Answer:
0.82A
Explanation:
first we resolve the resistors in parallel
i.e 1/R=1/R1+1/R2
=1/R=1/6+1/3
1/R=1/2
R=2/1=2ohms
now we resolve all resistors in series
R=R1+R2+R3
R=6+3+2(the two parallel resistors we resolved are now in series with the others)
R=11ohms
From ohm's law V=IR
I=V/R=9/11= 0.82A.
Answer:
394.26 m
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 9.8 m/s²
Total time taken by the stone to reach the ground is 4.49+4.49 = 8.97 seconds
The times are equal so,
The height is 394.26 m
Answer:
its a solid it travals fasters in a solid
Explanation:
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
