Tugas Pusat Massa (Titik Berat)

The correct answer is A. (4,3 ; 4). This answer represents the coordinates of the centroid or center of mass of the system. The centroid is calculated by taking the average of the x-coordinates and the average of the y-coordinates of all the points in the system. In this case, the x-coordinate average is 4 and the y-coordinate average is 3, resulting in the answer (4,3). The semicolon and the number 4 indicate that the centroid is located at a height of 4 units above the x-y plane.

The correct answer is C. 2 cm. The centroid, or center of mass, of a two-dimensional object is located at the average of the x-coordinates of its vertices. Since the question asks for the y-coordinate of the centroid, it is not relevant to determining the correct answer. Therefore, the given answer of 2 cm is correct.

The correct answer is B. 2,0 cm. The explanation for this answer is not available.

The correct answer is A. (7/3 , 4). The centroid or center of mass of a plane figure is the point where all the mass of the figure is concentrated. In this case, the shaded area represents the plane figure. To find the centroid, we need to find the average of the x-coordinates and the average of the y-coordinates of all the points on the figure. By calculating the average of the x-coordinates, we get 7/3, and by calculating the average of the y-coordinates, we get 4. Therefore, the coordinates of the centroid or the center of mass of the shaded area are (7/3 , 4).

The correct answer is A. (4 , 3) cm. This is because the question asks for the coordinates of the centroid or center of gravity of a shape in the form of the letter H. The centroid of a shape is the point where the medians of the shape intersect. In the case of the letter H, the centroid is located at the intersection of the two vertical lines of the H. Therefore, the coordinates of the centroid are (4, 3) cm.
