A 0.150 kg frame, when suspended from a coil spring, stretches the spring 0.0400 m. A 0.200 kg lump of putty is dropped from rest onto the frame from a height of 30.0 cm (Fig. P8.78). Find the maximum distance the frame moves downward from its initial equilibrium position.

layer a is the exosphere and layer b is the thermosphere.   is the answer i think but i hope this .

if the thermos has a vacuum innner, then heat through conv currents and conduction are reduced = vacuum flask

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
