An alpha particle (the nucleus of a helium atom, with charge +2e and a mass four times that of a proton) and an antiproton (which has the same mass as a proton but charge -e) are released from rest a great distance apart. They are oppositely charged, so each accelerates toward the other.What is the speed of the alpha particle when the particles are 1.1nm apart? What is the speed of the antiproton when the particles are 1.1nm apart?
A block and a gun are firmly affixed to opposite ends of a long glider mounted on a frictionless air track. find the mass of the gun-glider-block system
A certain car battery with a 12.0 V emf has an initial charge of 178 A•h. assume that the potential across the terminals stays constant until the battery is totally discharged, for how long in hours can it deliver energy at the rate of 115 W.
A destroyer sends a sonar pulse out to detect a submarine directly below the ship in the ocean. If the speed of sound in what is 1517 m/s and it takes 64.13 s for the return pulse to hit the hydrophone on the bottom of the ship, how deep is the su..
