To determine the location of the center of mass (or center of gravity) of a car, the car is drivenover a scale on a horizontal floor. when the front wheels are over the scale, the weight recordedby the scale is 5800 n, and when the rear wheels are over the scale, the scale reads 6500 n. thedistance between the front and rear wheels is measured to be 3.20 m. how far behind the frontwheels is the center of mass located? a) 1.59 m b) 1.50 m c) 1.72 m d) 1.69 m e) 0.845 m

Acylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32×10^5 pa. the gas is initially at a temperature of 300 k. an electric heater adds 43200 j of energy into the gas while the piston moves in such a way that the pressure remains constant. cp=20.79 j k^−1 mol^−1 for a monatomic ideal gas, and that the number of gas molecules is equal to avogadro's number (6.022×10^23) times the number of moles of the gas. (a) what is the temperature of the gas after the energy is added? (b) what is the change in volume of the gas? (c) how much work is done by the gas during this process?

Apatient has a history of poor nutrition. he has skin rashes, bleeding gums, and a cut that hasn’t healed in a long time. what vitamin deficiency most likely caused this symptom?

Assume you measured the mass of the cart to be (500 ± 1) g and the mass of the additional mass you put on the cart to be (500 ± 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass
