I believe it’s 1 aka A part of it is reflected as Ray 2
An electric current produces a magnetic field when the current flows through a wire. The correct answer will be A.
Answer:
The electric field produced by this disk along the x axis at point (P = 1.01 m, 0.00 m) is 996.54 N/C
Explanation:
The electric field produced by this disk along the x axis at point (P = 1.01 m, 0.00 m), will be evaluated as follows:
Since x > 0
σ is surface charge density = 5.88 × 10⁻⁶ C / m²
R is the radius = 7.52cm = 0.0752m
position x = 1.01m
k is coulomb force constant = 8.99 × 10⁹ Nm² / C²
= 996.54 N/C
Therefore, The electric field produced by this disk along the x axis at point (P = 1.01 m, 0.00 m) is 996.54 N/C
<h2>
Relationship Between Frequency and Period</h2>
The frequency and the period are inversely proportional.
where T is the period
<h2>Solving the Question</h2>
We're given:
- <em>v</em> = 340 m/s
- <em>f</em> = 1000 Hz
Because the frequency and the period are reciprocals of each other, we can find the period of the sound by finding the reciprocal of the frequency:
