Answer:
the kinetic energy decreases
Explanation:
When a liquid is cooled, the kinetic energy of the particles decreases. The force of attraction between the particles decreases, the space between the particles decreases, and the matter changes its state to solid.
D, making observations. If you make observations, you obtain information through the senses.
Labels that belong in regions X, Y, Z;
B) X: Back of hand, for force
Y: Thumb, for velocity
Z: Palm of hand, for force
We have that with v_1 =v this goes to show that the velocity of the bigger block after the collision takes place is v
From the question we are told
Suppose the blocks collide elastically. picking the positive direction to the right, what is the velocity of the bigger block after the collision takes place?
Generally the equation for Momentum is mathematically given as
P=mv
Therefore
Hence
Therefore
Hence
Now
with v_1 =v this goes to show that the velocity of the bigger block after the collision takes place is v

In physics, Hooke's law is written in equation as:
F = kx
It states that the force F exerted on the spring is directly proportional to the displacement x by a constant called spring constant k.
In the laboratory, this is done in an experiment through the apparatus shown in the attached figure. The object experimented here is the spring, and you are to find the spring constant. A known mass of object is attached below the spring. That object carries a force in the form of gravitational pull in terms of weight. When the spring stretches, the displacement is measured with the use of the ruler.
There are a number of sources of error for this experiment. First, the reading from the ruler by the reader may be inaccurate. That's why digital balances are much more reliable because it minimizes human error. Reading the measurement on the ruler is subjective especially when you don't read it on eye level. Second, the force of the object might also be inaccurate if you use an unreliable weighing scale. Lastly, the apparatus might not be properly calibrated.
