Answer:
The same in both the regions of constructive interference and the regions of destructive interference.
Explanation:
Interference is a phenomenon which occurs when two waves meet while moving along the same medium . The amplitude formed as a result of the interference could be greater, lower, or the same amplitude.
Constructive and destructive interference result from the interaction of waves that are correlated or coherent with each other. This is because arose from the same source or they have the same or nearly the same frequency.
The waves being coherent, arising from the same source and having the same frequency explains why it’s the same in both the regions of constructive interference and the regions of destructive interference.
Answer: 8Ω
Explanation:
Since there are two resistors of 4Ω
connected in series, the total resistance (Rtotal) of the circuit is the sum of each resistance.
i.e Rtotal = R1 + R2
R1 = 4Ω
R2 = 4Ω
Rtotal = ?
Rtotal = 4Ω + 4Ω
Rtotal = 8Ω
Thus, the total resistance of the circuit is 8Ω
Answer:
± (.021 ) ohm
Explanation:
In the addition of two physical quantities , the uncertainties are simply added .
So , net uncertainty in the value of R will be
± (.007 +.014)
=± (.021 ) ohm
Answer:
Orange juice has a lower viscosity than chocolate syrup.
Explanation:
Viscosity is the measure we use to determine essentially how thick a fluid is. So, a liquid that has a high viscosity, is thicker than a liquid that has a lower viscosity. Viscosity is also benchmarked against that of water since water is considered to he the least viscous fluid. Therefore, the more "watery" the substance, the less viscous it is.
Its easy to imagine how orange juice would have a lower viscosity. When we imagine, we think about how quickly both orange juice and chocolate syrup would flow if they both were to be spilled. Basically, we would be looking at their "flow rate" where orange juice would wash away quickly while chocolate syrup would tend to stick to the surface and be slower. But lets also look why this happens. This happens because of the size of the particles. Orange juice is diluted and has a lot of water molecules which are small and can move very quickly. Chocolate syrup on the other hand is comprised of molecules that are larger and heavier and therefore take a longer time to move. So a liquid with lower viscosity is "less resistant to flow".
