Answer:kinetic Heat

Explanation:

kinetic Heat

Heat is the energy in transit i.e. when the kinetic energy of one body is transfer from one body to another body it is called heat.

When a body is heated its kinetic energy changes and as a result its temperature increases and transfer of this energy is called kinetic heat i.e. Heat in movement.

A circuit consists of a 171- resistor and a 0.158-H inductor. These two elements are connected in series across a generator that
kotykmax [81]

Answer:

a ) I= 1.635-i0.0021 b) ∅=   -0.074

Explanation:

a) reactive impeadance= 2πfL

                                 =2(3.14)(147)(0.158)

                                 =145.86 Ω

Z= 171+j145.86

I=V/Z

I=278/(171+j145.86)

I= 1.635-i0.0021

b) ∅=inv.tan (-0.0021/1.635)

 ∅=-0.074

Part 1- An ideal gas, initially at a volume of 1.71429 L and pressure of 7 kPa, undergoes isothermal expansion until its volume
Musya8 [376]

Part 1- The work done by the gas during this process will be 5.65 ×10⁻³ kJ.

Part 2-The heat added to the gas during this process will be 5.65 ×10×10⁻³ kJ.

<h3>What is work done by the gas?</h3>

Work is the product of pressure p and volumes V during a volume change for such a gas. The work seems to be the area under the curve that indicates how the state changes.

The work done under the isothermal process is;

\rm W= P_1V_1 log_e(\frac{P_1}{P_2} )\\\\ W= 7 \times 1.71429  \times 10^{-3} log_e(\frac{7 }{2} )\\\\\ W= 0.0044 \  kJ

For the isothermal process;

ΔU=0

\rm \triangle Q = \triangle E + \triangle W \\\\ Q =  0 + 5.65 \times 10^{-3}\\\\ Q = 5.65 \TIMES 10^{-3} \ kJ

Hence, the work done, and the heat added by the gas during this process will be 5.65 ×10⁻³ kJ and 5.65 ×10×10⁻³ kJ respectively.

You are a nurse in a hospital. You are told to move a patient through three corridors each measuring 14.33 meters. Because of fr
dimulka [17.4K]

Work done by force is given by formula

W = F.d

now here work done against friction is given so force of friction here is

F_f = 848 N

It moved by three corridors with each measures

d = 14.33 m

so total distance will be

s = 14.33 \times 3 = 43 m

now from above formula of work done we will say

W = 848 \times 43

W = 36464 J

so above is the work done to move three corridors
