.Answer;
Using Fmax=qVB
F=(1.6*10^-19 C)(5.860*10^6 m/s)(1.38 T)
ANS=1.29*10^-12 N
2. Using Amax=Fmax/ m
Amax =(1.29*10^-12 N) / (1.67*10^-27 kg)
ANS=1.93*10^15 m/s^2*
3. No, the acceleration wouldn't be the same. Since The magnitude of the electron is equal to that of the proton, but the direction would be in the opposite direction and also Since an electron has a smaller mass than a proton
B)
The speed of the cart changed because it stopped.

The index of refraction of the unknown material in which a ray of light is incident at 35° and refracted at 23° is 2.03
<h3>Snell's law</h3>
index of refraction (n) = Sine i / Sine r
n = Sine i / Sine r
Where
- i is the angle of incidence
- r is the angle of refraction
<h3>How to determine the refractive index </h3>
From the question given above, the following data were obtained:
- Index of refraction of oil (nₒ) = 1.38
- Angle of incidence (i) = 35°
- Angle of refraction (r) = 23°
- Index of refraction of unknown material (nᵣ) =?
nₒSine i = nᵣSine r
1.38 × Sine 35 = nᵣ × Sine 23
Divide both side by Sine 23
nᵣ = (1.38 × Sine 35) / Sine 23
nᵣ = 2.03
Thus, the index of refraction of the unknown material is 2.03

Answer:
F=2.47*10^{-10} N
Explanation:
The gravitational force is calculated by using

G: Cavendish constant = 6.67*10^{-12}Nm^2/kg^2
r=2.30cm=0.023m
M1=1.4kg
M2=14.0g=0.014kg
By replacing we have
F=2.47*10^{-10} N

Answer:
Explanation:
a )
Frequency n = 450 x 10⁶ .
20 light years = 20 x 9.461 x 10¹⁵m
Let power of source be P
Intensity at distance R = 
Substituting the given values
8.5 x 10⁻¹⁰ = 
P = 3822457 x 10²⁰ W.
b )
Half the power will be from electric and half will be from magnetic field.
Total power = 8.5 x 10⁻¹⁰ W
Half = 4.25 x 10⁻¹⁰ W .
power of electric field
= 
ε is permittivity , E₀ is amplitude of electric field , c is velocity of light .
Putting the values
4.25 x 10⁻¹⁰ = .5 x 8.85 x 10⁻¹² x E² x 3 x 10⁸
E₀² = .32 x 10⁻⁶
E₀ = .565 x 10⁻³ W / s .
