A runner completes two laps around a 400 m track. she runs the first lap in 1 min and 32 s, and the second lap in 1 min and 49 s. what is her average speed

explanation:

newton's third law, for every action there is an equal and opposite reaction.

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.

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.
