Q1. A 4.00 X 100 g glass coffee cup is 22.0 C at room temperature. It is next plunged into hot dishwater at the temperature of 80.0 C. If the temperature of the cup reaches that of the dishwater, how much heat does the cup absorb? Suppose that the mass of the dishwater is large as much as necessary so that its temperature does not change appreciably.
Q2. The motion sensor used in this experiment has the minimum range of 0.16m and a maximum range of 11.0m. Explain in theoretical terms, how you could have increased or lowered the range of the distance covered by the motion sensor.
