Question

Please I need help!

Problem #2: 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 tobe 500 1) gas well. Since the scale you are using in the lab can not 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 deviation of the cart and the mass? (HINTS: Which propagation of error formula from the Appendix C should you be using? Can you intuitively understand what the correct formula means, to the point that you won't need a calculator to get the right answer? ) X 9 or mcart weight-1000.0+2 Problem #3: Assume you have measured the mass of the cart and the fan which moves the cart to be (1.00 ± 0.02) kg and the acceleration of the cart to be (0.200 ± 0.004) m/s. What is the force and the standard deviation of the force which acts on the cartfan? The relationship between the applied force, acceleration and the mass of an object in 1D is F ma. (HINTS: Which propagation of error formula from the Appendix C should you be using? Can you intuitively understand what the correct formula means (pay attention to the simplicity of the propagation of the relative error and its similarity to Problem #2), to the point that you won't need a calculator to get the right answer?) F= 0.200 ± 0.0081 X N or F-0.20+0.008
