Mexico’s war of independence from Spain in 1821 resulted in a political system that that was dominated by military dictators
<u>Explanation:</u>
After freedom, Mexican governmental was dominated by military dictators. The administration changed hands multiple times in the following 55 years (1821–76).
The armed forces are influenced but did not rule directly which excludes personalist dictatorships, party dictatorships, and civilian governments. The Spanish endeavors to reconquer Mexico included scenes of war among Spain and the new country.
The assignment mostly covers two periods: from 1821 to 1825 in Mexico's waters, and a second time of two phases, including a Mexican intend to take the Spanish-held Island. Despite the fact that Spain never recaptured control of the nation, it harmed the juvenile economy.
Answer:
1254.16 miles per hour
Explanation:
First, we need to calculate the circumference at 30° latitude
Circumference =2πR
Where R = Radius = 3990.5 miles
Circumference =2 * 22/7 * 3990.5 = 25083.143 miles
This is the distance traveled in one revolution
1 rev (according to the question) = 20 hours
Using dimentional analysis,
Linear Speed = Radius (25083.143) / Rev time (20)
Linear Speed = 25083.143 / 20
Linear Speed = 1254.16 miles per hour
An object moving in a circle is accelerating, even if it moves with a constant speed because the velocity changes.
<u>Explanation:</u>
The direction of an object changes constantly during its movement in circle at a constant speed. As the direction changes it results in changing the velocity of that object. This happens since velocity has direction and magnitude.as it is vector quantity.
An object will have acceleration only if a resultant force is acting on that body. When an object is moving in a circle, this resultant force is the centripetal force that is acting towards the center of the circle.
