Which statement about seismic waves is false?
a. p waves travel faster, so the gap between their arrival times gives the source's distance.
b. only p waves can be detected in the shadow zone.
c. close to the epicenter, both s and p waves can be recorded.
d. both s and p waves can be detected by seismographs.
e. s waves are blocked by the fluid outer core and cannot be observed on the other side of the planet from the epicenter.

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.

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
