Answer:

A.3.64 m

Explanation:

Because

  • v=(fλ)
  • (1382)=(380)λ
  • λ=3.637m~3.64m

<em>where</em><em> </em><em>,</em><em>v</em><em>=</em><em>velocity</em>

<em>f</em><em>=</em><em>frequency</em><em> </em>

<em>λ</em><em>=</em><em>wave</em><em> </em><em>length</em><em> </em>

Answer:

3.64

Explanation:

the formula is Already provided which is Velocity(m/s)= frequency (HZ) × wavelength

making wavelength stand alone

wavelength= velocity/ frequency

wavelength= 1382/380

wavelength= 3.64

In the equation F = Kq1 q2/r2 solve for q2. Solve for r.
Tpy6a [65]

Answer:

r = √(k q₁ q₂ / F)

Explanation:

F = k q₁ q₂ / r²

Multiply both sides by r²:

F r² = k q₁ q₂

Divide both sides by F:

r² = k q₁ q₂ / F

Take the square root of both sides:

r = √(k q₁ q₂ / F)

The potential difference,electric current ,resistance and new electric current will be 12 V,4 A,3 Ω,2 A.

<h3>What is resistance?</h3>

Resistance is a type of opposition force due to which the flow of current is reduced in the material or wire. Resistance is the enemy of the flow of current.

The energy in terms of the charge and potential difference is;

E= qV

60=5 C × V

V= 12 V

The electric current is found as;

\rm I= \frac{q}{t} \\\\ I= \frac{5}{1.25}\\\\ I=4 \ A

From the ohm's law;

V=IR

12=4 ×R

R=3Ω

If the voltage is constant and the resistance is doubled, then the new electric current is half of the previous condition;

\rm I'=\frac{I}{2} \\\\ I'=\frac{4}{2} \\\\\ I'=2 \ A

Hence, the potential difference,electric current ,resistance and new electric current will be 12 V,4 A,3 Ω,2 A.
