If you slide down a rope, it’s possible to create enough thermal energy to burn your hands or your legs where they grip the rope. Suppose a 40 kg child slides down a rope at a playground, descending 2.0 m at a constant speed. How much thermal energy is created as she slides down the rope?

Expert Solution

m = 40 kg

h=2m

Thermal energy created = loss in potential energy
                                                  = m*g*h
                                                  = 40*9.8*2
                                                   = 784 J

Answer: 784 J

Your task is this: conduct one of the two possible tests on the data in slide 14 (regression or correlation). Refer to the previous slides in doing the exercise. Be sure to provide a write up (narrative), which explains both the statistical significance (slide 8) and the practical significance (slide 11). A sentence for each kind of significance is sufficient. Perform the appropriate test and provide a narrative write up for the Depression and Anxiety analysis. Remember, state the statistical...

Part A) Charcoal is primarily carbon. What mass of CO2 is produced if you burn enough carbon (in the form of charcoal) to produce 5.40×102kJ of heat? The balanced chemical equation is as follows: C(s)+O2(g)→CO2(g),ΔH∘rxn=−393.5kJ PartB) What mass of natural gas (CH4) must you burn to emit 260 kJ of heat? CH4(g)+2O2(g)→CO2(g)+2H2O(g)ΔH∘rxn=−802.3kJ Express the mass in grams to three significant figures. Part C) Ammonia reacts with oxygen according to the equation: 4NH3(g)+5O2(g)→4NO(g)+6H2O(g)ΔHrxn=−906kJ Calculate the heat (in kJ) associated with the...

For this assignment, you will create three 5-slide presentations for your local Planned Parenthood. The first presentation is for a monthly information session on puberty and development. They have asked you to come in as a health professional and provide a guest lecturer on the topic of male and female development. The second presentation is for women who are in their first trimester and their partners. They have asked you to explain prenatal development, parturition, and lactation. The final presentation...

1. You slide an object across a horizontal surface, that object will eventually slow down and stop. What’s causing this and why? 2. Name two instances in your daily life where “conservation of energy” plays a role. 3. In a very general sense, if one object hits another that is stationary, how does the collision’s type (elastic vs. inelastic) affect the energy of the objects? 4. When opening a door, it is easier to do so by pushing on the...
