AYUDA POR FAVOR ES MUY URGENTE Se calienta una esfera sólida de aluminio de 1.5kg que se encuentra inicialmente a 10°C, aplicándole 650kJ
de energía calorífica. ¿Qué volumen tendrá la esfera después de calentarse?

Awheel rotates without friction about a stationary horizontal axis at the center of the wheel. a constant tangential force equal to 82.0 n is applied to the rim of the wheel. the wheel has radius 0.150 m . starting from rest, the wheel has an angular speed of 12.8 rev/s after 3.88 s. what is the moment of inertia of the wheel?

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?

Which lists the pairs of plates in order from least to greatest in terms of the work done to move the electron?
