Mary and her younger brother alex decide to ride the 17-foot diameter carousel at the state fair. mary sits on one of the horses in the outer section at a distance of 6.5 feet from the center. alex decides to play it safe and chooses to sit in the inner section at a distance of 6 feet from the center. what is mary's centripetal acceleration am compared to that of alex's centripetal acceleration aa? give your answer as a multiple of aa aa

with 5 seconds, no, but over time if the police car stays at 65m/s ad the speeding car stays at 60, then obviously yes, but the answer to your question would be, no.

hope this : )

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.

5 w for 1hr = 5x60x60 joules=300x60=3000x6=18,000j as total energy conversion. efficiency of bulb needed for radiant to thermal within 18000
