An 8-bit adc has a digital resolution of %.

0.39 %

Explanation:

We have given 8 bit ADC and we have to find the resolution of the ADC

The resolution of the ADC is given by where n is the number of bit

Here in question we have given 8 bit ADC so n = 8

So resolution is given by =0.39%

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.
