Answer:
our sun is one of the least 100 billion stars in the milky way a spiral galaxy about 100000 light years across
Gravity is the attraction of every body to every other body due to the masses of each body. The larger the mass, the greater the force. It also depends on the distances: the closer the bodies, the greater the force. Gravity is directed toward the center of a body, and the distance is measured from the center.
When objects fall to the ground, gravity causes them to accelerate. Acceleration is a change in velocity, and velocity, in turn, is a measure of the speed and direction of motion. Gravity causes an object to fall toward the ground at a faster and faster velocity the longer the object falls.
C explanation: There are many examples of fossils found on separate continents and nowhere else, suggesting the continents were once joined. If Continental Drift had not occurred, the alternative explanations would be: They swam to the other continent/s in breeding pairs to establish a second population. ...
Explanation:
It is given that,
Density of asteroid, 
Mass of asteroid, 
We need to find the diameter of the asteroid. The formula of density is given by:
V is the volume of spherical shaped asteroid, 
r = 2441311.12 m
Diameter = 2 × radius
d = 4882622.24 m
or
Hence, this is the required solution.
