Determine the stress in the cable at B, g

Problem 7 Marooned You are stranded on a boat with no way to paddle to the shore (and no water current to move the boat). You have mass 2m and the boat also has mass 2m. In addition, you brought 2 weights from the physics lab that each have mass m. Since you have been hitting the gym with Juan, you can throw the weights with an impressive speed of vo. (a) If you throw both weights off the back of the boat simultaneously, what will the speed of the boat (and you) be? (b) Suppose instead you throw each weight off the back of the boat individually. What will the speed of the boat be in this case? (Be careful when considering how fast the second weight is thrown with respect to the water). (c) If you were trying to get to shore as fast as possible, which method should you choose? Should you throw the weights towards shore or away from shore?

After years of asking, you finally were allowed to go on a joy ride in your uncle’s 1956 Mercedes-Benz 300 SL. A notable feature of this vehicle is the gullwing door design that opens from a hinge at the top of the car. Unfortunately, you are having so much fun driving the car that you end up submerged in a fresh water lake. You sink to the bottom of the lake, which has a depth of 10 m. For the sake of simplicity, you can model the door as a 1 m × 1 m square plate, inclined at 45° relative to the floor of the lake. Neglect the weight of the door and friction in the hinge. How much force will be required to open the door, assuming you push from its geometric center?

Learning Goal: A centroid is an object's geometric center. For an object of uniform composition, its centroid is also its center of mass. Often the centroid of a complex composite body is found by, first, cutting the body into regular shaped segments, and then by calculating the weighted average of the segments' centroids.An object is made from a uniform piece of sheet metal. The object has dimensions of a = 1.45 ft, where a is the diameter of the semi-circle, b = 3.24 ft, and c = 2.10 ft. A hole with diameter d = 0.500 ft is centered at (1.13, 0.725).

Parts a and b were answered in a previous question, part c was unanswered this is the entire question :)

I only need help with answering part F please!

An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J).  It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).

Subject:Thermodynamics IPlease with complete solution , so that i can learn too

I need help with Parts A and C on this question!

1. The development of thermodynamics since the 17th century, which was pioneered by the invention of the steam engine in England, and was followed by thermodynamic scientists such as Willian Rankine, Rudolph Clausius, and Lord Kelvin in the 19th century. explain what the findings or theories of the 3 inventors are! Please answer fast max 25-30.minutes thank u
