Answer:
C) >A)>B)
Explanation:
We know that force per unit area is known as pressure.But we have to understand that this force should be perpendicular to the area.
P = F/A
P=Pressure
F= Force
A=Area
A)
Given that
ΔP=2.9 N/m²
A=1500 m²
F= ΔP x A
F= 2.9 x 1500
F=4350 N
B)
Given that
ΔP=4.7 N/m²
A=900 m²
F= ΔP x A
F= 4.7 x 900
F= 4230 N
C)
Given that
ΔP=8.8 N/m²
A=500 m²
F= ΔP x A
F= 8.8 x 500
F=4400 N
4400 N > 4350 N > 4230
C) >A)>B)
Without knowing anything about their magnitudes or directions, the only thing you can always say about thier combination is that it's the "net force" on the object.
The answer is D. If you aren't consistent with your drop positions, then your data may be invalid. To be frank: it basically screws over the experiment.
I'm probably going to have to say C. E as it seems the steepest right around there. If I'm wrong on that, it has to be B. B
I think your answer would be (D) microscope with a video camera
Hope i helped!
