Answer:
Bent knees
Explanation:
Depending the height your jumping from, if you were jumping from a high structure it's best if you jump and land on knees so you dont sprang your ankles from jumping and landing on your straight legs, you could even pull a muscle if you land on straight legs.
Answer:
4 Ohms
Explanation
(This is seriously not as hard as it looks :)
You only need two types of calculations:
- replace two resistances, say, R1 and R2, connected in a series by a single one R. In this case the new R is a sum of the two:

- replace two resistances that are connected in parallel. In that case:

I am attaching a drawing showing the process of stepwise replacement of two resistances at a time (am using rectangles to represent a resistance). The left-most image shows the starting point, just a little bit "warped" to see it better. The two resistances (6 Ohm next to each other) are in parallel and are replaced by a single resistance (3 Ohm, see formula above) in the top middle image. Next, the two resistances (9 and 3 Ohm) are nicely in series, so they can be replaced by their sum, which is what happened going to the top right image. Finally we have two resistances in parallel and they can be replaced by a single, final, resistance as shown in the bottom right image. That (4 Ohms) is the <em>equivalent resistance</em> of the original circuit.
Using these two transformations you will be able to solve step by step any problem like this, no matter how complex.
The asthenosphere is thicker than the lithosphere, where the speed was faster.
<h3>
Velocity of S wave</h3>
The velocity of s wave decreases as the thickness of the Earth layer increases, because it will take more time to travel through the given thicker formation.
The magnitude of velocity is given as;
v = x/t
where;
- x is the thickness of the Earth layer
- t is the time of motion
This implies that the speed of the s wave will high in thin formation and low in thick formation (layer).
When the velocity of S wave decreases as the waves leave the lithosphere and enter the asthenosphere, it implies that the asthenosphere is thicker than the lithosphere, where the speed was faster.
