A add more mass to F3
2. mechanical advantage is 2
therefore the ratio of F/G is D i.e. 1/2
1. Tam dong the experiment in Chapter 4. Here is the situation I got. The center...
got the answers i just need the work shown to get them. here is the problem, the graph, and numbers 227- Preliminary Problem Add the following three forces geometrically, where F, - 300 F,- 400g and F, - 350 g. (Note that we are using mass as weight, since they are proportional Strictly speaking, we should change grams into Newton to represent forces) Use the paper provided to do this exercise F:- 400g 20 F1 - 300g F, = 350g...
I am in a intro engineering physics and having issues with this classwork for our lab.... the values are given in the table.thank u In this exercise, you will begin with a system that is not in equilibrium, predict the mag nitude and direction of a force necessary to place it in equilibrium. You will also use second graphical technique to reach the same conchusion. Measurements around the side of the table mark 360 degrees. We will set 0 degrees...
Can someoneplease help me with #3 - to find Etheo and Theta? I think the correct andwer is theta = 79.94 but i keep getting something else. Analysis Calculate Ethe and Oneo from the forces given in the problem (F, etc.). See the introduction for outline of the procedure. an Calculate the differences between experimental and theoretical values. Standards: Theoretical and experimental force magnitudes should agree to within 5 grams. Theoretical and experimental force directions should agree to within 2°...
I've got parts a-c and understand them. However, I do not understand the rest of the problem and how to solve for the answers in parts d and e. Any explanation would be helpful. (1 point) A mass of 4 kg stretches a spring 40 cm. The mass is acted on by an external force of F(t) = 97 cos(0.5t) N and moves in a medium that imparts a viscous force of 8 N when the speed of the mass...
Multivariable Calculus help with the magnitude of angular momentum: My questions is exercise 4 but I have attached exercise 1 and other notes that I was provided 4 Exercise 4. In any mechanics problem where the mass m is constant, the position vector F sweeps out equal areas in equal times the magnitude of the angular momentum ILI is conserved (Note: be sure to prove "if and only if") (Note: don't try to use Exercise 2 in the proof of...
3. For experiment A, use equations 1&3 to develop a general equation for the value of tension (T) based on the values of the two masses. You will need this later to answer lab question (4), so write it in now. 4. Based on the "net force" and "total mass" approach that was used to derive equations 3,4, and 5; develop the equation for acceleration of two masses (m, and m2) hanging vertically from either side of a frictionless pulley....
Attached is the lab experiment. Here are the questions I need help with: 1. What is the purpose of each of the following steps in this experiment? a. Adding solid NaCl to the reaction mixture b. Repeated washings with water, sat'd NAHCO3, and brine c. the pipet column chromatography 2. Which compound, cyclohexanol or cyclohexanone will have a higher Rf on a TLC plate? 3. What is the advantage of using sodium hypochlorite as an oxidant over CrO3 or Na2Cr2O7...
please answer all prelab questions, 1-4. This is the prelab manual, just in case you need background information to answer the questions. The prelab questions are in the 3rd photo. this where we put in the answers, just to give you an idea. Lab Manual Lab 9: Simple Harmonic Oscillation Before the lab, read the theory in Sections 1-3 and answer questions on Pre-lab Submit your Pre-lab at the beginning of the lab. During the lab, read Section 4 and...
I need help with my very last assignment of this term PLEASE!!, and here are the instructions: After reading Chapter Two, “Keys to Successful IT Governance,” from Roger Kroft and Guy Scalzi’s book entitled, IT Governance in Hospitals and Health Systems, please refer to the following assignment instructions below. This chapter consists of interviews with executives identifying mistakes that are made when governing healthcare information technology (IT). The chapter is broken down into subheadings listing areas of importance to understand...
I need help to write a nice introduction for experiment 6 please ( no hands write ) typing Thank you HEAT TREATMENT OF STEELS EXPERIMENT 6 EXPERIMENT 6 HEAT TREATMENT OF STEELS THEORY The Effect of Cooling Rate One of the most convenient methods for controlling the properties of a given steel, i.e., a steel whose composition is already fixed, consists of austenizing the steel and ten cooling to room temperature at some predetermined rate. A variation of cooling rates...
