Answer:
Answer:
Without it information flow is impossible
Explanation:
The word 'pivotal' also means crucial or vital, and so we need to consider what an operating system actually does. Remember, merely having all the hardware of a computer would not allow you to run (install and use) programs. It is by means of an operating system that teaching programs can be installed, and it is also by means of an operating system learning can take place. For example, a student can decode (learn) instructions / lessons from his teacher via a software program; and the software program needs an operating system to open (run) the program.
Melting: as mantle material rise toward the divergent plate boundary the pressure is reduced which causes melting
Answer:
Average speed: 86 km/h
Explanation:
Driving from San Antonio to Houston:
1st. half time: 54km/h
2nd. half time: 118 km/h
Average speed = [tex] \frac{54 \frac{km}{h}+ 118 \frac{km}{h} }{2}=86 \frac{km}{h} [\tex]
Driving way back:
1st. half time: 54km/h
2nd. half time: 118 km/h
Average speed = [tex] \frac{54 \frac{km}{h}+ 118 \frac{km}{h} }{2}=86 \frac{km}{h} [\tex]
As in both routes we have the same average speed, then the average speed for the whole trip is 86 km/h
Answer:
Energy is an independent factor, that can only be reduced or increased, by change in normal reaction of a body.
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.
