As an intern at an engineering firm, you are asked to measure the moment of inertia of a large wheel for rotation about an axis perpendicular to the wheel at its center. You measure the diameter of the wheel to be 0.840 m. Then you mount the wheel on frictionless bearings on a horizontal frictionless axle at the center of the wheel. You wrap a light rope around the wheel and hang an 8.20 kg block of wood from the free end of the rope, as in (Figure 1). You release the system from rest and find that the block descends 12.0 m in 4.00 s. Part A What is the moment of inertia of the wheel for this axis? Express your answer with the appropriate units.

How was 20degrees gotten ?

A plan represents an area of 93750 sq.m and measures 6 cm x 6.25 cm. Find out scale of map (plan), and construct a scale which can measure up to 1 m.??? please answer it fast

Please do not give solution in image format thanku If you want to do your scale model presentation in such a way that BOTH the size AND distance scaled are correct, how far apart would your squishy stress ball Moon and your answer to the previous question need to be? HINT: Multiply the diameter of the scale model Earth that you chose in the previous question by the number of Earth diameters that would fit between the Earth and the Moon.   Answer choices:   A- You'll need to put one against one wall and hold the other one across the room 240 inches or 20 feet apart   B- You will need a volunteer from the audience so you can hold them 72 inches or 9 feet apart   C- You could hold them both in front of you at 16 inches or about 1.3 feet apart   D- You'll need to tell the kids to use their powers of imagination because the separation would put one of them in the parking lot outside the science center 3600 inches or 300 feet away
