Calculate the probability of an electron in the ground state of the hydrogen atom being inside the region of the proton. (For purposes of calculation, use a proton radius r = 0.990e-15 m. Hint: Note that r << a0.)
A proton accelerates from rest in a uniform electric field of 628 N/C. At some later time, its speed is 1.10106 m/s. What is its kinetic energy at the later time
A blue ball is thrown upward with an initial speed of 22.8 m/s, from a height of 0.9 meters above the ground. 2.8 seconds after the blue ball is thrown, How long after the blue ball is thrown are the two balls in the air at the same height
A 352-kg motorcycle is accelerating up along a ramp that is inclined 30.0º above the horizontal. Find the magnitude of the motorcycle's acceleration
An object of mass 1.0kg is attached to a spring with spring constant 15 N/m. what is the amplitude of oscillation
An oscillating mass-spring system has the following:displacement x=10cm; linear speed v=-20m/s, and an acceleration a=-20 m/s^2 what is the period of oscillation of the system
Connections to the body for electrocardiography (ECG) and electroencephalography (EEG) are normally made with metal electrodes and conductive gels to ensure good electrical contact. Whats the minimum electrode capacitance
Four uncharged capacitors with equal capacitances are combined in parallel. The combination is connected to a 5.47-V battery, which charges the capacitors. The charging process involves 3.25 × 10-4 C of charge moving through the battery. Find the cap..
