Answer:
I think the sun is the right answer
Answer:
the moment of inertia is 380.14 kg-m^2
Explanation:
The computation of the moment of inertia is as follows:
The net moment of inertia is
= MR^2 ÷ 2 + m_p d_p^2 + m_d d_d^2
= 135 × 1.95^2 ÷2 + 63.7 × 1.05^2 + 30.1 × 1.33^2
= 380.14 kg-m^2
hence, the moment of inertia is 380.14 kg-m^2
We simply applied the above formula so that the correct value could come
And, the same is to be considered
Answer:
Very hot during the day and very cold at night.
Explanation:
Due to the thin atmosphere, they have very hot climate during the day time and very cold climate at night. This happens because they contain very low amounts of greenhouse gases. These gases retain the heat at night. The atmosphere also prevents excessive light and UV rays from entering. The thin atmosphere leads to many asteroids and comets hitting the surface of the planet. On earth, these asteroids usually, burn up in the mesosphere layer of the atmosphere. These asteroid collisions cause massive fires. This in turn, causes the temperature to increase during the day. During the night time, massive fires cannot burn due to the low temperature because of the lack of greenhouse gases.
Answer:
(B) 1.41 x 10^{10} N/m^{2}
Explanation:
diameter of wire (d) = 0.6 mm = 0.0006 m
radius of wire (r) = 0.0006/2 = 0.0003 m
tension (force F) = 20 N
percentage strain = 0.5 %
what is the Young's modulus?
Young's modulus = 
where
stress = 
stress = 
stress =70735530.3 N/m^{2}
- strain = percentage strain ÷ 100
strain = 0.5 ÷ 100 = 0.005
therefore Young's modulus = =
= 1.41 x 10^{10} N/m^{2}
