In Medicine, "etiology" means the origin or cause of a disease.
Similar to Hippocrates, modern scientists who study etiology believe that diseases come from natural causes such as bites from infected insects.
Answer: maximum amplitude of seismic waves as they reach seismographs. So the category the earthquake is such as a 6.0 or a 7.0.
Explanation:
Answer:
Explanation:
Length if the bar is 1m=100cm
The tip of the bar serves as fulcrum
A force of 20N (upward) is applied at the tip of the other end. Then, the force is 100cm from the fulcrum
The crate lid is 2cm from the fulcrum, let the force (downward) acting on the crate be F.
Using moment
Sum of the moments of all forces about any point in the plane must be zero.
Let take moment about the fulcrum
100×20-F×2=0
2000-2F=0
2F=2000
Then, F=1000N
The force acting in the crate lid is 1000N
Option D is correct
Answer: The Earth's layer, which has the covering and layer, is made of a progression of things, or structural plates, that creep after some time. Along these lines, at intersecting limits, mainland outside is made and maritime covering is devastated. 2 plates slippy past each other structures a redesign plate limit.
<span>I think the average velocity b/w t =a and t= b would be
Avg vel. = change in vel./ change in time</span>
