An astronomer observes two ordinary stars. The first one turns out to be twice as hot as the second. This means that the first o
ne radiates:O twice as much energy as the second O roughly the same amount of energy as the second O half as much energy as the second O about 16 times the energy of the second O this problem cannot be solved with just the information we were given
This can be explained thanks to the Stefan-Boltzmann law, which relates temperature directly to the amount of energy released by an object.
With this law in mind, the total energy radiated during 1 second from 1 square meter of any object, equals <em>a constant </em>(5.670374419 × 10−8 watt per meter2 per K4) times the temperature raised to the fourth power. the equation is:
E = σT4
Since the first star is twice as hot as the second, then the star won't produce twice the energy, but 16 times the energy due to the Stefan-Boltzmann constant. It's also important to know that this law only applies to blackbodies.
Debt relief is when debts are either reorganised to make them more manageable, or reduced. Microfinance loans are when money is lent to LICs to help them to develop. These are often small loans with reasonable interest rates. They are available to people and businesses who may normally struggle to get credit.
The sea affects the climate of a place. Coastal areas are cooler and wetter than inland areas. ... In the summer, temperatures can be very hot and dry as moisture from the sea evaporates before it reaches the centre of the land mass
I believe the correct answer from the choices listed above is the second option. In the summer, temperatures exceed 100 f, whether it's a cloudy day or clear day. The seasonal weather condition expressed here is the summer. It <span>is the hottest of the four temperate seasons, falling between spring and autumn.</span>
