Aclosely wound, circular coil with radius 2.0 cm has 1000 turns. a current of 5.0 a flows through the coil. (a) what is the magnetic field at the center of the coil? (0.15 t) (b) what is the magnetic field on the axis of a coil at a distance of 5.0 cm from the center of the coil? (8 x 10-3 t)

Two particles of masses m and 2m are placed on a smooth horizontal table. a string, which joins these two masses, hangs over the edge supporting a pulley, which suspends a particle of mass 3m.the pulley has negligible mass. the two parts of the string on the table are parallel and perpendicular to the edge of the table. the hanging parts of the string are vertical. find the acceleration of the particle of mass 3m.

Natural forces that can alter ecosystems include seasons and climate changes. t or f

What is the magnitude of the acceleration vector which causes a particle to move from velocity −5i−2j m/s to −6i+ 7j m/s in 8 seconds. answer in m/s.
