Use equations of motion to find the velocity just before it hits the floor:
<span>Vf^2 = Vi^2 + 2gx </span>
<span>Final velocity = 4.42m/s </span>
<span>Impulse is change in momentum so: </span>
<span>m(Vf - Vi) = 0.05(0 - 4.42) </span>
<span>= - 0.221 kg.m/s

Answer:
Explanation:
The energy of a single photon is given by:
where
h is the Planck constant
c is the speed of light
is the wavelength
For the photon in this problem,
So, its energy is
One mole of photons contains a number of photons equal to Avogadro number:
So, the total energy of one mole of photons is
Answer:
Forces include gravity, friction, and applied force. Force causes changes in the speed or direction of motion. These changes are called acceleration
Explanation:
I hope I am correct my Science teacher said this was the answer to your question
The Earth's axis' orientation in space gradually shifts due to the precession.
Precession is the name given to this motion, which is characterized by a cyclic wobble in the direction of the Earth's axis of rotation over a period of 25,772 years. The third motion of the Earth to be discovered, following the much more evident daily rotation and yearly revolution, is precession. The axial tilt of the Earth gradually changes over time as a result of precession. The points on the Earth's orbit where the equinoxes and solstices fall will shift over time. As a result, 13,000 years from now, the location of the summer solstice will change to that of the winter solstice. The Earth's axis changes its direction due to precession. In relation to the stars, the celestial poles steadily shift.
