A repelling force occurs between two charged objects when the charges are of Equal magnitude. Equal magnitude. a Unequal magnitu
Ahat [919]

Answer:

c Like/same signs

Explanation:

A repelling force occurs between two or more charged objects with the charges are of like or same sign.

  • According to Coulombs law, like charges repel on another, unlike charges attracts on another.
  • If a positive charge comes into the vicinity of another positive charge, there will be repulsion.
  • When oppositely charge species are brought near each other, there is an attraction.

Therefore, repulsion occurs when like charges are brought close to each other.

One anthem of silicon can properly be combined in a compound with
Darya [45]
One atom of silicon can properly be combined in a compound withtwo atoms of oxygen to produce silicon dioxide because silicon is very similar to carbon, as it is in the same group as carbon is in, therefore, it is able to make four bonds.
Moreover, Silicon has 4 valence electrons. In order to form an ionic bond, silicon<span> would have to gain or lose 4 electrons.</span>

Consider a 400 nm thick film of water (n-1.33) on plastic (-1.9). Visible light is incident. on the film firom air. (25 pts) Ske
Gnoma [55]

Answer:

Explanation:

For constructive interference in thin films by reflected light , the condition is

Path difference =  2μd = odd multiple of λ / 2

Where μ is refractive index of water , d is thickness of water medium and λ

is wavelength of light

λ = 4μd or 4μd / 3 or 4μd / 5

= 4 x 1.33 x 400 nm = 2128 nm

or 2128 /3 = 709.33 nm

or 2128 /5 = 425.6 nm

For destructive interference ( dim reflection )

2μd = multiple of λ = λ or 2λ or 3λ

2 x 1.33 x 400 nm =1064

or 1064 x 2 = 2128 nm

or 1064 x 3 = 3192 nm.

A 2.3 m -long wire carries a current of 8.6 A and is immersed within a uniform magnetic field B⃗ . When this wire lies along the
Volgvan

Answer:

Explanation:

Given that :

The current I = 8.6 A

The length vector L = 2.3 m i

The force vector is = -2.0 j N

When L = 2.3 m i ; the

Force vector F = (2.0 i - 4.8 k) N

Compute the components of the magnetic field as follows:

F = I(L*B)

Replacing 8.6 A for I ; -2.0 j N for F & 2.3 m i for L

-2.0 j N = (8.6 A) (2.3 m i *(B_xi + B_yj+B_zk)

-2.0 j N = 19.78B_z \ and  \ 0 = 19.78B_y

B_z = -0.1011 T  \ and \ B_y = 0

However in y direction ; we have :

(2.0 i - 4.8 k) = 8,6 A (2.3 mi*(B_xi+B_yj+B_zk)

- 2.0 = 19.78 B_z \ and \ -4.8 = 19.78 B_x

B_z = -0.1011 T \ and \ B_x = -0.2427T

Hence, the component of magnetic field is as follows:

B_x = -.02427T \ ; B_y = 0 T \  ; B_z =  - 0.1011 T)
