A circuit consists of a wire, a lightbulb, a switch, and a battery. What would happen if the switch were replaced with a section of wire?
O A. The voltage and resistance would both decrease.
OB. The voltage would decrease, and the resistance would increase.
O C. The voltage would increase, and the resistance would decrease.
O D. The voltage and resistance would be the same.

muscle endurance

explanation:

i can do 50 in a row ( but i get so tired after that)

explanation:

v=uf/(u-f)

= 5.-10/(5+10) convex lens has negative focal length

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.

c) up is the direction the magnetic force is acting on the charge.
