The charge entering the positive terminal of an element is q = 5 sin 4 π t mc while the voltage across the element (plus to minus) is v = 3 cos 4 π t v (a) find the power delivered to the element at t = 0.3 s

123.30 W

Explanation:

We have given q = 5 sin 4πt

And voltage across the element V =  3 cos 4πt

We have to find the power delivered

So

We have to find the power at 0.3 sec

So

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.
