The magnetic flux through each of five faces of a die (singular of ''dice'') is given by φb = ±n wb, where n (= 1 to 5) is the number of spots on the face. the flux is positive (outward) for n even and negative (inward) for n odd. what is the flux through the sixth face of the die?

Ф6 = 3 Wb

Explanation:

the flux is positive when N is odd and positive when N is even so we can write the flux through the all side as

∑ N=1, to5

∑ -1 ^N Ф N * Ф6 =0

∑ -1 ^ N * Ф6 =0

Where :

ФN=N

Replacing and operated so  

-1 Wb +2 Wb - 3 Wb + 4Wb - 5Wb + Ф6=0

Ф6 - 3Wb = 0

Ф6 = 3 Wb

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.
