As an atom's nucleus gets larger the electric charges repelling the protons get larger. To compensate for this greater electric charge the atom.
A.) needs more neutrons to gain enough nuclear binding forces to overcome
the repulsion.

B.) needs fewer neutrons to gain enough nuclear binding forces to overcome
the repulsion.

C.)needs more electrons to gain enough nuclear binding forces to overcome
the repulsion.

D.)needs fewer electrons to gain enough nuclear binding forces to overcome
the repulsion.

Consider a uniformly charged ring in the xy plane, centered at the origin. the ring has radius a and positive charge qdistributed evenly along its circumference. a)what is the direction of the electric field at any point on the z axis? . b)what is the magnitude of the electric field along the positive z axis? use k in your answer, where k=14πϵ0. d)the ball will oscillate along the z axis between z=d and z=−d in simple harmonic motion. what will be the angular frequency ω of these oscillations? use the approximation d≪a to simplify your calculation; that is, assume that d2+a2≈a2. express your answer in terms of given charges, dimensions, and constants

Wo small variable-thrust jets are actuated to keep the spacecraft angular velocity about the z-axis constant at ? 0 = 1.16 rad/s as the two telescoping booms are extended from r1 = 1.18 m to r2 = 4.69 m at a constant rate over a period of 124 seconds. the small 19-kg experiment modules at the ends of the booms may be treated as particles, and the mass of the rigid booms is negligible. determine the necessary thrust t for each jet as a function of time where t = 0 is the time when the telescoping action is begun. after you have the general expression for t, answer the questions. show work.
