SOLUTION:

Question 4 -

- 2x + 5 = - 13 + x

- 2x - x = - 13 - 5

- 3x = - 18

x = - 18 / - 3

x = 18 / 3

x = 6

Question 6 -

2x + 7 = - 2 - x

2x + x = - 2 - 7

3x = - 9

x = - 9 / 3

x = - 3

Question 8 -

2x + 12 = - 6 - x

2x + x = - 6 - 12

3x = - 18

x = - 18 / 3

x = - 6

Hope this helps! :)
Have a lovely day! <3

drek231 [11]

Answer:The rate of ejection of photoelectrons will increase

Explanation:

If the frequency of incident monochromatic light is held constant and its intensity is increased, the rate of ejection of photoelectrons from the metal surface increases with increase in intensity of the monochromatic light. More current flows due to more ejection of photoelectrons.

Suppose a rectangular piece of aluminum has a length D, and its square cross section has the dimensions W XW, where D (W x W) to
Ludmilka [50]

Answer:

R₂ / R₁ = D / L

Explanation:

The resistance of a metal is

        R = ρ L / A

Where ρ is the resistivity of aluminum, L is the length of the resistance and A its cross section

We apply this formal to both configurations

Small face measurements (W W)

The length is

         L = W

Area  

         A = W W = W²

        R₁ = ρ W / W² = ρ / W

Large face measurements (D L)

       Length L = D= 2W

       Area     A = W L

     R₂ = ρ D / WL = ρ 2W / W L = 2 ρ/L

The relationship is

    R₂ / R₁ = 2W²/L
