Answer:
Not sure what yours looking for but When a disease is widespread, epidemiological studies investigate what associated factors, such as location, swx, exposure to chemicals and many others, make a population more or less likely to have an illness, condition, or disease thus helping determine its etiology.
For 2, i think that the reason the ultrasound can make an image is by using the waves that it can use to pick up (???)
idk, that's what i think anyway, i hope i helped ^^
Initial velocity of kangaroo in upward direction (u) = 5.77
Final velocity at the highest point of the journey (v) = 0
Let the maximum height reached be H.
Acceleration due to gravity = -9.8
Now, using the third equation of motion:
H = 1.698 m
The maximum height reached by kangaroo is 1.7 m.
Answer:
a) 0 J
b) 0.92J
Explanation:
The work is defined as:
because the normal force is perpendicular to the displacement the work done for it is zero.
The force because of frictions has an angle of 180 degrees because it is opposite to the motion, so:
