SITUATION 1
Direct evidence of Newton's universal law of gravitation was provided from a renowned experiment by Henry
Cavendish (1731-1810). In the experiment, masses of objects (treated as samples) were determined by
weighing, and the measured force of attraction was used to calculate the density of the earth. The values of
the earth's density (in g/cm³), in time order by row, are:

- 2. A platform edge x(1) section of a uniform chain of length 8 ft is loosely wound around a peg at the edge of a high horizontal platform, and the remaining part of the chain hangs still on the edge of the platform. The length of the extended chain is 3 ft, the chain weighs 2 Ib/ft, and the positive direction is downwards. Starting at t = 0 seconds, the weight of the outstretched part causes the chain on the table to slip smoothly and fall to the floor. If x(t) represents the length of the chain protruding into the table at time t = 0, then v = dx/dt is the velocity. When all resistive forces are neglected, it can be shown that the mathematical model relating v to x is: dv XV-+ v2 = 32x dxarrow_forwardWest Gorham High School is to be located at the population center of gravity of three communities: Westbrook, population 17,500, Scarborough, population 23,000, and Gorham, population 33,500.

- Due to climate change, from 2011 onward, every year the island is hit by hurricanes of increasing force that destroy capital. As a result, the depreciation rate doubles. What will be the new long-run (steady state) value for income per worker (Y/L)? Pick the closest value. Also label the new steady-state GDP as point C in the diagram.

Suppose that the productivity parameter is A=90, the depreciation rate is d=1/10, the savings (investment) rate is s=0.10, and the labor force is equal to 2 million (and constant over time). Suppose in year 2010 the economy is in a steady state. Compute the 2010 values for overall capital (K) and income per worker (Y/L). Pick the closest values. The stock of capital is between 6 and 7 million. Income per worker is between 2.5 and 3.3. O None of the other options The stock of capital is between 62 and 66 trillion.
