Arock climber is about to haul up 100 n (about 22.5 lb) of equipment that has been hanging beneath her on 40 m of rope weighing 0.8 n/m. how much work will it take to lift all this? ? 8) a vertical cylindrical tank measures 30 ft high and 20 ft in diameter. it is full of kerosene weighing 51.2 lb/ft. how much work (ft-lb) does it take to pump the kerosene to the level of the top of the tank (i. e to pump all the kerosene out the top of the tank).

Nps pollution is caused by rainfall or snowmelt moving over and through the ground. nonpoint source pollution can include: excess fertilizers, herbicides and insecticides from agricultural lands and residential areas. oil, grease and toxic chemicals from urban runoff and energy production

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
