Answer:
The moon does not get pulled into the sun because of gravitational pull.
Explanation:
Gravitational pull is a force that pulls things down or into i guess you can say. Like are orbit, all of the planets (even the dwarf planet "pluto") are circling around are sun but we have things called moons that circle are planets. Are moon is orbiting us like we (are earth) are orbiting the sun. So to get into a little more detail, i will add that we circle the sun or the moon circles us because the action of earth pulling away from the suns gravitational pull is causing it to either rotate or revolve.So we are stuck in the gravitational force of the sun and the moon is stuck in ares. But as someone who LOVES astronamy will say that i watched a video about are earth, sun, and moon and it said that each year are moon is slowly pulling away from the earth. sooner or later we might not have a solar or lunar eclipse anymore.
Answer:
3 : 08 : 10.9
Explanation:
assuming a 12 hour clock
angular velocity of the hour hand is 2π/(3600(12)) rad/s
angular velocity of the minute hand is 2π/3600 rad/s
difference is 2π/3600 - 2π/(3600(12)) = 11(2π/(3600(12)) rad/s
45° = π/4 radians
This angle is covered in a time of
π/4 rad / 22π / (3600(12)) = 900(12) / 22 = 490.909090... s
or about 8 minutes 10.9 s
ANSWER 3:08:10.9
<span>Answer:
initial I = (m/2)L²/3 + (m/2)L²
where L = ½ the length of the rod, and the vertical half can be treated as a point mass.
initial I = mL²(1/6 + 1/2) = 2mL²/3
final I = m(2L)²/3 = 4mL²/3
Since I has doubled and momentum is conserved, ω has halved.
ω = 3.9 rad/s.
Formulaically: 2mL²/3 * 7.8rad/s = 4mL²/3 * ω</span>
No. Force isn't something you can enclose in a box, an envelope,
or a bottle.
A stick of dynamite contains some amount of a chemical compound which,
when triggered by enough heat or shock, undergoes a chemical reaction
that proceeds very rapidly, and generates a large quantity of gases before
the gases can dissipate. This creates very high pressure around the reaction,
and it's this pressure in a small volume that exerts great force for a very short
time. The whole process is often described as an "explosion".
Answer:
A. aluminum, iron, and silver only
Explanation:
metal elements are great conductors; aluminum, iron, and silver are all metals.
plastic isn't an element, but it still doesn't conduct electricity very well because it isn't a metal
(so I would leave out plastic, because you can only choose 3 max based on the answer choices)
