Light of wavelength 675 nm passes
through a double slit, and makes its
first minimum (m = 1) at an angle of
0.111 deg. What is the separation of
the slits, d, IN MILLIMETERS?
(Remember, milli means 10-3.)
(Unit = mm)

What is the most useful equation for electric power?

Acyclotron is used to produce a beam of high-energy deuterons that then collide with a target to produce radioactive isotopes for a medical procedure. deuterons are nuclei of deuterium, an isotope of hydrogen, consisting of one neutron and one proton, with total mass 3.34×10−27kg. the deuterons exit the cyclotron with a kinetic energy of 6.40 mev .a-what is the speed of the deuterons when they exit? b-if the magnetic field inside the cyclotron is 1.25 t, what is the diameter of the deuterons' largest orbit, just before they exit? c-if the beam current is 350 μa how many deuterons strike the target each second?

Do you think you could give me the answers to #29?
