Answer:
is always negative
Explanation:
Air resistance is a non-conservative force it opposes the motion of an object.It is a force that is always directed opposite to the displacement.
The focal length of the eye-lens system will be exactly 2.0 cm. The lens thickness is altered depending on the distance of the object being viewed so that the focal length is ALWAYS equal to the lens-retina distance. If this is not true fr an individual, they need glasses :)
The circuit shown has a battery and two resistors, with R1>R2. Which of the two resistors dissipates the larger amount of power? Explain
Rank in order, from largest to smallest, the three currents I1 TO I3. And explain why?
The two batteries are identical and the four resistors all ahve exactly the same resistance.
a) Compare change in V(ab), V(cd), and V(ef). Are they all the same? In not, rank them in decreasing order. Explain you reasoning
b) Rank in order, from largest to smallest, the five currents I1 to I5, and ezplain why
