be true.

To think about: A chainsaw produces around 80-110 decibels as well as lawn mowers, the Human voice is normally about 20-50 decibels. Car horns are about 100-110 decibels, too.

(So the next time someone's blowing their horn at 3:00 AM in the morning, you can feel free to finally tackle that crab grass without any additional annoyance to the neighbors)

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
