Hey! I'm working through the lab on Archimedes Principle and Buoyancy. I need someone to check my work, as my actual and theoretical values between question 2 and 3 are... pretty different from one another. should I be using a negative value for my buoancy? Thank you!

can you please do all of them. thank you

Answer this question.

5. An engineer is planning to use gabion retaining wall to protect a section of Kennon road from landslide. A gabion is a wire mesh container filled with rocks. The engineer must estimate the volume of the rock to be used. If the gabion wall will have a thickness of 5ft, estimate the volume of the rocks given the measured depth of the wall every 10 ft of its width based from the road level. width, ft 10 20 30 40 50 60 70 80 90 depth, ft 5 12 20 18 17 13 10 5 a.) estimate the area of the wall using multiple trapezoidal rule with n=9 b.) estimate the area of the wall using single application of Simpson's 3/8 rule c.) estimate the volume of the rocks to be used using the area in a.) and b.)

If the object weighs 10kg and the fulcrum is located 10 cm from the load, how much force (in Newtons) must you apply to raise the object? Effort Load Class 1 Lever Fulcrum

The right answer should be F_lift= 105 kip and F_thrust= 415 kip. I tried many times with acceleration in horizontal but couldn’t get these correct numbers.

write some paragraphs explaining this calculation. my be one paragraph is enough. i am doing the discussion so I need your help

Please don't use chatgpt,you will not get correct as i tried. Attempt only if you are sure ,Solve in a handwritten format. Question: An open rectangular tank is 3 m wide and 12 m long. The tank contains water to a depth of 4 m and oil (SG = 0.8) on top of the water to a depth of 2 m. Determine the magnitude of the resultant fluid force acting on the smaller end of the tank. Answer Format: Resultant Force ______ kN

You are tasked with designing the runway on an aircraft carrier. The minimum speed for the F/A-18 Hornet is 193.8 mph. The Hornet weighs 40,000 lbf and its twin engines provide a thrust of ~40,000 lbf combined, providing a max acceleration of 1g. How long must the deck be to takeoff unassisted in feet?
