The star HD 12661 is located at a distance of 121 light years, on the border of the constellation Aries near Triangulum. The pla
net's period is 250 days, with an average distance from its star of 0.80 AU. (One astronomical unit, or AU, is 93 million miles, the distance from the Earth to the Sun.) The lower limit on its mass is 2.8 Jupiter masses. The star HD 92788 is located 104 light years from Earth in the constellation Sextans. The planet's period is 341.7 days, and it orbits at an average distance of 0.98 AU. Its mass is at least 3.7 Jupiter masses. The star HD 38529 is 137 light years away, in the constellation Orion. The planet's period is 14.3 days; its average distance from the star is 0.13 AU. The lower limit on its mass is 0.77 Jupiter masses. a) Find the mass of the three stars listed above. b) Determine how many times more or less massive these stars are than the Sun. c) Explain why the second of these three planets is the most interesting to planetary scientists.
c) I feel it is interesting because of the planet's period that is 341.7 days, and it orbits at an average distance of o.98AU, and the mass of the star is almost very identical to the mass of our sun.

Globalization is the process of transformation of people, money, and material from local to the global worldwide level. It's the integration and interaction of business and customers across or beyond borders.
Economic globalization includes the goods, services, technology, and capital and data to the expanding global markets where activities of exchange of goods and services take place.
Currently FDI, export and import and trade blocs all have risen due to technological processes that make the single market economy.
The cultural globalization refers to the transfer of an idea, meanings and moral values around the world in such a way that extends the social relations. Technology has made possible the cross-culture communication and everyone has benefited from it.
Thus globalization is good as long as it keeps the world connected and eliminating gender disparities.
Thermal energy usually flows from an object that has a higher temperature to an object with a lower temperature. Since the whales are from Florida’s warmer waters and they can generate their own body heat since they are warm-blooded, more thermal energy would move from the whale into its environment in cooler waters.
