Answer:
decrease the area in the second cylinder
Explanation:
In a two-cylinders pneumatic system, the pressure exerted on the first cylinder is equal to the pressure on the second cylinder:
We can rewrite the pressure as product between force (F) and area (A) of the cylinder:
In this system, the output force should be 4 times the input force:
Substituting into the previous equation, we get:
This means that the area of the second cylinder must be 1/4 of the area of the first cylinder, so the correct answer is
decrease the area in the second cylinder

Answer:
(a) The magnitude of the electric dipole moment is 1.68 x 10⁻¹⁴ C.m
(b) The difference between the potential energies ΔU, is 4.6704 x 10⁻¹¹ J
Explanation:
Given;
magnitude of charge, q = 2 nC = 2 x 10⁻⁹ C
distance of separation, d = 8.4 μm = 8.4 x 10⁻⁶ m
strength of electric field, E = 1390 N/C
(a) the magnitude of the electric dipole moment
p = qd
p = (2 x 10⁻⁹ C)(8.4 x 10⁻⁶ m)
p = 1.68 x 10⁻¹⁴ C.m
(b) the difference between the potential energies for dipole orientations parallel and anti-parallel to E
ΔU = U(180) - U(0)
ΔU = 2pE
ΔU = 2(1.68 x 10⁻¹⁴ )(1390)
ΔU = 4.6704 x 10⁻¹¹ J
The external auditory meatus, or ear canal, funnels sound to the eardrum. It is part of the outer ear.
Answer: the conflict began when a british representative - Sr. Frederick Mitchell Hodgson sat on the golden stool.
Explanation:
since the stool wasn't a throne, when Yaa Asantewaa found out, he led a rebellion which killed 1000 British and allied African soldiers and 2,000 Ashanti.
good luck with your assignment :)
