Alfred Wegener first presented his hypothesis to the German Geological Society on 6 January 1912. His hypothesis was that the continents had once formed a single landmass, called Pangaea, before breaking apart and drifting to their present locations.
Answer:
The pressure on each side of the clot is same.
Explanation:
The clot is moving with a constant velocity which implies that the total force on the clot is zero.
The force F is given by the formula.
F=ΔPA
where ΔP is the difference in pressure and A is the area.
Since the force is same on either side, therefore,
ΔPA=0
Also, the area is same on both side of the clot.
Therefore the difference in the pressure of both side is zero which implies that the pressure on both sides are equal.

Answer:
Work done is zero
Explanation:
given data
Angle of kite with horizontal = 30 degree
tension in the string = 4.5 N
WE KNOW THAT
Work = force * distance
horizontal force = 
DISTANCE = 0 as boy stands still. therefore
work done = 3.89 *0 = 0
Control group in a scientific experiment is a group separated from the rest of the experiment, it is where the independent variable being tested cannot influence the results. It isolates the independent variable's effects on the experiment and can helps rule out alternative explanations of the experimental results.
One is just for counseling and the other is clinical. I'm sure that with a clinical psychologist you HAVE to see them as a counseling psychologist, you can choose to see them.
