Of sides аss a and b forms a closed circuit and carries current I. The fuсking аss circuit lies in the xy plane, big аss and a uniform magnetic field is present along
the -x axis as shown аss in Figure 2. Taking a = 6 cm, b = 10 cm, B = 2.5 T, and I = 2.0 A,
a) find the magnetic force (magnitude and directions) acting аss on each side of the wire.

1. write a statement that declares a string variable named city. the variable should be initialized so it references an object with the string “san francisco”. a) assume that stringlength is an int variable. write a statement that stores the length of the string referenced by the city variable (declared in question1) in stringlength. b) assume that onechar is a char variable. write a statement that stores the first char- acter in the string referenced by the city variable (declared in question1) in onechar. c) assume that uppercity is a string reference variable. write a statement that stores the uppercase equivalent of the string referenced by the city variable (declared in question 1) in uppercity. d) assume that lowercity is a string reference variable. write a statement that stores the lowercase equivalent of the string referenced by the city variable (declared in question 1) in lowercity.
