I think the answer is c. the more characteristics they have in common. Sorry if wrong.
<span>dc = direct current
ac = alternate current</span>
Answer: 248 Newton
Explanation:
force = rate of change of momentum
change of velocity
= 4 + 4 = 8 m/s
rate of change of momentum = mass per second x change of velocity
= 31 kg/s x 8 m/s
= 248 kg m/s^2 or Newtons
Answer:
The Reynolds number determines what type of regime is laminar or turbulent in a flow pattern.
Explanation:
The Reynolds number determines what type of regime is laminar or turbulent in a flow pattern.
In the laminar regime R_D <2300 the flow is ordered and has an envelope predicted by the expressions
In the turbulent regime R_D> 2900 the flow has vortices and is extremely irregular
in the intermediate values it is in a transition regime
