Given that the lenth write steel l =3.80m fastened celling mass m= 54.0kg v = s/t v = 3.8/0.0492 v = 77.23 m/s now, the formula for speed in a wire is v = ( T/ÎĽ )^1/2 where T is the tension in the string and ÎĽ is the mass pee unit length. v = ( Tl/m )^1/2 .......(replace ÎĽ with m/l) now T = 550N v = [ 550(3.8)/m ]^1/2 squaring both sides v^2 = 550(3.8)/m v^2 = 2090/m putting the value of v calculated above and solving m =0.35 kg
As elements in period are arranged according to increasing atomic weight with isotope as protium deuterium and trotium of h2 so chemical property are same but physical property different in period ic table
<span>If you have only two
data from two recording stations then you will be having a hard time finding
the correct location of the epicenter. This is because triangulation method requires
3 recording station. If you have 2 recording station, the 2 circles will
intersect at 2 points giving you 2 locations that could possibly be the
epicenter.</span>
With this you are wrong and he is right because work is not like displacement where if you go 10 ft to the right then 10 ft to the left you have traveled gone 0 ft from original spot. because your distance was 50 m and you exerted 800 N you multiply that together and come out with 40,000 so HE IS RIGHT YOU ARE WRONG.
