Answer:
a force that is able to act at a distance
Explanation:
:)
Answer:
Centripetal acceleration does not change speed but it changes direction as it is a single thing moving in a circular path. Most accelerations, like linear acceleration, cause things to move in a straight line. But, both centripetal and angular acceleration are vectors.
Answer:
570 nm
Explanation:
The wavelength of an electromagnetic wave is given by:
where
is the speed of light (the speed of the electromagnetic waves in a vacuum)
is the frequency of the emitted light
Substituting the numbers into the equation, we can find , the wavelength of the emitted light:
No. The forces of gravity between them would remain unchanged after those three changes.
