Answer:
179 degree
Explanation:
Solid copper will lose heat to warm up and melt ice . Since all the ice has not melted so final temperature of mixture will be zero.
heat gained by ice to reach temperature of zero degree
= mass of ice x specific heat of ice x rise of temp
= 2 x 2093 x 16 = 66976 J
Heat gained to melt 1.1. kg of ice
mass x latent heat of ice
1.1 x 334000
= 367400
total heat
= 367400 + 66976
=434376
Heat lost by copper
= 6.3 x 385 x T
where 385 is specific heat of copper and T is initial temperature
heat lost = heat gained
6.3 x 385 T = 434376
T = 434376 / (6.3 x 385)
= 179 degree .
Answer:
(c) The planet must have a mass about the same as the mass of Jupiter,
(d) The planet must be closer to the star than Earth is to the Sun.
Explanation:
Astrometry is the ideal method to detect high-mass planets that are close to their star. That is because the gravitational effect that it will have the planet over its host star will be greater. This effect can be seen as a wobble in the star as a consequence of how they orbit a common center of mass¹. The center of mass will be closer to the most massive object, So, in the case of an extrasolar planet with masses like Jupiter (Jovian), this point will be a little bit farther from the star, making the wobble more notable than in a system with a low-mass planet.
Key terms:
Astrometry: study of the position of the stars over time in the sky.
¹Center of mass: a geometrical point in which the mass from a whole system is summed.
It should tasks that you must do in order for it to be a good schedule.
La energía limpia es energía libre de carbono que genera poca o ninguna emisión de gases de efecto invernadero. ... La energía renovable es la energía que proviene de recursos que se reponen naturalmente, como la luz solar, el viento, el agua y el calor geotérmico.
