Answer:
Echocardiography
Explanation:
Echocardiography is a painless test that uses the sound waves called ultrasonic waves with a frequency exceeding 20 kHz is used to produce images of the heart.
The echocardiography is also known as the ultrasound of the heart which is performed to check the blood clots, the aorta related pictures and the functioning of the valves of the heart.
The picture produced by this echocardiography is known as the echocardiogram and is used to treat heart disease.
Thus, Echocardiography is the correct answer.
Answer:
the directionality problem
Explanation:
In directionality problems, there are two variables and when these two variables are co-related then it becomes impossible to decide which variable is the cause of the particular problem and which variable is the effect of the problem.
So here there are two variables depression and insomnia but scientists can not determine that out of insomnia and depression which is the cause of the problem and which is the effect of the problem so it is unclear that whether the depression causes insomnia or the lack of sleep causes depression. Therefore this is an example of directionality problem
.
It’s c
Because velocity; just like speed will be distance over time
However on this case it’s displacement over time
Anyway in case ur wondering ,
the only difference between distance and displacement is that displacement requires a direction
so
100m/4s
=25 m/s to the east since the direction is already mentioned in question
