A graduated cylinder contains 20.0ml of water. After a rock is placed in the cylinder, the level rises as shown below. what is t
1 answer:
The volume of the rock, given the data is 14 mL (Option A)
<h3>Data obtained from the question</h3>From the question given above, the following data were obtained:
- Volume of water = 20 mL
- Volume of water + rock = 34 mL
- Volume of rock =?
The volume of the rock can be obtained by calculating the displacement of the water when the rock was added. this can be obtained as follow:
Displacement of water = (Volume of water + rock) - (volume of water)
Displacement of water = 34 - 20
Displacement of water = 14 mL
Thus, the volume of the rock is 14 mL

Answer:
∑Fy = 0, because there is no movement, N = m*g*cos (omega)
Explanation:
We can solve this problem with the help of a free body diagram where we show the respective forces in each one of the axes, y & x. The free-body diagram and the equations are in the image attached.
If the product of mass by acceleration is zero, we must clear the normal force of the equation obtained. The acceleration is equal to zero because there is no movement on the Y-axis.
