The manufacturer of a 1.5 V D flashlight battery says that the battery will deliver 9 mA for 40 con- tinuous hours. During that time the voltage will drop from 1.5 V to 1.0 V. Assume the drop in volt- age is linear with time. How much energy does the battery deliver in this 40 h interval

a small object of mass 3.66 g and charge -17.6 µc is suspended motionless above the ground when immersed in a uniform electric field perpendicular to the ground. what are the magnitude and direction of the electric field?

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.

technology is the application of the knowledge gained by science.
