Answer:

c. Main Sequence

Explanation:

90% of the stars in space are in the main sequence stage.

Nebula is a cloud of dust and hot gases where stars are born. Giant and white dwarf are types of stars.

A plot of star temperature vs luminosity is used to classify all the stars. This plot is known as HR diagram. When plotted on the HR diagram, 90% of the known stars lie on the main sequence stage of the HR Diagram.

A wooden disk of mass m and radius r has a string of negligible mass is wrapped around it. If the disk is allowed to fall and th
Tju [1.3M]

Answer:

a = \frac{2}{3}g

T = \frac{mg}{3}

Explanation:

As the disc is unrolling from the thread then at any moment of the time

We have force equation as

mg - T = ma

also by torque equation we can say

TR = I\alpha

TR = \frac{1}{2}mR^2(\frac{a}{R})

T = \frac{1}{2}ma

Now we have

mg - \frac{1}{2}ma = ma

mg = \frac{3}{2}ma

a = \frac{2}{3}g

Also from above equation the tension force in the string is

T = \frac{1}{2}ma

T = \frac{mg}{3}
