Liquid 1 reacts with Liquid 2, producing a solid and a gas. Using this scenario, which supports the law of conservation of mass?
ОООО
mass of Liquid 1 + mass of solid = mass of Liquid 2 + mass of gas
mass of Liquid 1 - mass of solid = mass of Liquid 2 - mass of gas
O mass of Liquid 1 - mass of Liquid 2 = mass solid + mass of gas
mass of Liquid 1 + mass of Liquid 2 = mass of solid + mass of gas

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?
