a tungsten filament of 1000-W light bulb radiates 2-W light. If the filament has surface area of 0.25mm^2 and emissivity of 0.95, find the filament temperature. (stefan boltzmann constant=5.67×10^-8 W/m^2K^4)​

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.

the body's situation won't change the forces are equal opposit and on the same body

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.
