A car battery has a rating of 290 ampere-hours. This rating is one indication of the total charge that the battery can provide to a circuit before failing. (a) What is the total charge (in coulombs) that this battery can provide

The total charge that can be delivered is 1044000 Coulombs

Explanation:

As we know that current I flowing given by:

I=Δq/Δt

Where Δq is charge moving

Δt is time

So

Δq=IΔt

Δq=290A×1 hour

Δq=290A×3600s

Δq=1044000 Coulombs

The total charge that can be delivered is 1044000 Coulombs

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.
