Molecular clouds range in mass from a few times the mass of our Sun (solar masses) to 10 million solar masses. Individual stars

range from 0.08 to about 150 solar masses. What does all of this imply about how stars form from molecular clouds

Answer:

Explained in Depth.

Explanation:

It is all matter of what kind of stars are we talking about, for simplicity let's say we are talking about normal stars such as our sun.

If there is a molecular cloud that has a mass that is slightly larger than our sun then it is possible that the gravity will eventually pull together cloud into a sphere that would have enough mass to start nuclear fusion which is important to become a star.

Mass of such cloud would be 1.98x10^30Kg almost equal to the sun's mass.

All of this implies that stars are formed when there is enough mass to let gravity pull it all together into a sphere that has enough gravitational pull to start nuclear fusion inside the core.

How do I Change the following to decimal numbers.<br> a. 5.93 x 10-5
PSYCHO15rus [73]

Explanation:

To convert from scientific notation to decimal, move the decimal point 5 places to the left.

5.93×10⁻⁵ = 0.0000593

a bowling ball of mass 7.3 kg and radius 9.6 cm rolls without slipping down a lane at 3.1 m/s . part a calculate its total kinet
erma4kov [3.2K]

49 J   is the total kinetic energy. If a bowling ball of mass 7.3 kg and radius 9.6 cm rolls without slipping down a lane at 3.1 m/s. Kinetic energy is the energy an bowling ball has because of its motion.

Given:    m = 7.3 Kg ;  r = 9.4 cm = 0.094 m   ;   v = 3.1 m

Now total kinetic energy in this case is given by KE = Kinetic energy due to rotation  + Kinetic energy due to translation

i,e     KE = 1/2*m*v2   +   1/2*I*ω2      where   I is the moment of inertia of the bowling ball about it's center and ω is the angular velocity

Now for pure rotation (without slipping)    v = rω  

also for the ball (solid sphere)  I = 2/5*m*r2

Hence our kinetic energy becomes  

 KE = 1/2*m*v2 +  1/5*m*v2 = 7/10*m*v2

so   KE = 0.7*7.3*(3.1)2 = 49.10 J = 49 J

Imagine another solar system, with a star of the same mass as the Sun. Suppose a planet with a mass twice that of Earth (2 Earth
sashaice [31]

Answer:

Time period, T = 403.78 years

Explanation:

It is given that,

Orbital distance, a=1\ AU=1.496\times 10^{11}\ m

Mass of the Earth, m_e=5.972\times 10^{24}\ kg

Mass of the planet, m_p=2m_e=11.944\times 10^{24}\ kg

Let T is the orbital period of this planet. The Kepler's third law of motion gives the relation between the orbital period and the orbital distance.

T^2=\dfrac{4\pi^2}{Gm_p}a^3

T^2=\dfrac{4\pi^2}{6.67\times 10^{-11}\times 11.944\times 10^{24}}\times (1.496\times 10^{11})^3

T=1.28\times 10^{10}\ s

or

T = 403.78 years

So, the orbital period of this planet is 404 years. Hence, this is the required solution.
