This question is incomplete, the complete question is;
A flat coil is in a uniform magnetic field. What angle between the magnetic field and the plane of the coil produces the maximum flux, and what angle produces 90% of the maximum flux
A) max: 0°
90% of max: 90°
B) max: 90°
90% of max: 45°
C) max: 90°
90% of max: 64°
D) max: 0°
90% of max: 26°
E) max: 90°
90% of max: 80°
Answer:
Option C) max: 90°
90% of max: 64° is the correct Answer
Explanation:
from the Suppose Area is A.
then flux at angular position O is
Ф = BAsin∅
⇒ Ф = βmaxSin∅
flux will be max when sin∅ = 1
therefore sin∅ = 1
∅ = sin⁻¹ 1
∅ = 90°
Now at 90% of max flux
Ф ⇒ 0.9βmax = βmax sin∅
0.9 = sin∅
∅ = sin⁻¹ (0.9)
∅ = 64.15° ≈ 64°
Therefore Max ∅ = 90°
90% flux = 64°
Option C) max: 90°
90% of max: 64° is the correct Answer
I believe that the answer to this would be option C. Since sandstones are not commonly seen among river beds, the condition that would make us easier to understand as to what happened to this is how fast the river was flowing. Due to the pressure of the river, this brought other sediments with it most especially sandstones.
Answer:
C. Television
Explanation:
Mostly in cathode ray television, a TV has many of different types of capacitors, used as connections between circuits, as timing components and as electronic filters. TV capacitors perform many functions.
capacitor acts as a reservoir for electric charge, storing and releasing electricity in precise amounts.
What is a Capacitor ?
A capacitor is a simple device consisting of a pair of metal foils separated by a thin insulator, such as plastic, used basically for storing charge
Pitch is way to relate a sound to its frequency. High frequencies have high pitches (think of a flute), and low frequencies have low pitches (think of a bass). <span>
