On november 21, the subsolar point would be falling on which latitude at solar noon?

On November 21, the subsolar point would be falling at solar noon on   Somewhere between the equator and 23.5°S latitude  .

Explanation:

Solar point is a point where sun perceives to be exactly overhead. therefore sun light hitting at 90° angle to the earth's surface .

The subsolar point cross the Equator on the September and march equinoxes.

On November 21 , the subsolar point would fall at solar noon

Somewhere between the equator and 23.5°S latitude

heat released by collision processes during accretion, and heat from decay of radioactive elements

explanation:

radiative zone

explanation    

radiative zone is the layer of the sun which energy is transferred away from the core by radiation. although, the core is the only part of the sun that produces an appreciable amount of heat through fusion. in fact, 99% of the energy produced by the sun takes place within 24% of the sun's radius.
