Answer:
Convection and Radiation mechanisms carry most of the heat
Explanation:
This is because Convection proceeds strongy as heated air rises from the hot element while Radiation is also strong, although the material of the cooking pots will how effective it is.
Answer:
conservative
Explanation:
Nonconservative force is the force that depends on a path, however conservative does not depend on a path and it is not associated with the potential energy. When the work is done by an unconservative force, mechanical energy is added or removed. Friction is the best example for a non-conservative force. When these non-conservative forces are acting, the mechanical energy changes but these are not preserved.
hope this helped!
Answer:
K= 1/2 mv^2
m= 2K/v^2= 2250/ 225= 10 Kg
Answer:
Babies often struggle to go to sleep sometimes warm milk and sooting sounds help babies sleep
Explanation:
Answer:
Explanation:
As per ideal gas equation we know that
PV = nRT
here we know that
now we have
now for other case at zero gauge pressure we have
we have now
now the difference in internal energy of air is given as
