The heat required to raise the temperature of the copper is \boxed{1252.6\,{\text{cal}}}.

Further Explanation:

Given:

The mass of the copper is 0.368\,{\text{kg}}.

The specific heat capacity of copper is 0.0920\,\text{cal/g}\cdot^\circ\text{C} .

Concept:

The specific heat capacity of a particular substance is the amount of energy required to raise the temperature of unit mass of the substance by 1\,^\circ {\text{C}}.

The change I temperature required to heat the copper is given as.

\Delta T = {T_f} - {T_i}  

Substitute the final and initial values of temperature.

\begin{aligned}\Delta T &= 60 - 23\,^\circ {\text{C}} \\&= {\text{37}}\,^\circ {\text{C}} \\\end{aligned}  

The expression for the amount of heat required to raise the temperature of the copper is.

 \boxed{Q = mC\Delta T}

Here, Q is the amount of heat required, m is the mass of the substance, C is the specific heat capacity and \Delta T is the change in temperature required.

Substitute the values in above expression.

\begin{aligned}Q&=368\,\text{g}\times(0.0920\,\text{cal/g}\cdot{^\circ\text{C}})\times(37\,{^\circ}\text{C})\\&=1252.6\,\text{cal}\end{aligned}  

Thus, the amount of heat required to raise the temperature of the copper from 23\,{\text{^\circ C}} to 60\,{\text{^\circ C}} is \boxed{1252.6\,{\text{cal}}}.

The change in temperature here corresponds to a sensible heat. The amount of energy required can be calculated by multiplying the specific heat capacity, the amount of the substance and the corresponding change in temperature.

Heat required = mCΔT
Heat required = 0.368 kg (0.0920 cal/g°C) (60 - 23)°C
Heat required = 1.25 cal

How much conventional current must you run in a solenoid with radius = 0.05 m and length = 0.39 m to produce a magnetic field in
Ugo [173]

Answer:

Explanation:

radius of the solenoid, r = 0.05 m

length of the solenoid, l = 0.39 m

Magnetic field of the solenoid, B = 2 x 10^-5 T

Number of turns, N = 200

The magnetic field of the solenoid is given by

B=\mu _{0}ni

where, i be the current and n be the number of turns per unit length

n = N / l = 200 / 0.39 = 512.8

2\times 10^{-5}=4 \times 3.14\times 10^{-7}\times 512.8\times i

i = 0.031 A
