Ampere second could be the unit of : o power o conductance o energy o charge

Charge

Explanation:

Unit of ampere is defined as the coulomb of charge per unit time which is in seconds.

Here, i is in ampere, qis the charge which is in coulomb, and the t is in sec which is time.

Therefore,

Charge=ampere-second.

Therefore, the unit ampere-second will represent the charge.

laticia draws the diagram below to show earth’s magnetic field.

answer

the arrows to the right of earth should point up.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
