Answer:
SUPONIENDO QUE NO HAY FRICCIÓN
Explanation:
F = 66 kg(
) = 132 N
Answer:
It would be A.
Explanation:
When oxygen is released, that oxygen rises and the ballons temperature will go down. Heat rises so if the ballon is dropping, then the temperature is dropping.
Answer:
Explanation:
The time taken by a transverse wave to propagate from one end to another depends on the number of oscillation made by the wave itself. If the total number of oscillation of the wave is known, the time taken by the wave to propagate through can be determined.
Note that the term "period" is the time taken by a transverse wave to complete one oscillation. So if we know the number of oscillation made in one second by the wave and the total oscillation made, then we can know determine how long it will take a transverse wave to propagate from one end of the string to the other
Answer:
Explanation:
Essentially, Kinetic energy of the particle must equal the combined potential energies of earth and the moon when the object is on the moon's surface, meaning the full equation is
<h3>
</h3><h3 />
=Mass of Earth=
=Mass of Moon=
=distance from earth's center to the moon's=
=radius of moon=
After some algebra, the equation simplifies to
Plugging in the values of G, which is 
, should yield the proper answer of 2780m/s.
