Say no = 1.00x10' muons traveling at 0.999c are measured at 5000 m above sea level. the number of muons surviving after a time tis n= no exp[- ]where #12 = 1.52 10-s is known as the muon half-life. how many would you expect to reach sea level using galilean relativity and how many using einstein's special relativity?

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2

explanation:

wheres the pic

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.
