5. If you were asked to give an example of kinetic and potential energy, which of the following would be the best choice.
A. An example of kinetic energy is Dwayne Wade scoring a layup at a Heat game while an
archer pulling the string all the way back on a bow and arrow is an example of potential
energy
B. An example of kinetic energy is a roller coaster at its fastest speed but the roller coaster
at its slowest speed is an example of potential energy.
C. An example of kinetic energy is a ball rolling in the street and a baby crawling is an
example of potential energy.
D. An example of kinetic energy is airplane flying in the sky while running water is an
example of potential energy.

The reflection of the candle in the concave mirror formed an upside-down virtual image that is smaller than the candle.in other words. the answer is the third option, c

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
