Response:

U = 12,205.5 J

Clarification:

To determine the internal energy of an ideal gas, use the following equation:

U=\frac{3}{2}nRT        (1)

U: internal energy

R: ideal gas constant = 8.135 J(mol.K)

n: number of moles = 10 mol

T: the temperature of the gas = 100K

Substituting the parameter values into equation (1):

U=\frac{3}{2}(10mol)(8.135\frac{J}{mol.K})(100K)=12,205.5J

The overall internal energy for 10 moles of Oxygen at 100K is 12,205.5 J

Answer with Explanation:

Concepts and reasoning

The principle for addressing this question is that a capacitor in an RC circuit allows current to flow until fully charged. Once charged, it prevents any further current from moving through. Conversely, the situation is different with an inductor in an RL circuit. In accordance with Faraday's law, an inductor generates an electromagnetic force to counteract the applied voltage, but when no change in flux occurs, it behaves akin to a regular wire as if the inductor is absent.

In the accompanying diagram, a resistor is connected in series with a capacitor.

As we observe

the voltage across both the capacitor and the source.

Voltage across a resistor in an RL circuit.V_{R}=V_S\left ( e^{-\frac{t}{RC}} \right )

V_{R}=V_S\left (1- e^{-\frac{Rt}{L}} \right )

Softa [3030]
It shows a situation where a proton moves perpendicular to a magnetic field of 0.025 tesla. The force acting on the proton has a magnitude of 1.8 × 10⁻¹⁴ newtons, and we need to determine the speed of the proton given q = 1.6 × 10⁻¹⁹ coulombs.

A 100-watt light bulb radiates energy at a rate of 100 J/s. (The watt, a unit of power or energy over time, is defined as 1 J/s.
Keith_Richards [3271]

Answer:

2.64\times 10^{20} The number of photons emitted each second is

Explanation:

Let 'n' stand for the quantity of photons released by the bulb.

Provided Information:

The bulb radiates energy at a rate of 100 J per second (E).

Wavelength of emitted light is (λ) = 525 nm = 525\times 10^{-9}\ m

The energy of a photon is calculated by:

Where,

E_0=\frac{hc}{\lambda}

Now, if we have 'n' photons, the total energy is equivalent to the energy of a single photon multiplied by the count of photons. Thus,

h\to Planck's\ constant=6.626\times 10^{-34}\ Js\\\\c\to Speed\ of \ light=3\times 10^{8}\ m/s

To express in terms of 'n', we find:

E=nE_0\\\\E=\frac{nhc}{\lambda}

Insert the provided values and solve for 'n'. The resulting calculation yields

n=\frac{E\lambda}{hc}

Consequently,

photons are discharged every second.n=\frac{100\times 525\times 10^{-9}}{6.626\times 10^{-34}\times 3\times 10^{8}}\\\\n=2.64\times 10^{20}

2.64\times 10^{20}
