Many amtrak trains can travel at a top speed of 47.0 m/s. assuming a train maintains that speed for several hours, how many kilometers will the train have traveled after 5.00 hours? round to the nearest km.

846 km

Explanation:

Speed = 47 m/s

time = 5 hours = 5 x 60 x 60 seconds

Distance = speed x time

Distance = 47 x 5 x 60 x 60

Distance = 846000 m

Distance = 846 km

found in the nucleus

has mass of one amu

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
