C-lab Answer the following questions. You may upload a handwritten file if you like, as long as it is legible. Part A: Figure numbers refer to figures in the lab procedures. Do the calculations in the units given. 1. Very briefly explain how a photogate works. 2. How far would you go if you traveled at a speed of 30 miles per hour for 3 hours? 3. What acceleration would be needed to travel the same distance in the same time as in question 2 when starting from rest? What would be your final speed? 4. Refer to Figure 3. Given a track length of 90 cm and a height difference of 18 cm, what is sin 0 5. Draw the force diagram for an object on an inclined plane (see Figure 2 in the lab manual). Attach the diagram in question 2 below. What would be the acceleration given the inclination from question 4 and g = 9.8 m/s? Part B: Attach the free body diagram from question 5 above.

The compound cyclohexanol, C6H120, is a good fuel. It is a liquid at ordinary temperatures. When the liquid is burned, the reaction involved is 2 C6H120(t) + 17 02(g)→12 CO2(g) + 12 H20(g) The standard enthalpy of formation of liquid cyclohexanol at 25 °C is -348.2 kJ mol-1; other relevant enthalpy of formatton values in kJ mol1 are: C6H120(g) = -286.2 ; CO2(g) = -393.5 ; H20(g) = -241.8 (a) Calculate the enthalpy change in the burning of 3.000 mol liquid cyclohexanol to form gaseous products at 25°C. State explicitly whether the reaction is endothermic or exothermic. = oHV (b) Would more or less heat be evolved if gaseous cyclohexanol were burned…

Which of the following scenarios is (are) incidence(s) of human mistake? Multiple answers Group of answer choices Blanche, when measuring out their flour, accidently drops it on the floor. They don’t have any extra so they decide to pick it up and use the now contaminated flour in the experiment. Feng acquires their ingredients to make their cake but forgets to add the granulated sugar. They don’t notice until it is too late to fix. When taking readings of the cake volume, CJ takes a measurement and then writes down the time. There are a few seconds between CJ's time of reading and their ability to look at the clock. Lisa looks into the oven as their cake is baking, in order to record the volume of their cake, Lisa will need to estimate the reading based off the graduations on the beaker.

80. Comment on the accuracy and precision of the data collected about these basketball free-throw shooters. a. 99 of 100 shots are made. b. 99 of 100 shots hit the front of the rim and bounce off. c. 33 of 100 shots are made; the rest miss.

Step 2: Identify the dimensions of the quantities involved The second step is to identify the dimensions of the quantities involved in the problem. For example, if the problem involves distance, time, and velocity, the dimensions of these quantities would be length, time, and length/time, respectively. Step 3: Check if the units cancel out The third step is to check if the units cancel out. To do this, multiply the quantities together and check if the units cancel out, leaving only the desired unit. For example, if you are trying to find the velocity of an object and you know its distance and time, you can multiply distance by time to get velocity. If the units cancel out, you have a physically meaningful result. Step 4: Check if the result makes sense, to do this compare the units of the result with what you would expect based on the Robles statement.   Using the step hints above, answer the question. You do not have to solve. Just imagine that you're teaching a friend how…
