Answer:
Explanation:
Volume per unit time flowing will be conserved
a₁v₁ = a₂ v₂
π r₁² x v₁ = π r₂² x v₂
(0.9 x 10⁻²)² x .35 = ( .45 x 10⁻² )² x v₂
v₂ = 1.4 m / s

Answer:
the power of the solar cell is 1.5 watts
Explanation:
Recall that power is defined as the product of the voltage (V) times the running current (I): Power = V * I.
The only thing we have to take care of before actually performing the operation, is to convert milliamps into Amps, so our answer comes directly in the appropriate units (Watts). 500 mAmps can be written as 0.5 Amps, then, the product becomes:
Power = V * I = 3 V * 0.5 Amps = 1.5 watts
