[Q]: Information: - Massachusetts ; officially the Commonwealth of Massachusetts, is the most populous state in the New England region of the northeastern United States. It is bordered by the Atlantic Ocean to the east, the states of Connecticut and Rhode Island to the south, New Hampshire and Vermont to the north, and New York to the west. The state is named for the Massachusett tribe, which once inhabited the area. The capital of Massachusetts and the most populous city in New England is Boston. Over 80% of Massachusetts' population lives in the Greater Boston metropolitan area, a region influential upon American history, academia, and industry. Originally dependent on agriculture, fishing and trade, Massachusetts was transformed into a manufacturing center during the Industrial Revolution. During the 20th century, Massachusetts' economy shifted from manufacturing to services. Modern Massachusetts is a global leader in biotechnology, engineering, higher education, finance, and maritime trade. - Albert Sands Southworth ( 1811 -- 1894 ) operated Southworth & Hawes daguerreotype studio with Josiah Johnson Hawes ( 1808 -- 1901 ) from 1843 to 1863 . - Josiah Johnson Hawes (18081901) was a photographer in Boston, Massachusetts.

input: Please answer the following: Information: - Melissa Joan Hart (born April 18, 1976) is an American actress, director, producer, singer, fashion designer, and businesswoman. She is known for her title roles in the sitcoms "Clarissa Explains It All" (19911994), "Sabrina the Teenage Witch" (19962003), and "Melissa & Joey" (20102015). - Silencing Mary , also released as Campus Justice , is a 1998 television film directed by Craig R. Baxley . The film was made to warn people about rape and popular teen actress Melissa Joan Hart was cast in the lead to draw a young audience . - Clarissa Explains It All is an American teen sitcom created by Mitchell Kriegman for Nickelodeon. In the series, Clarissa Darling, played by Melissa Joan Hart, is a teenager who addresses the audience directly to describe the things that are happening in her life, dealing with typical adolescent concerns such as school, boys, pimples, wearing her first training bra and an annoying little brother. - A television network is a telecommunications network for distribution of television program content, whereby a central operation provides programming to many television stations or pay television providers. Until the mid-1980s, television programming in most countries of the world was dominated by a small number of broadcast networks. Many early television networks (such as the BBC, NBC or CBC) evolved from earlier radio networks. - A television film (also known as a TV film; television movie; TV movie; telefilm; telemovie; made-for-television film; direct-to-TV film; movie of the week (MOTW or MOW); feature-length drama; single drama and original movie) is a feature-length motion picture that is produced for, and originally distributed by or to, a television network, in contrast to theatrical films, which are made explicitly for initial showing in movie theaters. Given the information, choose the subject and object entities that have the relation of 'distributor'.

Problem: Information: - A stellar magnetic field is a magnetic field generated by the motion of conductive plasma inside a star. This motion is created through convection, which is a form of energy transport involving the physical movement of material. A localized magnetic field exerts a force on the plasma, effectively increasing the pressure without a comparable gain in density. As a result, the magnetized region rises relative to the remainder of the plasma, until it reaches the star's photosphere. This creates starspots on the surface, and the related phenomenon of coronal loops. - The barycenter (or barycentre; from the Ancient Greek "heavy" + "centre") is the center of mass of two or more bodies that are orbiting each other, or the point around which they both orbit. It is an important concept in fields such as astronomy and astrophysics. The distance from a body's center of mass to the barycenter can be calculated as a simple two-body problem. - Magnetic braking is a theory explaining the loss of stellar angular momentum due to material getting captured by the stellar magnetic field and thrown out at great distance from the surface of the star . It plays an important role in the evolution of binary star systems . - In physics, an orbit is the gravitationally curved path of an object around a point in space, for example the orbit of a planet about a star or a natural satellite around a planet. Normally, orbit refers to a regularly repeating path around a body, although it may occasionally be used for a non recurring trajectory or a path around a point in space. To a close approximation, planets and satellites follow elliptical orbits, with the central mass being orbited at a focal point of the ellipse, as described by Kepler's laws of planetary motion. - In classical mechanics, linear momentum, translational momentum, or simply momentum (pl. momenta; SI unit kgm/s) is the product of the mass and velocity of an object, quantified in kilogram-meters per second. It is dimensionally equivalent to impulse, the product of force and time, quantified in newton-seconds. Newton's second law of motion states that the change in linear momentum of a body is equal to the net impulse acting on it. For example, a heavy truck moving rapidly has a large momentum, and it takes a large or prolonged force to get the truck up to this speed, and would take a similarly large or prolonged force to bring it to a stop. If the truck were lighter, or moving more slowly, then it would have less momentum and therefore require less impulse to start or stop. - A binary star is a star system consisting of two stars orbiting around their common barycenter. Systems of two or more stars are called "multiple star systems". These systems, especially when more distant, often appear to the unaided eye as a single point of light, and are then revealed as multiple by other means. Research over the last two centuries suggests that half or more of visible stars are part of multiple star systems. - In physics, angular momentum (rarely, moment of momentum or rotational momentum) is the rotational analog of linear momentum. It is an important quantity in physics because it is a conserved quantity the angular momentum of a system remains constant unless acted on by an external torque. - Physics (from , from "phusis" "nature") is the natural science that involves the study of matter and its motion and behavior through space and time, along with related concepts such as energy and force. One of the most fundamental scientific disciplines, the main goal of physics is to understand how the universe behaves.
