A rectangular swimming pool is 10.0 m wide and 15.0 m long. The water depth varies over the length of the pool in three 5.0 m zones. The zone under the diving board is 3.0 m deep. The shallow zone at the other end is 1.0 m deep. The zone in the middle has a sloping bottom changing from 3.0 m to 1.0 m deep

A. What is the volume of the pool in cubic meters? B. What is the volume of the pool in liters?C. The density water at pool temperature is 1.0 g / cm³. What is the mass, in kilograms, of the entire volume of water in the pool? D. If a swimmer is allotted 5.0 m² of surface swimming space, how many swimmers may be in the pool at one time?

Sorry i don’t know what to do

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

Mass and velocity are the 2 factors used to calculate kinetic energy. the equation for kinetic energy is (1/2)mv^2. hope this !
