**Solar Sail Problem**Consider a large solar sail in the form of a square with sides of length \( \ell = 100 \ \text{m} \) that is fabricated from a stiff, completely transparent plastic sheet. The plastic sheet is bent back and forth along a series of equally spaced lines parallel to one edge, forming a "concertina-like" structure as shown in the figure. The distance, \( d \), between the bends is \( d \ll \ell \) and the angle at each bend is \( 90^\circ \).a) If the front face of the sail has a highly reflective coating and the sail is illuminated normally with radiation of intensity \( I = 1.3 \ \text{kW m}^{-2} \), determine the total radiative force experienced by the sail.b) If over time the reflective coating degrades such that it only reflects 50% of the incident radiation, with the remaining 50% transmitting through the plastic sheet, what is the radiative force now experienced by the sail?c) How is the answer to part b) changed if the plastic sheet has also degraded such that it is no longer completely transparent but absorbs 30% of the radiation attempting to pass through it?**Note:** All dimensions in this problem are significantly larger than the wavelength of the incident radiation.**Diagram Explanation**The diagram depicts a zigzag pattern representing how the plastic sheet is folded. The vertical lines with arrows show the direction of the incident radiation. It highlights the concertina-like structure and labels the distance between the folds as \( d \) and the length of each side of the square as \( \ell = 100 \ \text{m} \).

In the methane molecule, CH4, each hydrogen atom is at the corner of a regular tetrahedron with the carbon atom at the center. If one of the C-H is in the direction of A=î +î+R and an adjacent C-H bond is at the direction B=î-Î-R. results to an angular bond of approximately 109° for a static frozen molecule. However, the molecule we can encounter everyday continuously vibrates and interact with the surrounding causing its bond vector to vary slightly. According to a new spectroscopy analysis, the adjacent bond vectors was found to be A = 1.06i + 0.8j + 1.03k B = 1i + -0.92j + -0.95k What is the angle (in degrees) between the bonds based on this new data?

A particle of mass m is suspended from a support by a light string of length which passes through a small hole below the support (see diagram below). The particle moves in a vertical plane with the string taut. The support moves vertically and its upward displacement (measured from the ring) is given by a function z = h(t). The effect of this motion is that the string-particle system behaves like a simple pendulum whose length varies in time.
