Answer:
You'd have to show the picture..
D I think I really don’t know
Combined the speed force with the flash is speed and zoom s speed and then get 24=48,28
Answer:
If the temperature of the solar surface is 5800 K then the approximate temperature of the sunspot is a) 4400 K.
Explanation:
The most straightforward way to solve this is using Stefan-Boltzmann law that states that I the energy radiated per unit surface area per unit time (watt per unit area ) of a black body is proportional to the fourth power of the temperature T of the body:
with being the Stefan constant.
A black body is an idealized physical body that is a perfect absorber because it absorbs all incident electromagnetic radiation and is also an ideal emitter. The Sun is considered to be a black body at different layers and different temperatures.
We are told that the intensity of a sunspot is found to be 3 times smaller than the intensity emitted by the solar surface , that means that:
then using the expression of Stefan-Boltzmann law we get that
we cross out and use the fourth root in each side of the equation
then we use that
So finally we get that
