Uma lanterna é alimentada por 4 pilhas de 1,5 V, tal como se representa na figura. Qual é o valor da diferença de potencial nos terminais da associação das 4 pilhas?

he kicked it 10 feet straight up into the air? i think this works.

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.

connect the batteries in series and hope
