Please help me quickly will mean alot!! THE VOLTAGE ACROSS THE GROUPING U=12 VOLTE
TAKE R1=39
AND R2=68
The question is
CALCULATE i1 and i2

​

What is a good example of instantaneous speed

Another word for electromagnetic energy is a. heat b. force c. matter d. radiation

An alpha particle with kinetic energy 12.5 mev makes a collision with lead nucleus, but it is not "aimed" at the center of the lead nucleus, and has an initial nonzero angular momentum (with respect to the stationary lead nucleus) of magnitude l = p0 b, where p0 is the magnitude of the initial momentum of the alpha particle and b=1.40×10−12 m. (assume that the lead nucleus remains stationary and that it may be treated as a point charge. the atomic number of lead is 82. the alpha particle is a helium nucleus, with atomic number 2.) what is the distance of closest approach?
