Answer: The correct answer is "The surface of the lake is smooth".
Explanation:
The light gets reflected from the smooth surface at the same angle as it hits that surface. If the light gets reflected in all direction from the rough surface when it hits the surface. Then, there will be diffuse reflection.
In the given problem, Leon sees a poster that shows a lake in front of a snow-capped mountain. The mountain appears upside down in the lake. Here, the water acts like a mirror. The light rays incident on the surface of the water from the mountainthen the reflected rays get reflected back from the smooth surface of the lake. Here, the angle of incidence is equal to the angle of the reflection.
One can see the image of the object on the surface of the lake.
Therefore, the correct option is (A).
Answer:
the answer is a.

yes
evaporation starts on the surface
B. 19.6 m/s
C. 4.9 m/s
D. 9.8 m/s
i just did the quiz and so the only 2 options that made logical sense would be B (19.6 m/s) or D (9.8 m/s) the reason someone could get confused between these two is because 19.6 divided by 2 is 9.8 m/s so for each second it will go down 9.8 m/s but since it wants to know the velocity it would be 19.6 m/s
hope this helps
Explanation:
Three resistors of resistances 2ohm,3ohm, and 6ohm respectively.
Let R1=2Ω
⇒R2=3Ω
⇒R2=6Ω
● A total resistance of 4Ω from three resistors of given resistances. Firstly, connect the two resistors of 3Ω and 6Ω in parallel to get a total resistance of 2Ω which is less than the lowest individual resistance.
●When R 2 and R 3 are connected in parallel with
R1 in series we get
⇒1/R=1/R2+1/R3
⇒1/R=1/3+1/6
⇒1/R=1/2
⇒R=2Ω
●Hence, the total resistance of the circuit is 4Ω.
