Answer:
1. 571.43m/s
2. 142.9m and 342.9m
Explanation:
1.Take the difference in time.
1.2-0.7=0.7 seconds
Take the distance between them and divide with differnce in time.
400÷0.7=571.43 seconds.
2.Take the time of the two men and divide by two.
0.5÷2= 0.25 secs
1.2÷2= 0.6 secs
multiply each with the velocity.
0.25×571.43=142.9m
0.6×571.43=342.9m
Organ system is the correct response hope this helps
Answer:
wavelength is equivalent to the velocity divided by the frequency
I’m pretty sure
Part 1; C
Part 2; C
Not 100% sure tho :)
I think the force of spinning it can only hold for so long and because of gravitys pressure.(i hope i helped) :)
