A 60 kg person and an 75 kg person each jump off opposites sides of a 40 kg raft with a speed of 3.0 m/s. If the raft was initially at rest, what is the final speed of the raft? Was this collision elastic? Explain.​

the higher the current the higher the mag field around it the higher the influence on the compass

b.a device that inputs heat into a cool object

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7

in four significant figures
