Explain how a voltage is produced in the secondary coil of the transformer.

Tema [17]

Answer:

the primary coil current produces a magnetic field, which changes as the current changes. the iron core increases the strength of the magnetic field. the changing magnetic field induces a changing potential difference (voltage) in the secondary coil.

What is (Fnet3)x, the x-component of the net force exerted by these two charges on a third charge q3

Pachacha [2.7K]

This question is incomplete, the complete question is;

Coulomb's law for the magnitude of the force F between two particles with charges Q and Q' separated by a distance d is

|FI = |QQ'I / d²

where K = 1/4π∈0, and

∈0 = 8.854 × 10⁻¹² C²/(N.m²) is the permittivity of free space.

Consider two point charges located on the x-axis:

one charge, q₁ = -18.5 nC, is located at

x₁ = -1.715m; the charge q₂ = 30.5 nC, is at the origin ( x₂=0 )

What is (Fnet3)x, the x-component of the net force exerted by these two charges on a third charge q₃ = 51.0 nC placed between q₁ and q₂ at x₃ = -1.085 m ?

Answer: (Fnet3)x = -3.3287 × 10⁻⁵ N

Explanation:

Given that;

Q₁ = -18.5 nC Q₃ = 51 nC Q₂ = 30.5 nC

x₁ = - 1.715m x₃ = - 1.085m x₂ = 0

Now

x - component of Net force on charge Q₃ is

(Fnet3)x = -K|Q₁I|Q₃I / r₁3² - -K|Q₂I|Q₃I / r₂3²

(Fnet3)x = -(9×10⁹)(51×10⁻⁹) [ 18.5 / ((-1.085 + 1.715)²) + (30.5 / (-1.085)² ] × 10⁻⁹

(Fnet3)x = -3.3287 × 10⁻⁵ N

Solar winds have an influence all the way to about 160 AU from the Sun. About how many kilometers is that?

Mumz [18]

Answer: A. 24,000,000,000 km

Explanation: An Astronomical Unit commonly abbreviated as AU is the average distance between Earth and the Sun and is about 150 million kilometers.

Astronomical unit is mainly used to measure distances within our solar system.

1 AU is equal to $150\times 10^6$ km

Thus 160 AU is equal to $\frac{150\times 10^6}{1}\times 160=24000\times 10^6km=24000000000km$

Why would a red apple appear black if you looked at it through a blue filter?

Grace [21]

<span>Because the reflected red light from the apple will not pass through the blue filter and since no light gets through it will appear black.</span>
