<h2>Orbital Period:</h2>
- To answer this problem, we must employ the gravitational notion and equation. We already know that gravitational force provides the required centripetal force for orbital motion. As a result of matching gravitational and centripetal forces, we may get the equation for orbital time period.
<h2>Answer and Explanation:</h2><h3>Given:</h3>
- Mass of Sun (M) = 1.99 * 10^30 Kg
- Orbital radius of the Neptune
- (R) = 30 A.U. = 30 * (1.496 * 10^11) m
- R = 44.88 * 10^11 m
Now we know that the time period is given by
T^2 = 4π^2R^3/GM
T^2 = 4π^2*(44.88*10^11)^3/6.67*10^-11*(1.99*10^30)
T = 5.19 * 10^9 s
Now we know that
1 year = 3.154 * 10^7 s
Therefore, T = 5.19*10^9 s/ 3.154 * 10^7 (s/year)
T = 164.4 year
Crop diseases

government encouragement to let land remain uncultivated
Answer: tax cuts, increases in military spending, and recessions
The Great Depression of America!
It all began with the economic recession in August 1929, but everything got worst on October 24th, 1929: The Black Thursday, or the Crash of Wall Street, Which affected all the world. Then a year later, Banks began to fail. The economy was dead, not only for the united states, but for the whole world. It stayed like that till World war 2 in 1939.
Hope this Helps! :)
