Calculate the point along a line joining the centre of earth and moon where there is no gravitational force. (Given: mass of Earth = 6×10^24 kg, mass of Moon = 7.4×10^22 kg, distance between centre of earth and moon = 3.8×10^8 m).

Herbivores, carnivores, and omnivores are all types a. decomposers b. producers c. consumers d. biomes

What is the momentum of a 2 kg object moving at 15 meters per second

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?
