Consider the diatomic molecule oxygen o2 which is rotating in the xy plane about the z axis passing through its center, perpendicular to its length. the mass of each oxygen atom is 2.66 × 10^(-26) kg, and at room temperature, the average separation distance between the two oxygen atoms is 1.49 × 10^(-10) m (treat the atoms as point masses). if the angular speed of the molecule about the z axis is 4 × 10^(12) rad/s, what is its rotational kinetic energy? answer in units of j

When someone slams her books on a table the kinect energy is transferred into vibrations that travel to your ears as sound waves which statement describes the movement of those waves

Unpolarized light falls on two polarizer sheets whose transmission axes are at right angles. a third polarizer is placed between the first two so that its axis makes a 52-degree angle with the axis of the first polarizer. a) what fraction of the incident light intensity is transmitted through the first polaroid? b) what fraction of the incident light intensity is transmitted through the second polaroid? c) what is the angle of polarization of the light that enters the third polaroid? d) what fraction of the incident light intensity is transmitted through the third polaroid. e) what happens if the middle polaroid is removed?

Lacie kicks a football from ground level at a velocity of 13.9 m/s and at an angle of 25.0° to the ground. how long will the ball be in the air before it lands? how far will the football travel before it lands?
