Answer:
The best angular magnification is
-375
Explanation:
Fe = Fo - L
From the question, (Fo) = 1.08 cm while (L) = 0.56cm
Thus, Fe = 1.08 - 0.56 = 0.52cm
Now, let's apply the angular magnification equation ;
M = - Di/Do
Where Di is the distance from the lens to the image and Do is the distance of the object to the lens.
In this question, Di is represented by f which is the distance from the lens to the image and it is f= 195cm
Also,Do is represented by Fe which is 0.52cm and it is the distance of the object to the lens.
Thus m = - f/fe = - 195/0.52 = - 375
Answer:
I think it's Law of Motion.

Answer:
B splits and goes through two components
Explanation:
- A series circuit is a circuit in which the components are all connected along the same branch: as a result, the current flowing through the components is the same, while the sum of the potential differences across each component is equal to the emf of the battery
- A parallel circuit is a circuit consisting of separate branches, so that each branch has a potential difference equal to the emf of the battery. As a result, in such a circuit the current in the circuit splits and goes through the different branches/components.
So, the correct answer is
B splits and goes through two components
The fundamental frequency of the open pipe A
Length 'L₀' is, f₀ = U/2L₀ = 340 H₂
the speed of sound in air V= 343m/s
∴343/2L₀ = 340 → length L₀ = 343/2 ×340 = 0.5044 = 50.44
The third harmonic of closed pipe 'B' is
F3₀ = 3V/4LC
The second harmonic of open pipe 'A' is
f2₀ = 2V/2L₀
∴ 3V/4LC = 2V/2L →L₀ = 3L₀/4
⇒ The length of closed pipe B is
Lc = 37.83cm
