a monosynaptic reflexes, it is like me speaking to you over a
telephone. I am the only talker and you are the only listener. The
phone line only has to connect to 2 people. If I am the one talking, I
would be the sensory neuron, and if you are listening you would be the
motor neuron. I can tell you what to do really fast because it is only 1
person I have to give instructions to. An example of this is the
patellar reflex. The doc hits the patella and your leg kicks. This is
becuse the sensory neuron gets hit and he quickly tells the motor neuron
to kick. It happens really, really fast. Another example is touching a
hot stove, what happens? Before you can even think to yourself that
the stove is hot, your hand will pull away. Monosynaptic reflexes are
made for very quick responses to stimuli that will not need to be
stopped or thought about in order to react.

I can answer the first question: Water rises because of the sun's heat and turns into water vapor. After that, it gathers up and forms a cloud. When the cloud is filled enough with vapor, precipitation occurs.
Answer:
See the answer below
Explanation:
If you step on the brake of a car while driving, the frictional force between the tires of the car and the surface of the road increases in opposition to the motion of the car. Consequently, the car slows down.
If you release your foot from the brake pedal when the car is still at half speed, the frictional force reduces and the car speeds up a bit even without pressing the throttle. Eventually, the frictional force will slow down and stop the car if the throttle is not pressed.
Answer:
The velocity with which the ball strikes the ground = -5.7 m/s
The velocity with which the ball leaves the ground = 4.3 m/s
Explanation:
Seems like there's parts of a couple questions. I'll focus on the tennis ball part which seems to be a full question.
To find the velocity with which the tennis ball hits the ground, we only need to worry about what happens up to that point. We can ignore the rebound for this part. Given:
d = -1.85
a = -9.8
vi = 0
vf = ?

*Keep in mind that the square root gives us two answers, a positve and a negative one. We use the negative one here because the final speed is downwards and the question says down is negative.
To find the velocity with which the ball leaves the ground, we only need to worry about what happens after that point. We can ignore the drop for this part. Given:
d = 0.947
a = -9.8
vf = 0
vi = ?

*Here we use the positive speed after the square root because we know the ball is going up, which the question designates as the positive direction.
