The limit to the eye's acuity is actually related to diffraction by the pupil. 1. what is the angle between two just‑resolvable points of light for a 3.75 mm diameter pupil, assuming the average wavelength of 524 nm ? 2. take the result to be the practical limit for the eye. what is the greatest possible distance a car can be from a person if he or she can resolve its two headlights, given they are 1.30 m apart? 3. what is the distance between two just‑resolvable points held at an arm's length (0.900 m) from a person's eye? mm

Two conductors, a and b, are each in the shape of a tetrahedron. but of different sizes. they are charged in the following manner: 1. tetrahedron a is charged from an electrostatic generator to charge q. 2. tetrahedron a is briefly touched to tetrahedron b. 3. steps 1 and 2 are repeated until the charge on tetrahedron b reaches a maximum value. if the charge on tetrahedron b was q/4 after the first time it touched tetrahedron a. what is the final charge qbmax on tetrahedron b?

Choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. a 1.0 kg block is placed on top of a 2.0 kg block. a horizontal rope pulls the 2.0 kg block across a frictionless floor with a force of 21.0 n. the coefficient between the two blocks is 0.75. does the 1.0 kg block on top slide?

How much work would it take to move a coulomb charge across a 4 volt potential difference?
