Q1. Water at a temperature of 85f, exhibits which of these physical properties
a. has no definite shape
b. has no definite volume
c. has particles that do not move
d. has particles that move independently
Q2. A motor keep a Ferris wheel (with moment of inertia 8.29 × 107 kg • m2) rotating at 6.5 rev/hr. When the motor is turned off, the wheel slows down (since friction) to5.2 rev/hr in 27 s.
What was the power of the motor that kept the wheel rotating at 6.5 rev/hr in spite of friction?
Radioactive decay of granite and other rocks in the Earth's interior provides sufficient energy to keep the interior molten, heat lava, and supply warmth to natural hot springs.
A 770 kg car moving at 21 m/s brakes to a stop. The brakes contain about 15 kg of iron, which absorbs the energy. What is the increase in temperature of the brakes.
