-
A.
33 to 35 mm
-
B.
23 to 25 mm
-
C.
5 to 10 mm
-
D.
1 mm
Correct Answer:
A. 33 to 35 mm
Explanation:
The Second Battle of Panipat took place on November 5, 1556. It was a pivotal conflict between the expanding Mughal Empire, led by the young Emperor Akbar and his regent Bairam Khan, and the forces of Hemu (Samrat Hem Chandra Vikramaditya), the Hindu king ruling North India from Delhi. The battle resulted in a decisive Mughal victory after a chance arrow struck Hemu in the eye, causing his army to fall into disarray. This triumph effectively ended the Afghan challenge to the Mughal throne and solidified Akbar's rule over Northern India.
In the Vicat apparatus test, a cement paste is considered to have normal consistency when the plunger penetrates to a depth of 33 to 35 mm from the top of the mold (which corresponds to 5 to 7 mm from the bottom). This specific state identifies the precise amount of water needed to create a standard paste for further testing of setting times and soundness. Based on the options provided in the table, 33 to 35 mm is the standard measurement for penetration from the top of the Vicat mold to define normal consistency.
