Answer:
A flat, horizontal line
Explanation:
A flat, horizontal line indicates a phase change.
The temperature does not increase because the added heat goes into converting one phase into another.
A is wrong. A downward-sloping line indicates that the temperature is decreasing with time.
C is wrong. An upward-sloping line indicates that the temperature is increasing with time.
Hi!
The correct option would be C.
<h3>Explanation:</h3>
Scientific method is the protocol in an experiment for a hypothesis that involves testing, measurement, observation and necessary modification of hypothesis during the course of the experiment. There are several manners and experiments that can be tested for the hypothesis, and plenty of ways to design an experiment.
Scientific experiments can be very tricky to design, owing to the numerous parameters and variables that need to be accounted for. Of course, there are some relatively simple experiments. Creativity is needed for all branches of science, because each field presents obstacles in discovery, and creativity allows for us to devise ways around those obstacles. Science has always tested humans ability to think outside the box and question their surroundings, and creativity has been the driving force.

Answer: 15.87 m
From the equation of motion:
where, 
is the distance traveled, 
is the initial velocity, 
is the acceleration and 
is the time.
The rock free falls under gravity. Initial velocity, 
, 
It took 
for rock to hit the water.
Substitute the values in the given equation:
Hence, the water is 15.87 m below the top level of the well.
