Question : 1
The color of the star is an indication of its
a) Temperature
b) Luminosity
c) Distance from the sun
d) Distance from the earth
Answer »Answer: (a)
The color of the star is an indication of its temperature. The glowing is caused by something called Black-Body radiation, which has to do with the heat energy trying to radiate away in more and more energetic wavelengths.
Red stars are relatively cool at only a few thousand degrees Celsius, white stars are hot at about ten thousand degrees, and blue stars are the hottest.
Question : 2
Which one of the following is the largest satellite in the solar system?
a) Europa
b) Triton
c) Titan
d) Ganymede
Answer »Answer: (d)
Ganymede is the largest satellite in the solar system. Ganymede is a satellite of Jupiter and the largest moon in the Solar System.
It is the seventh moon and third Galilean satellite outward from Jupiter. Completing an orbit in roughly seven days, Ganymede participates in a 1:2:4 orbital resonance with the moons Europa and Io, respectively.
It has a diameter of 5,268 km (3,273 mi), 8% larger than that of the planet Mercury, but has only 45% of the latter’s mass.
Question : 3
Scientists have determined the temperature near the Earth’s center 1,000°C hotter than was reported in an experiment run 20 years ago. The actual temperature is?
a) 4,000° Celsius
b) None of these
c) 5,000° Celsius
d) 6,000° Celsius
Answer »Answer: (d)
These measurements confirm geophysical models that say that the temperature difference between the solid core and the mantle above must be at least 1,500° C to explain why the earth has a magnetic field.
The research team, which was led by Agnes Dewaele from the CEA, a French technological research organization, used X-rays from the European Synchrotron Radiation Facility (ESRF) in Grenoble, France, as a key investigating tool.
Question : 4
Which of the following is called “Blue Planet”?
a) Jupiter
b) Mars
c) Earth
d) Saturn
Answer »Answer: (c)
Earth is the Blue Planet because of the vast encompass of oceans on its surface. From space the oceans combined with the atmosphere make the planet look blue.
The abundance of water on Earth's surface is a unique feature that distinguishes the 'Blue Planet' from others in the Solar System.
Question : 5
Consider the following statements:
- The albedo of an object determines its visual brightness when viewed with reflected light.
- The albedo of Mercury is much greater than the albedo of the Earth.
a) Both 1 and 2
b) Neither 1 nor 2
c) 2 only
d) 1 only
Answer »Answer: (d)
The albedo of an object determines its visual brightness when viewed with reflected light. Albedo is the fraction of solar energy (shortwave radiation) reflected from the Earth back into space.
It is a measure of the reflectivity of the earth’s surface.
