Ors and two batteries connected in a circuit. What are the currents Is. 12, and 13? (Consider the following values: R1= 1.16 ohm R2 = 2.120, R3 = 3.09 , R4= 4.200, R5= 6.160. Due to the nature of this problem, do not use rounded intermediate values in your calculations-L

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?

The diagram shows four locations in the electric field of a positive point charge m. at which location is the electric potential the greatest.

Question part points submissions used suppose that 2 j of work is needed to stretch a spring from its natural length of 26 cm to a length of 36 cm. (a) how much work is needed to stretch the spring from 28 cm to 32 cm? (round your answer to two decimal places.)
