A calorimeter contains 1.0 kg of water (specific heat = 4,184 J/(kg.°C)). An object
with a mass of 4.23 kg is added to the
water. If the water temperature increases
by 3.0°C and the temperature of the
object decreases by 1.0°C, what is the
specific heat of the object?

Aturntable a is built into a stage for use in a theatrical production. it is observed during a rehearsal that a trunk b starts to slide on the turntable 10 s after the turntable begins to rotate. knowing that the trunk undergoes a constant tangential acceleration of 0.31 m/s2, determine the coefficient of static friction between the trunk and the turntable.
