-- Mr. Galonski looks at himself in the mirror while he shaves in the morning, using visible light.
-- On his way to work, he listens to music and news, taking advantage of all the radio waves around.
-- While walking from his car to his office, he takes his jacket off and rolls up his sleeves, so his arms can soak up some ultraviolet from the sun, and get a little bit of color.
-- Mister Galonski is actually DOCTOR Galonski DDS ... a dentist. He uses a machine that produces X-rays, to take pictures of his patients' teeth and jaws. He glues the pictures into a big scrap-book that he keeps on the coffee table in his living room.
The layer of electrically charged molecules and atoms which spans 40-250 miles above ground called ionosphere causes the display of the aurora and the reflection of radio waves back to earth.
I believe we live in the Cenozoic era
We live in the Holocene Epoch, of the Quaternary Period, in the Cenozoic Era (of the Phanerozoic Eon).
Answer:
B
Explanation:
because it has more power
Answer:
Put the two solid spheres on an inclined plane
. Use a meter-stick to hold the spheres on the plane. Release the two spheres at the same time and let down roll down. Observe the two spheres as they roll down and repeat the steps. The hollow sphere will roll last while the solid sphere will roll first. The hollow sphere has more rotational inertia than the solid sphere. This is because the mass of the hollow sphere is distributed farther from its center of gravity.
Explanation:
The description of the experiment for the two spheres is given below:
1. Put the two solid spheres on an inclined plane
.
2. Use a meter-stick to hold the spheres on the plane.
3. Release the two spheres at the same time and let down roll down.
4. Observe the two spheres as they roll down and repeat the steps.
5. The hollow sphere will roll last while the solid sphere will roll first. The hollow sphere has more rotational inertia than the solid sphere. This is because the mass of the hollow sphere is distributed farther from its center of gravity.
