According to the lecture, why are transfer effects from cognitive training often difficult to achieve?

How much mass should be attached to a vertical ideal spring having a spring constant (force constant) of 39.5 N/m so that it will oscillate at 1.00 Hz?

A solid concrete wall has dimensions [L] m x[b] m and is [d] cm thick. The thermal conductivity of the concrete is 1.3 W/m ∙ K, and it separates a basement from the ground outside. The inner surface of the wall is at [p]°C, and the outside surface is at [q]°C. How much heat flows through the wall every [t] minutes?

When the first law of thermodynamics, delta Q = delta U + delta W , is taken through an adiabatic process( delta = change)

A [m] kg copper bar is put into a smelter for melting. The initial temperature of the copper is [a] K. How much heat must the smelter produce to completely melt the copper bar? The specific heat for copper is 386 J/kg∙K, the heat of fusion for copper is 205,000 J/kg, and its melting point is 1357 K.

What is the Coefficient of Performance of a refrigerator that works between [x]0 Cand [y]0 C ?

What is the entropy change of [m] g of water when it changes from  liquid to steam at its usual boiling point ?LV = 2.26 MJ/kg.

If a string fixed at both ends resonates in its fundamental mode with a frequency of 150 Hz, at which of the following frequencies will it  not resonate? 

Calculate the net change in entropy when 3 kg of hot water at 900C is mixed with 1 kg of cold water at 100C.  The specific heat of water is 4186 J/kg/K. ( Show your work in the space provided here)

A block of mass  m sits at rest on a rough inclined ramp that makes an angle  θ with the horizontal. What must be true about normal force  F on the block due to the ramp?
