A 300 g glass thermometer initially at 20 ◦C
is put into 297 cm3
of hot water at 83 ◦C.
Find the final temperature of the thermometer, assuming no heat flows to the
surroundings. The specific heat of glass is
0.2 cal/g ·
◦ C and of water 1 cal/g ·
◦ C.

Astone is thrown with a speed v0 and returns to earth, as the drawing shows. ignore friction and air resistance, and consider the initial and final locations of the stone. which one of the following correctly describes the change δpe in the gravitational potential energy and the change δke in the kinetic energy of the stone as it moves from its initial to its final location? options a.δpe = 0 j and δke = 0 j b.δpe is positive and δke is negative c.δpe = 0 j and δke is positive d.δpe is negative and δke is positive e.δpe = 0 j and δke is negative
