Blank is something empty lol
Answer:
Balancing of forces,
In the X-direction:
-Tcos4.5^o +Tcos4.5^o=0
In the Y-direction:
Tsin4.5^o +Tsin4.5^o-m*g=0
2Tsin4.5^o=15*9.81
T=(15*9.81)/(2sin4.5^o)
=937.75 N
Therefore, tension in the rope is 937.75 N.
Answer:
Fracturing can emit seismic waves through the ground.
Explanation:
I believe the answer is seismic, I've studied this before.
D = RT
D is 8.4 cm or 84mm, R is 3.5mm (units of time, assuming seconds for now)
84 = 3.5T
T = 24 seconds
