Answer:

The net work done by friction is 127.42 J.

Explanation:

Given that,

Radius = 1.04 m

Coefficient of friction = 0.25

Weight = 78.0 N

We need to calculate the work done

The work done is the product of force and displacement.

work\ done = kF\cdot d

work\ done =k\times W\times 2\pi r

Here, F = mg = W(weight)

work\ done = 0.25\times78.0\times2\pi\times1.04

work\ done = 127.42\ J

Hence, The net work done by friction is 127.42 J.

What was the result of the Mexican army's victory over the Texan garrison at the Alamo?
sasho [114]

The result of the Mexican victory was that fallen defenders became heroes to the cause of Texan independence.<span> The Battle of the Alamo took place between February 23 and March 6, 1836 and became the central episode of the Texas Revolution . After this thirteen-day battle, the Mexican troops of General President Antonio Lopez de Santa Anna began an attack on San Antonio de Bexar, the current San Antonio in Texas. The Battle of the Alamo fought the army of Mexico against a group of Texan rebels, mostly American settlers. More than four thousand men from Santa Ana stood in front of the Alamo Fort , the last stronghold of the rebels, which barely reached 187. The Alamo was not a fortress prepared to withstand a siege. It is believed that all the rebels of the Alamo died in the siege, but Santa Anna came to lose up to about 900 men during the days that lasted the fight. However, the worst result for Santa Ana was precisely the resistance that the Texan rebels had in the Alamo, which fostered the fighting spirit of the Texans. A few days later, on March 14, 1836, Texas became independent from Mexico and a month later, Santa Ana was imprisoned.</span>
