the rate of heat flow through a slab does not depend on which of the following?
a- the Temperature dependent between opposite faces of the slab
b- the thermal conductivity of the slab
c- the thickness of the slab
d- the cross-sectional areas of the slab
e- the specific heat of the slab
also I have one problem if you can help me
a caller produces a sound with an intensity level of 108 dB. how many callers requires to reach the own level of 120 dB?
-- A person with a mass of 81 kg and a volume of .089m^3 floats quietly in water. a) what is the volume of the person that is above water? b) if an upward force F is applied to the person by a friend, the volume of the person above water increases by .0018 m^3. find the force F.
Thank you so much. please help me with these questions.
