Kinetic energy is a result of mass in motion at a certain velocity.
<span>1 Joule = 1 kg • (m/s)<span>2
</span></span>the force as a function of mass of the object.
The answer to the given question above is option C. In a classical conditioning experiment, you ring a bell but no longer provide dinner to your subject, a beagle and at last, the CS no longer evokes the CR so therefore, <span> you've accomplished behavioral EXTINCTION. Hope this helps.</span>
Explanation :
Conduction : Conduction is the transfer of heat due to collision between the molecules in the substance.
It is the way of energy transferred in the solid.
Convection : When air is heated and then travels away from the source that means air caries the heat along.
it is called convection.
It is the way of energy transferred in the air and liquid.
Radiation : radiation generate from the emission of electromagnetic wave.
electromagnetic wave carry the energy away from the source which is emitting the radiation.
It is the way of energy transferred in the vacuum.
Answer:
Explanation:
a ) Entropy change dS = dQ/T
= mcdT /T
Integrating both sides
S₂ - S₁ = - mclnT₂ /T₁
= - .5 X 4200 ln (85+273) /( 20 + 273 )
.5 X 4200 ln 358/ 293
= - 417.6 J/K
Entropy change will be negative as heat is lost by the system .
b ) Sine there is no change in the temperature of air , This heat will enter air at temperature ( 20+ 273) K = 293 K
Heat entering air
= .5 x 4200 x 65
= 136500 J
Change in entropy
136500 / 293 ( room temperature is constant at 293k
= + 465.87 J/K
Entropy change will be positive as heat is gained by the system .
Total change in the entropy of the system (tea + air )
= +465.87 - 417.6
= 48.27 J/K
Entropy change will be negative as heat is lost by the system .
Answer:
Elements in a period share the highest unexcited electron energy level. There are more elements in some periods than others because the number of elements is determined by the number of electrons allowed in each energy sub-level.
