Answer:
83.2 W/m^2
Explanation:
The radiation per unit area of a star is directly proportional to the power emitted, which is given by Stefan-Boltzmann law:
where
is the Stefan-Boltzmann constant
A is the surface area
T is the surface temperature
So, we see that the radiation per unit area is proportional to the fourth power of the temperature:
So in our problem we can write:
where
is the power per unit area of the present sun
is the temperature of the sun
is the power per unit area of sun X
is the temperature of sun X
Solving for I2, we find
Answer:
Please find the answer in the explanation
Explanation:
Given that a scientist conducting a field investigation records measurements of very low pressure and high relative humidity at the top of a mountain.
Since a weather map indicates that a warm front is approaching the mountain, according to the conventional current, the warm front is approaching because the weather must have been in higher relative humidity in cool air.
The warm front is approaching to replace it so that the cool air can conventionally replace the warmth air too.
The condition the scientists will most likely observe at the top of the mountain will be high relative humidity.
Answer:the resistance decrease
Explanation:
A negative ion is a atom that has an extra electron, but the same # of protons
The acceleration goes up.
