General Science Questions

We all know that green is one among the three primary colors in additive mixing.

By mixing blue and yellow colors we get green color.

The weight of an object is minimum when it is placed at the center of the earth because when an object is in the center, it experiences gravitational pull from all directions.

In troposphere and mesosphere, temperature declines with increasing altitude. In stratosphere and thermosphere, temperature increases with increasing altitude.The coldest temperatures in Earth’s atmosphere occur at the top of mesosphere, the Mesopause, especially in the summer near the pole.Transitional layers of atmosphere include tropopause, stratopause, and mesopause. These layers are relatively thin and are located between major layers of atmosphere. These have contrasting thermal properties. Hence, in these layers there is no change in temperature with change in altitude.

All are correct. Gravitational waves don’t get distorted or altered by interactions with matter as they go through space. gravitational waves have pure information about the objects and events that created them. The Government of India has given approval for the world’s third advanced Laser Interferometer Gravitational Wave Observatory (LIGO-India) to set up in India.

Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon and the Sun and the rotation of Earth.

Statement 2 is also correct. But it is not the correct explanation for the 1st statement.
