A beam of electromagnetic radiation is directed onto two slits that are 0.31mm apart, creating an interference pattern on a screen 6.0m away. If maxima #3 is 1.9cm from the central bright spot, what is the wavelength of the light?

hi i’m sorry to call us today so we will get back with y’all and we will have to do it haha omg was the day

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2

what is the actual question though?

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
