Help a Girl Out and Answer This you will get Brainliest, Thanks, and more points if your answer is correct (: So I already know A is where the suns energy is produced.

Here are the options for the rest :

• region of the sun that is visible from earth

• appears as a red ring around the sun right before and after the peak of a total solar eclipse

• region that energy travels to through radiation ( movement of high energy particles )

• appears as a white ring or crown around the sun at the time of total solar eclipse

so please tell me the answer for each ( A, B, C, D ) thank you !

What is the weight of a feather (mass = 0.0001 kg) that floats through earth's and the moon's atmospheres?

Assume you measured the mass of the cart to be (500 ± 1) g and the mass of the additional mass you put on the cart to be (500 ± 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass

Air enters a gas turbine with two stages of compression and two stages of expansion at 100 kpa and 17°c. this system uses a regenerator as well as reheating and intercooling – the intercooler returns the air to the inlet temperature. the pressure ratio across each compressor is 4 ; 300 kj/kg of heat are added to the air in each combustion chamber; and the regenerator operates perfectly while increasing the temperature of the cold air by 20°c. determine the system’s thermal efficiency. assume isentropic operations for all compressor and the turbine stages and use constant specific heats at room temperature.
