The option that accounts for more than half the mass of the asteroid belt is A) Ceres, Vesta, Pallas, Hygiea, and Euphrosyne contain half the mass.
<h3>How to explain the asteroid?</h3>
The asteroid belt is roughly between the orbits of Jupiter and Mars. They are also known as minor planets and serve as a source of information about the solar system.
The total mass of the asteroid belt is estimated to be 2.81021 to 3.21021 kilograms, which is only about 4% of the mass of the moon, and Ceres, Vesta, Pallas, Hygiea, and Euphrosyne contain roughly half of this mass (approx 50%).
One thing to note is that ceres is the largest of them all. As a result, option A is the best choice.

Answer : Time taken for the light to reach earth is 
Explanation :
Given that,
Speed of Ultraviolet light, 
Distance covered by the light, 
We have to find the time taken (t) by the light to reach on the surface of earth.
t = 133333333.333 seconds
or
Hence, this is the required solution.
we know that
the speed is equal to
The slope of the line on the graph is equal to the speed of the car
so
during the segment B the slope of the line is equal to zero
that means
the speed of the car is zero
therefore
<u>the answer is the option B</u>
The car has come to a stop and has zero velocity
An artificial satellite is one that was manufactured by people ... most likely on Earth ... and then launched and placed into orbit around Earth, the sun, the moon, a planet, an asteroid etc.
