Answer:0.0144 tesla
Explanation:
Magnetic field strength is the same as Magnetomotive force
B= I/2πr
B=magnetic field strength
I=current
r=radius=0.15/2=0.75m
Area=πr2= 1.77m2
torqueT= NIABsin theta
B= T/NIABsin theta
B=0.135/1 * 5.3 * 1.77 *sin90
B=0.0144 tesla
Answer:
By a factor 9
Explanation:
The intensity of a sound wave is proportional to the square of the amplitude of the wave:

where
I is the intensity
A is the amplitude of the wave
In this problem, the amplitude of the sound wave is increased by a factor 3:
A' = 3A
So the intensity would change by

So, the intensity would increase by a factor 9.
Answer: m∠P ≈ 46,42°
because using the law of sines in ΔPQR
=> sin 75°/ 4 = sin P/3
so ur friend is wrong due to confusion between edges
+) we have: sin 75°/4 = sin P/3
=> sin P = sin 75°/4 . 3 = (3√6 + 3√2)/16
=> m∠P ≈ 46,42°
Explanation:
The correct answer would be A) the lenses of the eye change the size of images
Like windmills they use the winds to generate their power.
