Any <em>'</em><em>mechanical</em><em>'</em> wave needs a medium in order to travel from one place to another.
Examples of mechanical waves include . . .
-- ocean waves
-- sound waves
-- Slinky waves
-- guitar-string waves
-- hand waves
-- curtain waves
-- ripples on a pond
-- seismic waves (earthquakes)
Answer:
(a) 0.0001p W
(b) 0.1 W
(c) 1.6 W
Explanation:
(a) As there's only the flowrate 100 cm3/s (or 0.0001 m3/s), and the pressure is missing here, we shall assume that the pressure is p
The power is p*0.0001 = 0.0001p W
(b) p = 1000N/m2 and flow rate is 100 cm3/s or 0.0001 m3/s. The power shall be then
1000 * 0.0001 = 0.1 W
(c) p = 4000 N/m2 and flow rate = 400 cm3/s (or 0.0004 m3/s). The power shall be
4000 * 0.0004 = 1.6 W
Answer:Divergent boundaries -- where new crust is generated as the plates pull away from each other.
Convergent boundaries -- where crust is destroyed as one plate dives under another.
Transform boundaries -- where crust is neither produced nor destroyed as the plates slide horizontally past each other.

Answer:
Explanation:
Energy stored in a capacitor
= 1/2 CV²
C is capacitance and V is potential of the capacitor .
When capacitor is charged to 24 V ,
E₁ = 1/2 x 2.4 x 24 x24 = 691.2 J
When it is charged to 12 volt
E₂ = 1/2 CV²
.5 X 2.4 X 12 X12
= 172.8 J
