the value of 4C3+5C3+6C3...12C3 is equal to??​

Answer:

Explanation: Cross product of vectors A and B is perpendicular to each vector A and B. ∴ for two vectors →Aand→B if →C is the vector perpendicular to both.

Step-by-step explanation:

a, b, c are non-zero vectors and a is perpendicular to both b and c.Find a unit vector perpendicular to both →a and →b, where →a=ˆi−2ˆj+3ˆk and →b=ˆi+2ˆj−ˆk. Hint: In cross product (or vector product) of two nonzero vectors $\vec a$ and $\vec b$, the resultant vector is perpendicular to both vectors $\vec a$ and $\vec b$.

Answer:

Warm sea surface temperatures, which reach a peak in late summer, are required to create and maintain the warm, humid air mass in which tropical cyclones grow. This provides energy for storm development through the heat stored in humid air called latent heat.

The tropical cyclone developed in the late summer due to high heat of water and mixing of ocean waters in Northern hemisphere attains maximum temperature in late summer that is August.

• Cyclones are violent storms that originate in the tropical area over oceans and it move to the coastal areas causing destruction.

• The cyclones occurring in the late summer has the advantage that the sun is exactly over the equator and the other advantage is that the air is overheated.
