The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. Essentially Pluto meets all the criteria except one—it “has not cleared its neighboring region of other objects.
Answer:
Big Bang theory has occurred because about two thousand million years ago, a star came close to the sun. The molten mass on it melted and formed a huge mountain. Due to the high pressure, the star repelled back and the mountain separated into pieces. These pieces started revolving aound the sun and are known as planets. The existence of these planets is known as big bang theory.
Explanation:
Answer:
Average speed of the car A = 70 miles per hour
Average speed of the car B = 60 miles per hour
Explanation:
Average speed of the car A is 
(Equation A) and Average speed of the car B is 
(Equation B), where 
and 
are the distances and 
and 
are the times at which are travelling the cars A and B respectively.
We have to convert the time to the correct units:
1 hour and 36 minutes = 96 minutes
From the diagram (Please see the attachment), we can see that at the time they meet, we have:
(Equation C)
(Equation D)
From Equation A and C, we have:
208-x+16 = x
208 + 16 = 2x
x = 112 miles
Replacing x in Equation A:
Replacing x in Equation B:
Answer:
I guess the answer is
-The mass and volume of an object determine if it will sink or float
Explanation:
An object that has a higher density than the liquid it's in will sink. An object that has a lower density than the liquid it's in will float.
density=mass/volume
If it is GAINING mass, the kinetic energy increases because it's still moving. If it stopped, it would then become potential energy.
