A charged particle with a charge-to-mass ratio of |q|/m = 5.7 x 10^8 C/kg travels on a circular path that is perpendicular to a magnetic field whose magnitude is 0.69 T. How much time does it take for the particle to complete oneChemistry
An alpha particle (mass 6.6 x 10^-24 grams) emitted by radium travels at 3.4 x 10^7 plus or minus 0.1 x 10^7 mi/h. (a) What is its de Broglie wavelength (in meters)? (b) Whats uncertainty in its position? for part (a) I got 1.53Physics help!
An alpha particle(charge +2e) is sent at a speed towards a gold nucleus( +79e ). 1) what is the electric force acting on the alpha particle when it is 2.0 x 10^-14 m from the gold nucleus. 2) if the alpha particle came to a stopPhysics
A uranium nucleus (mass 238 u, charge 92e) decays, emitting an alpha particle (mass 4 u, charge 2e) and leaving a thorium nucleus (mass 234 u, charge 90e). At the instant the alpha particle leaves the nucleus, the centers of the Google chrome linux old version.
Radium 3 1 3 X 48
2 Radium P-16 16ch radios, with chargers and Li-ion batteries. 1 RAD-101 behind-the-head headset, with com cord. 1 helmet kit with S3 Microphone, avaialable in IMSA or NASCAR. 1 SCC-EFEPV2 Foam Ear Buds. 1 Double shileded car harness, avaialable in IMSA or NASCAR. 1 Radio to harness interface. 1 PTT switch, avaialable in velcro or hole mount styles. One gram of radium-226 undergoes 3.7 × 10 10 disintegrations per second, a level of activity that defined the curie (Ci), an early unit of radioactivity. This is an energy release equivalent to about 6.8 × 10 −3 calorie per second, sufficient to raise the temperature of a well-insulated 25-gram sample of water at the rate of 1 °C every hour.
