This one is just if you know i already know the answer but do you guys know? A In the last century, word spread of Zion National Park's many natural treasures, like
the Weeping Rock.

B More people traveled to Zion in order to hike, horseback ride, and go canyoneering.

C Visitors are straying off the trails to create their own, thereby damaging the vegetation.

D Visitors still use the tunnel to travel from Zion to the Grand Canyon or Bryce Canyon.

Divide 108.2 x 10^6 into 1.5 x 10 and the result will be in au (astronomical units)

Electoral current force mechanical advantage if the wheel and axle is 2 n and the output force is 20 n

Pe = 1/2k(x)^2  and .05n/m = .05x10^-9m = x 

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
