Well it is due to the fact that when you
submerge
the wooden block into the cylinder. The displacement of water from the initial-measurement (before the block was submerge) to finial-measurement will be the volume of wooden block.
Note: In cases of floating objects. You can always add a sinker to it to submerge the object.
But
you will need to take into account the volume of the sinker and minus off the added volume of sinker.
Answer:
Student A is correct
Explanation:
Colored objects look the way they do because of reflected light. When sunlight is shined on a green leaf, the violet, red and orange wavelengths are absorbed. The reflected wavelengths appear green. In each case we are seeing the complementary colors to the ones absorbed.
Answer:
a) Magnitude = 1.03 m/s², Direction: south
b)
Explanation:
a) The magnitude and direction of the acceleration can be calculated using the following equation:
(1)
Where:
: is the final speed = 9.40 m/s
: is the initial speed = 13.0 m/s
t: is the time = 3.50 s
Solving equation (1) for a, we have:
Hence, the magnitude of the acceleration is 1.03 m/s² and the direction of the bird's acceleration is the opposite of the initial velocity direction, which means that the bird is decelerating.
b) The final velocity of the bird can be found using the same equation 1:
Therefore, the bird’s velocity after an additional 1.20 s has elapsed is 8.16 m/s.
I hope it helps you!
