The increase in temperature that will result if 225.0 g of copper absorbs 5000 J of heat energy is 57.72°C.

<h3>How to calculate temperature change?</h3>

The temperature change of a substance can be calculated using the following formula:

Q = m × c × ∆T

Where;

  • Q = quantity of heat absorbed or released
  • m = mass of substance
  • c = specific heat capacity
  • ∆T = change in temperature

5000 = 225 × 0.385 × ∆T

5000 = 86.63∆T

∆T = 5000/86.63

∆T = 57.72°C

Therefore, the increase in temperature that will result if 225.0 g of copper absorbs 5000 J of heat energy is 57.72°C.

What is the energy dissipated as a function of time in a circular loop of N turns of wire having a radius of r0 and a resistance
Snezhnost [94]

Explanation:

Let N be the number of turns in a circular loop having a radius of r₀ and a resistance R. The magnetic field is given by :

B(t)=B_oe^{-\dfrac{t}{\tau}}

The induced emf in the circular coil is given by :

\epsilon=\dfrac{-d\phi}{dt}

Where

\phi=BA

\epsilon=N\dfrac{-d(BA)}{dt}

\epsilon=NAB_o\dfrac{-d(e^{-\dfrac{t}{\tau}})}{dt}

\epsilon=\dfrac{NAB_o}{\tau}e^{-t/\tau}

Power dissipated is given by :

P=\dfrac{\epsilon^2}{R}

P=\dfrac{(\dfrac{NAB_o}{\tau}e^{-t/\tau})^2}{R}

P=(\dfrac{NAB_o}{\tau})^2\dfrac{e^{-2t/\tau}}{R}

Energy dissipated in the circuit is given by :

E=\int\limits^T_0 {P.dt}

E=\int\limits^T_0 {(\dfrac{NAB_o}{\tau})^2\dfrac{e^{-2t/\tau}}{R}.dt}

E=\dfrac{1}{R}(\dfrac{NAB_o}{\tau})^2\int\limits^T_0 {e^{-2t/\tau}.dt}

E=\dfrac{(N\pi r_o^2B_o^2)^2}{2R}{\tau(e^{2t/\tau}-1)}{}

Hence, this is the required solution.

It is easier to add vectors together if we split them into what? A. Sizes B. Components C. Quadrants D. Lines
jonny [76]

Answer:

<h2> B. Components</h2>

Explanation:

Splitting vectors into components makes it easier to perform operations on them, typically categorizing vectors into horizontal and vertical components which are the two components makes it very easy to perform operations, since they are similar terms and operations cab be done easily

You are designing a thin transparent reflective coating for the front surface of a sheet of glass. The index of refraction of th
galben [10]

Answer:

The index of refraction of the coating  is 1.32.

Explanation:

Given that,

Index of refraction of the glass = 1.52

Thickness = 104 nm

Length = 550 nm

We need to calculate the index of refraction of the coating

Using formula of index

n = \dfrac{L}{4t}

Where, L = length

t = thickness

Put the value into the formula

n=\dfrac{550}{4\times104}

n=1.32

Hence, The index of refraction of the coating  is 1.32.

Two bodies, with heat capacitiesC1andC2(assumed independent oftemperature) and initial temperatureT1andT2, respectively, are pla
Anna007 [38]

Answer:

Tբ = (C₁T₁ + C₂T₂)/(C₁ + C₂) = (C₁T₁)/(C₁ + C₂) + (C₂T₂)/(C₁ + C₂)

Explanation:

Let's Assume that T₁ > T₂, this means that, T₁ > Tբ > T₂

The zeroth law of thermodynamics explains that two bodies in thermal equilibrium will eventually end up with the same final body temperature.

Heat lost by body 1 = Heat gained by body 2

C₁ (T₁ - Tբ) = C₂ (Tբ - T₂)

C₁T₁ - C₁Tբ = C₂Tբ - C₂T₂

C₁Tբ + C₂Tբ = C₁T₁ + C₂T₂

Tբ(C₁ + C₂) = C₁T₁ + C₂T₂

Tբ = (C₁T₁ + C₂T₂)/(C₁ + C₂)

Tբ = (C₁T₁)/(C₁ + C₂) + (C₂T₂)/(C₁ + C₂)
