Answer:
a. 80 J/cell b. 1.02 × 10²¹ W/m² c. 8.77 × 10¹¹ V/m d. 2.92 × 10³ T
Explanation:
a. We know that energy E = Pt where P = power and t = time
The total energy delivered to all the 100 cells is E = average power × time
average power = 2 × 10¹² W and time = 4 ns = 4 × 10⁻⁹ s
E = 2 × 10¹² W × 4 × 10⁻⁹ s = 8 × 10³ J
The energy per cell E₁ = E/100 = 8 × 10³ J/100 = 80 J/cell
b. Intensity, I = P/A where P = power per cell = 2 × 10¹² W/100 = 2 × 10¹⁰ W and A = area = πr². Since the cell is modeled as a disk of diameter d = 5.0μm, r = d/2 = 5.0 μm/2 = 2.5 μm = 2.5 × 10⁻⁶ m
I = P/A = P/πr² = 2 × 10¹⁰ W/π(2.5 × 10⁻⁶ m)² = 1.02 × 10²¹ W/m²
c. The intensity I = E²/2cμ₀ where E = maximum value of electric field, c = speed of light = 3 × 10⁸ m/s and μ₀ = 4π × 10⁻⁷ H/m
E = √(I2cμ₀) = √(2 × 1.02 × 10²¹ W/m² × 3 × 10⁸ m/s × 4π × 10⁻⁷ H/m) = 8.77 × 10¹¹ V/m
The maximum magnetic field B is gotten from E/B = c
B = E/c = 8.77 × 10¹¹ V/m/3 × 10⁸ m/s = 2.92 × 10³ T
Answer:
The juice contains sugars, plant pigments, and other chemicals dissolved in water. This is a solution. The pieces of orange pulp will rise to the top or settle to the bottom of the juice if it is allowed to sit. The pieces of pulp mixed with the juice form a suspension.
Explanation:
In chemistry, a suspension is a heterogeneous mixture containingsolid particles that are sufficiently large for sedimentation. Usually they must be larger than one micrometer. A Suspension is a heterogeneous mixture in which the soluteparticles do not dissolve but get suspended throughout the bulk of the medium.a solution is a homogeneous mixture composed of two or moresubstances. In such a mixture, a solute is a substance dissolved in another substance, known asa solvent.. it is considered a solution andsuspension because the orange juice mix with water while the pulp did not andretained as solid
