A 2.33x 107 g mass of aluminum at 100.0°C, is placed in a glass beaker containing 3.00 x 107 g of water at 10.0°C. Assume no heat loss to the surroundings. The final temperature of the mixture is 25°C. What is the specific heat of the aluminum?

Aperson stands on a platform, initially at rest, that can rotate freely without friction. the moment of inertia of the person plus the platform is ip. the person holds a spinning bicycle wheel with its axis horizontal. the wheel has moment of inertia iw and angular velocity ωw. take the ωw direction counterclockwise when viewed from above. part a what will be the angular velocity ωp of the platform if the person moves the axis of the wheel so that it points vertically upward?

Atemperature inversion can cause a warm air mass to move over a colder air mass. this traps the colder air mass and prevents surface air from rising. this may result in which of these? a) smog b) acid rain c) freezing rain d) a thunderstorm
