Answer:

a.

Explanation:

The sum of the maximum voltages across each element in a series RLC circuit is usually greater than the maximum applied voltage because voltages are added by vector addition.

Kirchhoff's loop rule states that the algebraic sum of potential differences, as well as the voltage supplied by the voltage sources and resistances, in any loop must be equal to zero.

In a series RLCcircuit, the voltages are not added by scalar addition but by vector addition.

Kirchhoff's loop rule is not violated since the voltages across different elements in the circuit are not at their maximum values.

Therefore, the sum of the maximum voltages across each element in a series RLC circuit is usually greater than the maximum applied voltage because voltages are added by vector addition.

From the information provided and the calculations, the energy of the drop is 1.51 eV

The Rydberg formula is used to obtain the energy of a photon or the wavelength of a photon.

Thus;

1/λ = 1.097 * 10^7 (1/3^2 - 1/5^2)

1/λ = 1.097 * 10^7(0.11 - 0.04)

λ = 1.3 * 10^-6 m

Since;

E = hc/λ

E = 6.6 * 10^-34 * 3 * 10^8/1.3 * 10^-6

The vector with components x = -44 m and y = -59 m has a direction of approximately 52.16 degrees counterclockwise from the positive x-axis.

The direction of a vector with components x = -44 m and y = -59 m can be determined using trigonometry.  In this case, we have:

x-component (x) = -44 m

y-component (y) = -59 m

We can use the inverse tangent function to find the angle.

The direction angle (θ) can be calculated as:

θ = arctan(y / x)

θ = arctan((-59 m) / (-44 m))

Calculating this expression:

θ ≈ arctan(1.341)

To find the actual angle, we can use a calculator or table to determine the inverse tangent of 1.341.

θ ≈ 52.16 degrees

Therefore, the direction of the vector is approximately 52.16 degrees in the counterclockwise direction from the positive x-axis.

Power = 2500 W

Substitute the values into the formula

Power × time = mass × specific heat

2500 × time = 1. 5 × 4000000

Make 'time' the subject

time = 1. 5 × 4000000 ÷ 2500 = 6000000 ÷ 2500 = 2400 seconds
