It is definitely letter D. <span>A1 and B1 are like poles, but there is not enough information to tell whether they are north poles or south poles.
A1 and B1 is either both north poles or both south poles. Repulsion of both magnets says it all--like poles always repel while opposite poles always attract. Thus, the best conclusion to this would be choice D.</span>
Answer:
91.64 km
91.64 km high material would go on earth if it were ejected with the same speed as on Io.
Explanation:
According to Newton Law of gravitation:
Where:
G is gravitational constant=
For Moon lo g is:
According to law of conservation of energy
Initial Energy=Final Energy
For Jupiter's moon Io:
Velocity is given by:
For Earth Velocity is given by:
Now:
91.64 km high material would go on earth if it were ejected with the same speed as on Io.
Answer:
Energy is stored in the bonds between atoms
Answer: The answer is true
Answer:
Tides on our planet are caused by the gravitational pull of the Moon and Sun. Earth's oceans "bulge out" because the Moon's gravity pulls a little harder on one side of our planet (the side closer to the Moon) than it does on the other. The Sun's gravity raises tides, too, but lunar tides are twice as big.
