Answer:
D) hot stars and interstellar gas, particularly hydrogen
Explanation:
Emission nebula is the nebula which is formed of the ionized gases which emit light of different wavelengths. The common source of ionization of the emission nebula is high-energy photons mostly which are emitted from hot star present nearby to it.
<u>The emission nebulae include H II regions. An H II region is the region of the interstellar atomic hydrogen which is ionized. It is the cloud of the partially ionized gas in which star formation takes place.</u>
Ok so the answer will be 1.39km.
First use SOH-CAH-TOA
Sine (SOH)=Opp/Hyp
Sin (8°) = vertical height/hypotenuse
Hypotenuse = 10 km
Vertical height =?
vertical height = sin (8°) × 10km = 1.39 Km
I hope this helps. :3
Answer:
as the mass of an object is increased, the acceleration of the object is decreased & vice-versa.
Explanation:
hope this helps!
The maximum speed is 0.55 m/s
Explanation:
For an object in uniform circular motion, the force of friction between the object and the ground provides the centripetal force required to keep the body in motion. Therefore we can write:
where the term on the left is the frictional force and the term on the right is the centripetal force, and where
is the coefficient of static friction
m is the mass of the body
g is the gravitational acceleration
v is the speed of the body
r is the radius of the circular path
In this problem, we have:
r = 0.102 m
Substituting and re-arranging, we find the maximum speed v at which the salt shaker can rotate:
