The greatest increase in the inertia of an object would be produced by increasing the
(1)mass of the object from 1.0 kg to 2.0 kg
(2)net force applied to the object from 1.0 n to 2.0 n
(3)time that a net force is applied to the object from 1.0 s to 2.0 s
(4)speed of the object from 1.0 m/s to 2.0 m/s

Aphoton is absorbed by an electron that is in the n = 3 state of a hydrogen atom, causing the hydrogen atom to become ionized. very far away from the nucleus, the released electron has a velocity of 750,000 m/s. what was the wavelength of the absorbed photon?

When using the scientist method, which step comes last?

Athin nonconducting rod with a uniform distribution of positive charge q is bent into a circle of radius r. the central perpendicular axis through the ring is a z-axis, with the origin at the center of the ring. a) what is the magnitude of the electric field due to the rod at z = 0? n/c (b) what is the magnitude of the electric field due to the rod at z = infinity? n/c (c) in terms of r, at what positive value of z is that magnitude maximum? r (d) if r = 4.00 cm and q = 9.00 µc, what is the maximum magnitude? n/c
